8.5 Communication set-up
8.5.1 Connection overview
Fig. 43: UniSAB III communication channels
Fig. 43 is an overview of the communication channels in UniSAB III:
• An Ethernet channel connected by a switch or router
• An RS485 port used for sequencing communication between UniSAB III and UniSAB II
• An RS485 port used for e.g. connection to a VFD (Variable Frequency Drive)
• A Profibus/DP port used for connection to a PLC or other Profibus device
Through the Ethernet switch/router UniSAB III can communicate by Modbus/TCP with e.g. other Uni-
SAB III units, SCADA applications, UniHMI, UniSim and Johnson Controls RADAR.
For more information, see the relevant manuals for Modbus/TCP, Profibus/DP or RS2LAN.
8.5.2 Configuration of Ethernet channel
See subsection 8.4.2 on how to set up the UniSAB III IP address. You may use different ranges of “free”
IP addresses intended for small closed LAN nets, e. g. you may use the 192.168.10. xxx IP number
range, as suggested here. Use CAT5 Ethernet cables to connect UniSAB III to the switch or router.
