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_RETAIN_ERROR
The Dialog-Controller has detected a difference be-
tween 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 situation; 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automatic startup of a possibly outdated PLC pro-
gram.
Error correction:
Either load, save and then start the new PLC pro-
gram 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and possibly outdated program.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 retain 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 program 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 present and must
be supplied with power at the time the program
starts.
Error correction:
Check the number and type of E-bus modules en-
tered in the controller configuration. Check the con-
tacts and wiring connections on these E-bus modu-
les. Once the number of actually available E-bus
modules agrees with the controller configuration
setting, the controller can be restarted using a reset
command.
