Quickstart Guide
ABB PLC and drives integration using Modbus RTU
IP configuration of CPU (for Ethernet connection between PC and PLC)
If the CPU has an Ethernet port and the CPU IP address has not already been configured, follow the steps below.
De‐activate the firewall of the PC, or allow the connection if question comes up. Connect an Ethernet cable
between PC and PLC (or via a switch).
Open the IP configuration tool from the "Tools" menu and press the "Scan" button.
Select actual PLC from the scanned objects (1), make your network settings (2) and press the "Send Configuration"
button. This needs to be done the first time you connect to the PLC even if the IP address is already correct.
Note! The PLC needs to be in "STOP" mode for IP configuration.
After the new configuration was sent the PLC will automatically reboot.
