Message Meaning Type
PLC IN PROGRAM MODE
Run Mode
Error
A status message indicating that the PLC is not in the
RUN Mode, it is in PROGRAM Mode. The PLC is

is unable to send message triggers or variables to
the DL40 at this time.
PRINTER ERROR
Print Mode
Error
While attempting to send data to the printer, an error
was detected on the RS–232 port. This can be
caused by a missing or incorrectly wired printer
cable, improper baud/data bit/parity selections, or
electrical noise picked up by the cable.
RACK CONFlG. ERROR
Configuration/Status
During Power–Up
Error
An invalid combination of rack size and starting
module group have been entered on the DL40 DIP
switches. An example of such an error would be a
starting module group of 2, with a full rack size.
