11.3. Ethernet communication
The DIRIS Digiware M-50/M-70 gateway and DIRIS Digiware D-50/D-70 display can communicate over Ethernet using
multiple communication protocols (Modbus TCP, BACnet IP, SNMP v1, v2, v3 & Traps).
Example of architecture using an M-50/M-70 gateway:
U-xx
M-50/M-70
Ethernet
Digiware Bus
I-35
S-xx
Digiware bus
terminating resistor
11.4. Ethernet and RS485 communication
In the event that the system needs to communicate to a second PLC via RS485, you can configure M-50/M-70 gateways
and D-50/D-70 displays as RS485 slave to communicate via the RS485 bus in addition to the Ethernet bus.
Example of architecture using a D-50 or D-70 display:
DIRIS Digiware D-50/D-70
U-xx
RS485
Digiware Bus
I-35
S-xx
Digiware bus
terminating resistor
Ethernet
The following rules must be observed:
- A 120 Ω resistor must be added at the start of the RS485 link
- A 120 Ω resistor must be added at the end of the RS485 link
- An end of line resistor must be added at the end of the Digiware bus.
11.5. Communication tables
