Compact HMI 800 / 800xA, writing a value of data type "time" to AC800M via OPC
Hi,
I have time constants (data type "time") in the PLC code (AC800M) and I would like to be able to set these time constant from CHMI800 (the operator should be able to adjust the timers).
I cannot find any way to configure an OPC tag of the data type "time" in CHMI800.
I can use an OPC tag of type dint and convert the dint to time in the PLC, but I would prefer to use the data type "time" directly.
Anyone that knows if this is possible?
Thanks in advance

Hi,
Use string PCA in OPC and link it to the variable with datatype time. It works.
