• Base and digital input expansion module

• Digital input expansion module and another digital input

expansion module

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 status 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 dialog.
