We have the following setup,
XMii 12.0
UDS 4.0
RSLinx as the OPC
I have setup a simple OPC DA tag in a test PLC. I have also setup the alias configuration with groups and items. I am able to read and write numeric values to the PLC.
However, I am not able to write character strings. Even if I set the data type for the item within alias config as a "VarChar", I am not able to write a string to the PLC. It gives a type mismatch error.
Does UDS not support writing alphanumeric characters to a PLC ? What am I missing ?
Regards,
Ramesh
