All digital-expansion inputs produce data of 0 if the expansion cable
is removed. No status is in the default produced assembly. Attribute
101 in the identity object reports module faults.
If no faults are present, an explicit message GET command returns 0.
If the ribbon cable is disconnected, it returns 0x04, which is for
module location change. The module LED indicator also flashes
indicating a fault if an expansion is disconnected. Select an alternate
produced assembly that contains the expansion status byte, using the
EDS Properties configuration window.
