hi all
i run RSLogix 5000 to download a program to Logix5555
i use 1756-IB16D for digital input
in the I/O configuration i choose that module, and choose compatible keying
i also click the "major fault on controller when connection failed in run mode" option
when i go to run mode, after a few second, an fault occurs
the fault error code is
error 23 : at least one required connection is not established before going in to run mode
then i try to change the electronic keying to disable keying option, run it again, and it works
why is it?
is there something wrong in the I/O configuration?
i think i choose the right module
i appreciated ur respond
thx a bunch
