Figure27: Modbus RTU Communications Wiring
If inserting multiple wires in the terminals, ensure to properly twist wires together prior to inserting them into the terminal connectors.
The RS-485 port must be configured in EC- gfx Program prior to use. Modbus devices are integrated into EC- gfx Program using the EC- gfx Program Mod-
bus device block.
Modbus TCP Communications Wiring
Connect Modbus TCP devices to the same IP subnet the controller is using. This connection can be made by connecting the Modbus TCP device to an
Ethernet port on the ECY-CSC with a Cat5e network cable for example (see Communications Wiring [pg.16]). For more connection options, refer to the
ECLYPSE User Guide.
The RS-485 port must be configured in EC- gfx Program prior to use. Modbus devices are integrated into EC- gfx Program using the EC- gfx Program Mod-
bus device block.
M-Bus Communications Wiring
M-Bus communications are made by connecting meters directly in an M-Bus port.
The Connected System Controller integrates one M-Bus port when equipped with one ECY-MBUS extension module.
The M-Bus port must be configured in EC- gfx Program prior to use. M-Bus meters are integrated into EC- gfx Program using the M-Bus device block.
Maximum M-Bus Device Wiring Length
The following information provides wiring limitations for M-Bus devices. The wiring length provided below was tested as a worst-case scenario with all
meters being located at the end of the bus. If meters are more evenly spaced along the bus, then the maximum wiring length can possibly be increased.
Testing Conditions:
Current per slave/meter 1.5 mA
Max ∆V accepted on the bus 2 V
Cable capacity 110 nf/km
HD15 Connection:
M-Bus Meters AWG 15 AWG 22
300, 2400, 9600 Bps 300, 2400, 9600 Bps
10 5000 m (16404 ft) 1200 m (3937 ft)
20 2500 m (8282 ft) 550 m (1804 ft)
30 1500 m (4921 ft) 350 m (1148 ft)
40 1100 m (3608 ft) 250 m (820 ft)
50 850 m (2788 ft) 200 m (656 ft)
60 650 m (2132 ft) 150 m (492 ft)
