BCS Tools Nexto - Task priority and scheduling
In Nexto there are two schedulers, the Realtime scheduler
and the Normal scheduler.
The realtime tasks are
mapped to priority 0-15 i BCS Tools and tasks with priority 16-31 are mapped to
the normal scheduler.
What is the difference between a task
mapped to the realtime scheduler vs normal scheduler?
The
realtime tasks, Prio 0-15, are deterministic, this means that these tasks
will execute independently of communication (Modbus, etc....)
The normal
tasks, Prio 16-31, are not deterministic, this means that depending on the
system load the execution time willl be affected.
How are
tasks interrupting each other?
Tasks within the range 0-15 will interrupt each other and they will
interrupt the 16-31 tasks (normal), the lower number will interrupt the
higher number, and will execute until it finishes (unless another lower number
realtime tasks interrupts it).
Tasks within the range 16-31 (normal)
will not interrupt tasks within the range 0-15 (realtime). They will interrupt
each other and will be interrupted by system tasks and also by the realtime
tasks (0-15)
The task named MainTask is by default set to Priority
13 = realtime task -> deterministic execution
BCS Tools Nexto -After compilation Memory 0 - 6 are presented, what do these mean?
Size of generated code = is the space used on the application from the
program area.
Size of global data = is the space used on the application
from the symbolic variable memory
Memory 0 contains Data = Symbolic variables memory
Memory 1 contains
Retain Data = Retain Symbolic variables memory
Memory 2 contains
Persistent Data = Persistent Symbolic variables memory
Memory 3 contains
Input = Addressable input variables memory (%I)
Memory 4 contains Output =
Total addressable output variables memory (%Q)
Memory 5 contains Memory =
Addressable variable memory (%M)
Memory 6 contains Code = Program
memory
BCS Tools Nexto - When will the Persistent and Retain variables be saved?
Question:
When will the Persistent and Retain
variables be saved in Nexto?
Answer:
The Persistent and Retain variables are saved
at power off.
X = value is kept
BCS Tools Nexto - Diagnostic variables with IP address information
IP address information is available via the diagnostic variables or by using
the function blocks.
The information is available as string and byte.
For example using the function blocks refer to related links.
Clarification about the force function in CODESYS
Background
Force Variables is a feature created in
PLCs originally to force inputs, the purpose of this is to test the application
without the field signals.
Function
In all CODESYS based PLCs the force feature
works as a table of values to write to certain variables every PLC cycle.
Different from the write command that happens once, the write of force happens
every cycle. When it comes to internal variables that a written to in PLC code
the force function will not be effective.
In CODESYS
based PLCs (for example SoftControl, SoftMotion, Nexto, Xtorm and others) the
force function is executed twice in a cycle, once after read inputs and once
before write outputs according to the following picture.
Example of force of internal variable where
the user program will have prescendence.
BCS Tools Nexto - Task information and I/O update synchronization
When using the Basic project profile in BCS Tools 3 tasks are created.
MainTask
ExternInterruptTask00
TimeInterrruptTask00
Since the priority is within the range 0-15 all tasks are handled as
realtime tasks. (For more details regarding Task priority and scheduling see
related links.)
What is not seen in the project is that there is an
additional task called ConfigurationTask, this task handles services in the
backplane like "Read module diagnostics", "Send module parameters",
"Communication with NX5000 module", etc.....
This task has Priority 4 and
executes cyclic with an interval of 4 - 30ms depending on the amount of I/O
modules installed -> it will interrupt the MainTask.
This is an
example of why the communication processing of the NX5000(ethernet) module is
handled by the ConfigurationTask. Imagine that the application executed by the
MainTask takes approx 100ms to execute.
To maintain a good communication
performance the ConfigurationTask keeps interrupting the MainTask to ensure a
good communication bandwitdh with the NX5000 modules.
How is the I/O update synchronized
with the user program?
The I/O update is synchronized with
the MainTask and it is divided into three parts.
1. Read Inputs, CPU
sends an EtherCAT frame to get the inputs from the mounted modules
2.
Execute the POU:s associated with the MainTask.
