Open Discussion / Local display Raspberry 4
« on: November 17, 2022, 07:32:30 AM »
Hello,
I wrote an application on Raspi 4 with openPLC. AHMI was connected by modbus TCP and Visualisation on a Windows PC worked nice without problems.
Now I wish to transfer this Visualisation vom PC to PLC. It should start automatically, wenn the Raspi4 starts.
PLC should work alonestanding with the AdvancedHMI-Visualisation develloped on the PC.

What do I have to do / to transfer?
Which folders have to be used/created, to make the things running.

Thank you very much for help.

Thank you Archie.
Response to bachpi: I am a absolute beginner with respect to AHMI/OpenPlc. I worked more the 15 years on codesys and may be I'm a little spoiled by using this complete system of PLC-programing+built-in HMI with complete documantation.

What I need is simply an example program, written in ST with OpenPLC, with demo-varialbles of all types, which are displayed and/or manipulated with AHMI via modbusTCP. That will be absolute enaugh to find my way.

Hello,
I need some help in rather stupid questions, because I did not find something like a complete written tutorial.

My first steps:
I wrote a small program with openPLC (ST) witch runs at raspberryPi4. ModbusTCP installed and running.
It`s just a very simple thing, to check the possibilities of AHMI.
Did a lot of things in Codesys. I will try to change from Codesys to OpenPLC together with AHMI.

- what is the PLCaddressvalue, and where did I get it (e.g. to display real variable "var_1" from somewhere in the program

- if PLCaddressvalue is a internel address of the machine, it should change when I modify my plc-programm. Do I have to change the PLCaddressvalue in AHMI after each modification of my plc-program ?

- are simple exampels available for displaying variables and for input numbers in variables (usual IED 63111 types) 

Thank you very much for help
