Get Started with Nexto Xpress - MQTT communication

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.

Attached example project as described in the document

Get Started with Nexto Xpress - The Basics

Nexto Xpress is a powerful compact programmable logic controller (PLC). It is a part of the Nexto family from Beijer Electronics. Nexto Xpress delivers high performance in a compact format.

Nexto Xpress fits in small applications and as remote I/O. It has up to 43 on board I/O and is easily expandable via built-in ports, such as Ethernet, CAN and RS-485.

Get Started with Nexto Xpress - High speed datalogging

This document describes high-speed data logger 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

Get started with Nexto Xpress - IEC60870-5-104

The Nexto Xpress series from Beijer Electronics include a driver for communication via the IEC protocol IEC60870-5-104.

IEC60870-5-104 was originally a protocol developed for the energy sector, but is also widely used in infrastructure projects for roads and railways.

To test the communication, a small test-project in the Scada-system zenon from Copadata is used. Zenon has certified IEC drivers and a widely used Scada system in the energy sector.

Attached PLC-project, library and SCADA-application as described in the document.

The document is in English and Norwegian language.

ARTI connections include iX connection with ARTI driver, BCS Tools connection and Codesys OPC DA server connection.

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 - 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/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:

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.
