For all settings and configuration via the SPA communication bus, the SPA/IEC 870-
5-103 port on the rear, it is necessary to first deactivate the restriction for settings. Oth-
erwise, 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:
&RQILJXUDWLRQ7HUPLQDO&RP63$&RP5HDU6HWWLQJ5HVWULFW
It is also possible to permit changes between active setting groups with ActGrpRestrict
in the same menu section.

The SPA and the IEC use the same rear communication port. To define the protocol to
be used, a setting is done on the local HMI under the menu:
&RQILJXUDWLRQ7HUPLQDO&RP63$,(&3RUW
When the type of communication protocol is defined, the power to the terminal has to
be switched off and on.
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.

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:
