hello
hope you all are doing well.
I want to ask if there is a way to read the PLC ports without knowing the names assign, it should show all port available in the PLC Linux python.
I used the following command
read_items = data_access_service.Read(("Arp.Plc.Eclr/test_in1", "Arp.Plc.Eclr/test_in2", ))
read_item1 = read_items[0]
read_item2 = read_items[1]
but in the above command line I know the port name, but I want to call it general and show me all ports available. thanks in advance
There is a „Dictionary“ available via the REST interface, that returns a list of all the HMI variables that can be accessed:
Dictionaries This topic shows how to retrieve the dictionaries for the REST data interface, and gives exemplary postman collections for the commands that are described thoroughly in the respective topics. Unfortunately there is currently no equivalent available as an RSC service (C++ or gRPC). In those cases, you need to know the names of the variables.
okay
thank you
