Using the SPA/IEC rear port
For all setting and configuration via the SPA communication bus, the SPA/IEC 870-5-
103 port on the rear, it is necessary to first inactivate the restriction for settings. Other-
wise, no setting is allowed. This setting only applies for the SPA/IEC 870-5-103 port
during SPA bus communication. 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.
When communicating with SMS or SCS via the SPA/IEC 870-5-103 port, 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/IEC 870-5-103 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 SPA/IEC 870-5-103 port on the
REx 5xx terminal, 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 Net-
work 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.
