PLCnext Technology & PLCnext Controls

Hello, I am currently setting up a connection between an RS458 interface and an RS UNI module. The connection between both participants is to be realised via a 5 m long cable. Unfortunately, I can't get the RS UNI running and send some telegrams/data packets. Immediately after starting the system, the pin xBusy = High …

Hello team I'm starting a new project using PLCNext Enginnering with The CPU AXC F2152 and a Module converter from ModBus Serial to MQTT Broker, any advice before I start the development, or what not todo.. cheers!!!!!

Hi, we are working on an application based on the AXC F 1152 that will be deployed as a docker container consisting of the application and a database. We are worried about data loss and data corruption as we didn't find any information about how to properly shut down the device or what happens in case of a power loss.…

Hello, I've made a small PLC program where I have multiple function arrays. At the beginning of each PLC cycle I clear all the values in those arrays. After this the program is writing data to certain places in that array depending on the enabled functions. This is done every PLC cycle. I clear all the arrays to make s…

Hi, i wanted to implement a block that would set the value of a variable to True and after 5ms it would be False and then after 5ms again it would be True. I have attempted doing that using the FBs as shown below. But, after a while the value is stuck at True and the Not FB does not invert the input. Is there a workaro…

Hello Sir , Now ,we meet the requirement from customer that how to achieve program migration from one PLCnext to another through SD card. To avoid if one PLC couldn't work as normal.could we get the way to store the orginal program to SD card, and then we can meet the customers requirement. What's more, what the differ…

Good evening, I'm completely new to the PLCnext and trying to connect to a MQTT-Broker using IIOT_Library Version 2.0.0. I'm using an AXC F 2152 with HW02 and Firmware 2021.0.3. There are no problems creating the client object, but every time I'm trying to connect to the broker, the plc crashes and reboots. There are n…

Dear Sir/Madam, I was debugging my PLCnext Starter kit and unplugged it for half an hour. When I started working again, I find out that it is not booting up. Meaning that the Run light is not turning on the green. I did the factory reset using the button on my PLC 2152 hardware following the routine instructions but th…

Hi, What would be the simplest way to execute a script installed on the PLCnext in a cyclic way? Example, we have a python script in the PLC that reads variables through REST Data Interface and we want to cyclically execute that script. Is there a way to call it from the PLC programming (Through PLCnext Engineer)? Than…

Hi Team, For a project we are using a combination between HMI view and tablet/PC for viewing the webserver. Now these have a completly different resolution settings. It can be possible to make different pages that you need to visit manually, each for the expected resolution. But from my web building days I know there i…

Hi I'm actually playing with the OPCUA server. Is there a way to define events on the custom NodeSet2.xml file ? I used the alarm function block to send alarms to the client (that work correctly), but I can't find where those variables are declared. On the GDS config file, the alarms variables aren't defined. Can you…

Hello all, I've created a system with multiple PLCNext devices. The HMI of each device can be reached with a button on another HMI. The button is simply programmed to open a URL, which is in this case the IP of another PLCNext. This works okay, but after a while a lot of tabs are opened. Is there a way to open it in on…

Hello Sir We have a customer care about the TPM of PLCnext ,however, we have less information about the PLCnext TPM architecture and principle, what's more,how to implementation it.

Gday, Trying to setup the PLC and Master to read a slave device. [ AXC F 2152 PLC with AXL SE RS485] I only need to read from the slave and not write. From the Modbus RTU library, I'm using MB_AXL_SE_RS485_Master_4. Where do I setup the baud rate ? Thanks

HI, plcnext support I have a plcnext 3152, reviewing the equipment logs I repeatedly find the following messages: ¡ 07.12.20 09:54:20.778 Arp.Services.Wcm.Internal.IdentityStoreConfigurator ERROR - Failed to create Identity Store HTTPS-self-signed-Backup - Store exists already! 07.12.20 09:54:20.779…

Hey guys, just wanted to check and see if there was something I can do to tame the random values that I am getting from the SE AI 4-20 readings. Using a meter with a steady output, the reading is still jumping several hundredths (ie.. from 60.52 to 60.54 to 60.51, etc...) With a sensor attached its ridiculous. Im even…
