MMS-3 Error Codes
Modbus RS485
Connection
The
MMS-3
offers a standard RS232 port. It is necessary to supply an
RS232 - RS485 converter for the Modbus functionality.
Depending on the converter, the RS232 from the
MMS-3
is connected
to the terminal marked RS232 on the converter. The RS485 output
from the converter can be connected directly to the user's DCS system
(point to point) or to a multi-drop system