3. Write Outputs, CPU
sends an EtherCAT frame to set the outputs to the mounted modules
When using additional tasks like a time interrupt task the I/O update is not
performed, if an I/O update is required in tasks you have to use the
REFRESH_INPUT/REFRESH_OUTPUT instructions located in the NextoStandard
library.
NX5001, Profibus DP Master.
The NX5001
works like a regular I/O module, however in this case the I/O image is much
bigger (while a regular module can have a few bytes of I/O, NX5001 can handle
up to 3584 bytes for inputs and 3584 bytes for outputs.
In the begining of
the MainTask (before running the user code), the CPU reads the input image from
NX5001, the same thing happens in the end of MainTask (after running the user
code) for the output image.
The Profibus DP scan is carried out in a
asynchronous mode totally indpendent of CPU<->NX5001 local bus scan.
NX5001 scans all Profibus DP slaves and store the input/output image into a
triple buffer scheme (internal to NX5001),
meaning that CPU can access
this data anytime without any need of waiting (data is always ready).
Consistency issues?
Since PROFIBUS has no support for 32-bit, the only way to achieve this is
mapping the information into two standard 16-bit channels.
This is a
standard practice found on several slaves. Regarding the consistency,
theoretically you would only have problems if these two 16-bit parts
could be accessed separately and asynchronously.
However this is
impossible.
- Data update on PROFIBUS Slave: the servo ensures that
these 2 16-bit parts will be updated on PROFIBUS Slave chip memory at the same
moment.
- NX5001 reads the inputs from the servo: all the inputs from that
slave will come in one same PROFIBUS telegram. (no way to read each 16-bit part
individually)
- CPU reads the inputs from NX5001: all the inputs (from all
slaves) are read in the same moment on MainTask before the execution of user
program.
MODBUS Master/Slave, DNP3
These protocols (MODBUS, DNP3 and any other future similar protocols) runs on
low priority ("normal" scheduler, non-real time). It means that they only run
when MainTask is not running.
They will only update data (%I, %Q or
Symbolic Data) when MainTask is not running, because they can not "wake up" and
execute during the execution of MainTask.
However, there is a special
case: MainTask can start to execute exactly when MODBUS is updating data
(because it is real time and can interrupt the MODBUS task).
The
consequence is that if MODBUS Master (for example) is performing a read command
of 125 Holding Registers, the MainTask can interrupt it in the middle of this
update so it may see some Holding Registers with value of previous polling and
some withe the value of the latest polling.
In this special case there is
an interlock implemented to lock MainTask execution when MODBUS is updating a
mapping data. Each mapping can have maximum of 250 bytes, in practice it will
take a few microseconds to copy this data.
MODBUS data is never
updated in the middle of MainTask execution (cycle time).
BCS Tools Nexto - Download Boot Application during RUN
The 'Boot Application' is the program code the cpu will load and execute after powering on or resetting the system. see, chapter 7.3 in KI00346. When a download is the made with the Nexto CPU in STOP mode the downloaded project will be registered as a Boot application.
NOTE! Online changes doesn’t update the Boot Application. this need to
be updated manually from the BCS Tool when logged in to the Nexto system. The
'Create boot applcaition can be performed with the CPU in RUN mode.
BCS Tools - Using the library NextoPID and Util at the same time causes a naming conflict for the PID instruction
Using the library NextoPID and Util at the same time causes a naming
conflict for the PID instruction when compiling.
To distinguish between different instructions with the same name but
located in different libraries use the following syntax,
"libraryname.instruction", NextoPID.PID.
BCS Tools Nexto - Add PID Loops online
Is it possible to add PID loops online without stopping control of the cpu?
In Nexto PID loops can be used together with a premade faceplate or only as FB. Regardless of type they can both be added online without stopping control.

REAL (32-bit) and LREAL
(64-bit)
64-bit REAL is fully supported in both Nexto modular and Xpress.
NOTE (from CODESYS online help):
- The support
of data type LREAL depends on the target device. Please see in the
corresponding
documentation whether the 64 bit type LREAL gets converted
to REAL during compilation
(possibly with a loss of information) or
persists.
