11 Sensor

– Actuator Bus (MODBUS RTU)

The S200 measuring and control device is equipped with a sensor - actuator bus.
The MODBUS RTU protocol is used.
The hardware is a RS 485 interface.
Shielding = terminal 94
A = + terminal 93
B = - terminal 92
+12V = terminal 91
0V = terminal 90
A max. load of 200mA is allowed for the 12V power supply.

11.1 Shielding

The use of shielded cables offers a high protection against electromagnetic interference,
especially against high frequencies. However, the effectiveness of the shielding is dependent
on a careful installation of the cable.
The shielding is placed near the ModBus master.

11.2 Communication parameters

Baud rate:

9600 bps

Data bits:

8

Start bits:

1

Stop bits:
