3.3.3. PLC Window
The following PLC states can be displayed on Line 1 in the PLC window:
Display Description
STOP SWITCH ACTIVE
Operating mode selection switch S1 is set to the STOP position.
The PLC program can only be started with a programming tool if S1 is
set in the RUN position.
PLC STOPPED
Operating mode selection switch S1 is set to the RUN position.
However, the PLC programming tool forced the PLC program into the
STOP state.
PLC NO PROGRAM
Operating mode selection switch S1 is set to the RUN position, but no
PLC program is loaded.
PLC ERROR STOP
Operating mode selection switch S1 is set to the RUN position.
However, the PLC program could not be started due to an error.
If an error occurs when the PLC program is started, the following states
may be displayed on Line 2 in the PLC window:
Display Description
BOOTPROJECT_REJECTED_RE
TAIN_ERROR
The DIALOG CONTROLLER has detected a difference between the
PLC program saved as the boot project and the most recently loaded
PLC program. The latter was only loaded to RAM and was not saved as
a boot project. If the DIALOG CONTROLLER is switched off in this situ-
ation; the system notes the ID number of the program previously loaded
to RAM. The displayed message now prevents the automatic startup of
a possibly outdated PLC program.
Error correction:
Either load, save and then start the new PLC program or use a reset
command to start the saved and possibly outdated program.
RETAIN_IDENTITY_MISMATCH
The DIALOG CONTROLLER was unable to correctly reestablish the re-
tain variables.
Error correction:
By performing a reset, the saved PLC program can be started using the
reset retain variables.
RTSEXCPT_IOUPDATE_ERROR
One or all of the E-bus modules were not detected after the PLC pro-
gram started. The E-bus modules also include the I/O expansion cards
installed in the DIALOG CONTROLLER.
All E-bus modules entered in the controller configuration must be pre-
sent and must be supplied with power at the time the program starts.
Error correction:
Check the number and type of E-bus modules entered in the controller
configuration. Check the contacts and wiring connections on these E-
bus modules. Once the number of actually available E-bus modules
agrees with the controller configuration setting, the controller can be re-
started using a reset command.
