Nexto XPress-serien fra Beijer Electronics inkluderer et bibliotek (LibMQTT) for

kommunikasjon via protokollen ‘Message Queuing Telemetry Transport’ (MQTT).

MQTT er en lettvekts-protokoll som krever lite båndbredde. Den kan også krypteres

og er dermed godt egnet for kommunikasjon mot skytjenester (IIOT).

Kommunikasjonen foregår mellom en klient (f.eks Nexto XP325) og en servertjeneste

(Broker). Når en klient har publisert data inn til Broker, kan andre klienter abonnere

på disse.

The Nexto XPress series from Beijer Electronics includes a library (LibMQTT) for communication via ‘Message Queuing Telemetry Transport’ (MQTT).

MQTT is a lightweight protocol that requires little bandwidth. It can also be encrypted and is therefore well suited for communications against cloud services (IIOT).

Communication takes place between a client (eg Nexto XP325) and a server service (Broker). Once a client has published data to Broker, other clients can subscribe to it.

This document describes how we can log high speed data in Nexto XPress.

The Nexto XPress series from Beijer Electronics includes a library (LibDatalogger) for logging high-speed data to local files in CSV format. The files are stored in persistent memory for later analysis in a spreadsheet (eg Excel®). The minimum logging frequency is 10ms in triggered mode and 100ms in continuous mode.

The generated CSV files can be stored as follows:

• Internal FLASH memory (retrieved with BCS Tools)

• USB memory

Attached example project as described in the document

Resources

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).

Resources

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

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.

They are required to represent rational numbers, and according to IEC-standard and documentation of CODESYS the floating point values can be both REAL (32 bits) and LREAL (64 bits).
Value range for REAL: 1.175494351e-38 to 3.402823466e+38
Value range for LREAL: 2.2250738585072014e-308 to 1.7976931348623158e+308

Test in BCS NEXTO-series and NX3010 (same in NX3020, and NX3030.
REAL (32-bit) and LREAL (64-bit), it works!

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.

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.

This is an example of when using Nexto as Modbus Master to RS-485 slaves by using a the Ethernet to RS-485 gateway, JetPort 5601.

Configuration

Nexto Modbus RTU over TCP --- TCP/IP --- JetPort 5601 --- RS485 --- NA-9173 --- NA-9173.

For each slave configured in Nexto a seperate TCP session is established, therefore it is important that the Gateway supports multiple sessions. (This is valid for the Modbus Symbol Client driver, by using the IEC address based Modbus Client driver one TCP session can be created for several slaves. Another option when using the Symbol driver is to make a sequence and disconnect the slave after each polling))

In this case the JetPort 5601 supports 5 sessions (clients) at the same time.

(A startup problem has been detected with the 1.06 FW in JetPort 5601. By disabling one connection communication starts and then the other can enabled again.)

Resources

Gratuitous ARP:
NET1 Ethernet interface of NX5000 module sends spontaneously ARP type packets in broadcast, informing its IP and MAC address for all devices interconnected to the network. These packets are sent during the download of a new application by the BCS Tools software and in the startup of a NX5000 interface. 5 ARP commands are sent, with an initial interval of 200 ms, doubling the interval between every new triggered command, totalizing 3 s. Example: First trigger occurs at time 0, the second one at 200 ms, the third one at 600 ms and so forth until the fifth trigger occurs at time 3 s.

In BCS Tools there is a setting that will affect the Modbus protocol for the Client driver.

Modbus TCP should be used when communicating to other Modbus TCP units. A TCP session will be established with every slave and requests will be sent in parallel to all configured slaves.

Modbus RTU over TCP should be used when communicating to other Modbus RTU slaves connected on a serial line like RS-485/RS-232 through a ethernet to serial gateway. Some gateways are strictly media converters and some can act as Modbus gateways. When using a non Modbus gateway Modbus RTU over TCP should used in Nexto and if the gateway can act as a Modbus gateway Modbus TCP should be used.
A TCP session will be established for every configured slave but the requests for all configured will be sent in a sequence.

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

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:

Resources

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.

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.

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.

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.

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
