Read/Write memory locations without using tags

Post by iorthree »

Hi,
we would like to directly address from scripting some MODBUS registers locations (usually mapped to some tags).
We need to use it like a base address with offset addressing for variable lists indexing.
Is there any way to do that?
Many thanks

A solution maybe to write a TCP/IP or Serial Modbus Driver using script. There is no direct access to the Driver API since it resides in a separate DLL located inside a shared program files directory folder. Its deployed separately than DLLs located inside the IX directory and uses OPC also subjected to frequent changes.
