3.3.2 > Link the DCS Modbus RTU lines
To get DSC MODBUS RTU line, connect the 9 ways D-type connector to the port of the Modbus
RTU/TCP Gateway (M7) on one hand and to the PC on the other hand.
There are two RTU/TCP Gateway in the MS102, you should connect it both to get redundancy
between the lines.
Therefore, please refer to part 3.4.1 Modbus RTU setup physical link.
3.3.3 > Link the DCS Modbus lines
To get DCS MODBUS TCP line, connect the two RJ-45 connectors to the port of the Ethernet Switch
(M9) on one hand and to the PC on another hand. You can also use the RJ-45 port on the front panel
too. Therefore, please refer to part 3.4.2 Modbus TCP setup physical link.
3.3.4 > Link the PC of monitoring lines
The Master Station is able to interface with a monitoring computer (optional) to control directly
valves’ automation. This PC Workstation, equipped with specific software, allows you to operate the
actuator and to retrieve data and alarms from the field units.
To link the PC Workstation and the Master Station MS102 together, use an Ethernet cable.
Connect one of both cable extremity to the Ethernet port of the PC, and the second to M9 unit or
to the Ethernet port on the front panel (X1) of the Master Station MS102 unit. For more information
refer to the NR 1178 PC Workstation for MS102 – Technical Manual.
3.3.5 > Link the Web server
The MS102 integrate a Web Server including several Web pages, so there is a TCP/IP connection to
access to these pages. This connection works via the RJ-45 connector of the Switch Ethernet (M9)
inside the Master Station, or on the RJ-45 input on the front panel (X1).
