Establishing front port communication
When a PC is used to download settings and configuration, you need the terminal toolbox 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 stan-
dard 9-pole D-sub contact. This ensures a disturbance-free and safe communication with the ter-
minal.
When communicating from a PC, the slave number and baud rate (communication speed) set-
tings must be equal in the PC-program and in the REx 5xx terminal.
Procedure
1.
Plug the cable to the optical contact on the local HMI.
2.
Plug the other end of the cable to the COM port of the PC.
3.
Set the slave number and baud rate in the terminal.
The slave number and baud rate settings in the REx 5xx terminal is done
on the local HMI at:
Configuration/TerminalCom/SPACom/Front
4.
Set the slave number and baud rate in the PC-program.
The slave number and baud rate must be the same as in the terminal. See
the CAP 540 manual.
Establishing rear port communication
Settings can be performed via any of the optical ports at the rear of the REx 5xx terminal. 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.
Using the SPA/IEC rear port
For all settings and configuration via the SPA communication bus, the SPA/IEC 60870-5-103
port on the rear, it is necessary to first deactivate the restriction for settings. Otherwise, no setting
is allowed. This setting only applies for the SPA/IEC 60870-5-103 port during SPA bus com-
munication. The parameter can only be set on the local HMI, and is located at:
Configuration/TerminalCom/SPACom/Rear/SettingRestrict
It is also possible to permit changes between active setting groups with ActGrpRestrict in the
same menu section.