- If a REAL or LREAL is converted to SINT, USINT, INT,
UINT, DINT, UDINT, LINT or ULINT
and the value of the real number is out
of the value range of that integer, the result will be undefined
and will
depend on the target system. Even an exception is possible in this case! In
order to get
target-independent code, handle any range exceedance by the
application. If the REAL/LREAL number is
within the integer value range,
the conversion will work on all systems in the same way.
BCS Nexto - How to update firmware in a Nexto CPU in RUN mode
The CPU has to be in STOP to update the firmware. If you cannot access the CPU from BCS Tools use the following procedure:
You cannot change the CPU state via web since it is a security issue.
What you can do is to power up the CPU with the top button pressed during the initialization period. After the boot-up time, the CPU will show "APP NOT LOADED" message and will not read the application from internal memory and run. It will remain in STOP mode.
Then you can easily update the firmware via the web interface.

Nexto - Reserved ports
Reserved TCP-/UDP-ports:
The following ports of the Ethernet
interfaces, both local and remote, are used by CPUs services,
so they are
reserved and cannot be used by the user: 80, 8080, 1217, 1740, 1741, 1742,1743
and 11740.
BCS-Nexto/Nexto Xpress - Number of supported ARTI connections
BCS-NX3010/3020/3030 = 8 ARTI connections (from firmware 1.5.0.10)
BCS-NX3003/3004/3005 = 8 ARTI connections (from firmware 1.7.49.0)
BCS-XP300/315/325/340 = 8 ARTI connections ( from firmware 1.7.46.0)
ARTI connections include iX connection with ARTI driver, BCS Tools connection and Codesys OPC DA server connection.
BCS Tools - The address %QBxxxxx not defined in any device
What does this comiler warning mean?
"The address %QB41653 is not
defined in any device. Perhaps address is not used"
Answer
The address %QB41653 is connected to the
diagnostics variables for the Profibus DP master, might be another address
based on the hardware configuration and cpu parameters.
The reason for
this message lays in the compiler, CODESYS was developed to use the %I and %Q
as IO mappings and the diagnostics in NEXTO are not IO mappings. When using the
diagnostics in the user application the compiler thinks that the usage of the
address is wrong since not being mappep as a IO mapping.
It is not
possible to disable this warning.
BCS Tools - OPC DA connection to the CPU or the simulator in BCS Tools.
When installing BCS Tools the OPC server from CoDeSys is installed in the background.
To configure the OPC server to connect to the simulation mode in BCS Tools
do the following:
(When connecting to the cpu this step can be ignored)
Set the project to simulation mode
Create the Symbol Configuration object and select the variables to be exposed.
Call the configuration screen for the OPC server.
Use these settings to connect to the simulator in BCS Tools.
Local host addr: 127.0.0.1
Device Port:
11739
Use these settings to connect to the CPU.
Local host
addr: IP address to the cpu
Device Port: 11740

Nexto Modular/Nexto Xpress - TLS support
Nexto Xpress with firmware 1.9.9.0 or later supports TLS 1.0, 1.1 and 1.2.
Nexto modular NX3003/NX3004/NX3005 with firmware 1.9.8.0 or later supports TLS 1.0, 1.1 and 1.2.
Nexto modular NX3010/NX3020/NX3030 all firmware versions only supports TLS 1.0.
Nexto modular/Nexto Xpress - MQTT TLS certificate validity check
At connection handshake when using certificates for TLS there is a validation check against the validity period of the certificate and the actual time set in the RTC.
Very important to make sure that the RTC is set with the current time otherwise the connection establishment will fail if the RTC is outside the validity period of the certificate.

BCS Nexto - ARTI/OPC communication
From BCS Tools 2.0 and cpu firmware 1.4.0.33 ARTII/OPC communication is supported.
- Keep in mind that this only works with the built-in ports and NOT the NX5000.
For example iX panels (TxA/ TxB / TxC) with CODESYS ARTI driver can communicate with BCS-Nexto system.
