When a PC is used to download settings and configuration, you need the terminal tool-
box CAP 540 (including CAP 531 and PST).
A special cable is needed when connecting a PC to the front of the REx 5xx terminal.
This cable can be ordered from ABB. It must be plugged into the optical contact on the
left side of the local HMI. The other end of the cable shall be plugged directly into the
COM-port on the PC. The cable includes an optical contact, an opto/electrical converter
and an electrical cable with a standard 9-pole D-sub contact. This ensures a disturbance-
free and safe communication with the terminal.
When communicating from a PC, the slave number and baud rate (communication
speed) settings must be equal in the PC-program and in the REx 5xx terminal.

Settings can be performed via any of the optical ports at the rear of the REx 5xx termi-
nal. When a PC is connected to the SMS system, the CAP 540 and the PST softwares
are used. Settings can also be done via the SCS system, based on MicroLIBRARY.
