Library for HART functionality is necessary!
In order to be able to use the HART functionality, it is necessary to install and
incorporate the special WAGO HART library “WagoLibHART_0x.lib” in the
PLC application.
Additional Information
The library “WagoLibHART_0x.lib” can be downloaded free of charge from the
WAGO website at:
www.wago.com
→ Support → Additional documentation and information on

the right side.
10.1.1 Communication with 75x-xxx via PLC Library
Communication between the 75x-xxx couplers/controllers and the HART I/O
module is achieved by means of the library “WagoLibHART_0x.lib”.
This library enables easy access to the 6-byte mailbox of the I/O module and
provides the necessary HART commands, which can then be executed locally
from the PLC application.
