Eaton EMR-3MP0 - Profibus; Configuration of the Devices

3.4 Pro󰈌bus
Con󰃡guration of the Devices
After selecting Pro󰊎bus as the SCADA protocol (via setting [Device Planning] »Protocol« =
“Pro󰊎bus”), enter the menu branch [Device Para / Pro󰊎bus] ; there you have to set the
following communication parameter:
• »Slave ID«, to allow clear identi󰊎cation of the device This is a number from 2 to 125,
which must be unique among all Pro󰊎bus devices in the network.
In addition to that the Master has to be provided with the GSD-󰊎le. The GSD-󰊎le can be
taken from the Product-CD.
Some more (Pro󰊎bus-related) parameters that might be interesting are listed in the
Reference Manual.
CAUTION!
The trip signals are not part of the default con󰊎guration of the Pro󰊎bus protocol!
If it is required that trip signals are reported via Pro󰊎bus you have to explicitly assign
them to some Con󰊎gurable Binary Input. For example, you have to make settings like the
following one:
[Device Para / Pro󰊎bus / Con󰊎g Bin Inp xx‑yy] »Con󰅡g Bin Inp zz« = “50P . Trip”
Hardware Connection
• The hardware connection to the control system depends on the ordered hardware
variant (see ╚═▷ “Catalog Codes for the EMR-3MP0”, ╚═▷ “Communication Protocol
Codes”): At the rear side of the EMR-3MP0, there is either an RS485 (D-SUB)
interface or an optic 󰊎ber (ST connector) interface available for the Pro󰊎bus
connection.
• Connect bus and EMR-3MP0.
• Up to 123 Slaves can be connected.
•
In case of a D-SUB interface, terminate the Bus by means of an Terminate Resistor.
Error Handling
Information on physical communication errors (e. g. the detected baud rate) can be
obtained from the Event Recorder (see ╚═▷ “Event Recorder”) or the status display (menu
branch [Operation / Status Display]).
Error Handling – D-SUB Status LED
The Pro󰊎bus D-SUB interface at the rear side of the device is equipped with an status
LED.