Example of a Modbus/TCP client via PLC code using the Oscat library
Example of a Modbus/TCP client via PLC code using the Oscat library
In the example Modbus Function Code 3 and 16 (read multiple holding registers and write multiple holding registers) are used to read and write 100 holding registers every 100 ms.
Example for Nexto (3010 CPU) is created with BCS Tools 2.03
Example for TxB-SoftControl (hardware with firmware 3.5.7.10) is created with CoDeSys 3.5 SP7 Patch 3
BCS Nexto Xpress/Modular - MQTT version
The current MQTT stack implemented in Nexto Xpress and Nexto Modular supports;
- MQTT v3.1.1
- MQTT v3.1
LTB Life Cycle Notification BCS-NX940x spareparts
BCS Nexto/Nexto Xpress - MQTT certificate support
When using encypted MQTT communication with TLS, communication is established by using X.509 certificates. These certificates can have different encoding schemes where one being the PEM(Base64 ASCII) or DER (binary).
Normally PEM files uses the extension *.crt, *.pem, *.cer and *.key and DER files normally uses *.der or *.cer.
With the current firmware:
Nexto Xpress XP3xx/Nexto modular NX3008 1.12.24.0
Nexto modular NX300x 1.12.23.0 and
Nexto modular NX30x0 1.10.8.0
in combination with LibMQTT 1.0.0.8 only Base64 ASCII encoded certificates can be used.
DER encoding scheme is no supported.
The manual states using certificated with *.crt extension, it is confirmed that also *.pem works fine as long as the enconding scheme is supported.
More details about encoding schemes and extension can for example be found here:
https://www.ssl.com/guide/pem-der-crt-and-cer-x-509-encodings-and-conversions/#ftoc-heading-2
Nexto I/O update with EtherCat master
The EtherCAT Master for Nexto have 2 "modes" of I/O update:
1)
Update all the I/O in one task only (bus cycle task)
2) Update the
I/O in the context of each task
The selection of this "mode" is made
by the following setting:
When this setting is checked, you are on "mode" 2.
Otherwise, "mode" 1. The bus cycle task ("mode" 1) is selected here:
For "mode" 1, by default the bus cycle task is
assigned to MainTask, but you can assign to some other task if you want. For
example, you can assign it for a TimeInterrupt task. In this case, Nexto I/O
modules will be updated on MainTask, and EtherCAT I/O will be updated on
TimeInterrupt (preempting the MainTask).
For "mode" 2, the EtherCAT
Master will perform the I/O update on the context of each task which uses some
EtherCAT I/O on some POU. So, it means that the bus activities can be spread
into several tasks.
The local bus I/O also have these two "modes",
and you can select it on the CPU configuration window:
Please note that these "modes"
are not an official terminology...it is just a way to help on the
explanation.
Regarding the REFRESH_INPUT/REFRESH_OUTPUT function,
they are very specific and must be used only on MainTask and only for local
Nexto I/O modules. If you want I/O update on other task than MainTask, you
should use the "update/messages per task" options described above.
Now, finally, lets take a look at the moment that the I/O update is performed
on each of these scenarios:
Nexto - Persistent variables loose their value if the name of the application changes
In the current and older versions of BCS Tools (2.05) and cpu firmware (1.5.1.3) if the application name is changed from "Application" to something else the persistent variables will loose their values every power off/on.
Currently you should use the default name "Application".
This issue has been addressed and will be solved in a future version of BCS Tools.
Always use the default name "Application"
Workaround
By using BCS Tools 2.06 and firmware 1.5.1.7 you can change name of the application and the persistent function will still work. This is valid for a single system. Do not change the Application name in a redundant setup.
Nexto - Check operating status of I/O modules
The attached document contains a "best practice" method to monitor the operational state of rack mounted I/O modules. This method is the recommended to use when creating interlock and alarms from the I/O modules.
BCS Tools - Edit CSV files with Excel 2013 or newer might destroy and make the csv files unusable for BCS Tools
When editing exported csv files with Excel 2013 or newer Excel might detroy the format of the csv files after saving it.
As a workaround OpenOffice Calc can be used instead of Excel.
