Note!
This module can only be actuated on a bus coupler module with HW version
1D or higher.
This module features an RS232 interface for access to field devices with an RS232 interface.
For access to devices with an RS232 interface, the protocol of the field device must be
implemented in the control in each case.
The following handling blocks are provided:
IPC / control Programming via Bus system Handling block
