3.12.2 RS485 interface − EPM−S650
This module can be used to communicate with field devices via an RS422 or RS485
interface. For access to devices with an RS422/RS485 interface, the protocol of the field
device must be implemented in the control system in each case.
The following handling blocks are provided:
IPC / control Programming via Bus system Handling block
