Selecting the protocols for the rear ports
To define the protocols to be used, a setting is done on the local HMI under the menu:
Configuration/TerminalCom/SPA-IEC-LON
When the protocols have been selected the terminal will automatically restart.
When communicating with SMS or SCS with the SPA or IEC 60870-5-103 protocol the slave
number and baud rate (communication speed) settings must be equal in the PC-program and in
the REx 5xx terminal.
Using the SPA rear port
The slave number and baud rate settings of the rear SPA port on the REx 5xx terminal, for SPA
bus communication, is done on the local HMI at:
Configuration/TerminalCom/SPACom/Rear
Using IEC 870-5-103 rear port
The slave number and baud rate settings of the rear IEC 60870-5-103 port on the REx 5xx ter-
minal, for IEC 870-5-103 bus communication, is done on the local HMI at:
Configuration/TerminalCom/IECCom/Communication
Using LON rear port
The LON port is not affected by eventual restricted settings valid for the SPA/IEC port. When
communicating via the LON port, the settings are done with the LNT, LON Network Tool. The
settings are shown on the local HMI at:
Configuration/TerminalCom/LON Com
From this menu, it is also possible to send the "ServicePinMsg" to the LNT.
Downloading the configuration and setting files
When downloading a configuration to the REx 5xx terminal with the CAP 531 configuration
tool, the terminal is automatically set in configuration mode. When the terminal is set in config-
uration mode, all functions are blocked. The red LED on the terminal flashes, and the green LED
is lit while the terminal is in the configuration mode.
When the configuration is downloaded and completed, the terminal is automatically set into nor-
mal mode.
For further instructions please refer to the users manuals for CAP 540 and PST.
