Cable Break Procedures
A cable break in any location between either of the following produces data of 0 in the data
table for all inputs down stream of the cable break:
•
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.
Network
Flashing green
The module is online with no connections in the
established state.
Establish connections to other nodes. As a group 2
module, allocate the module to a master.
Off
No power.
Wait until the module has completed the dup_MAC_id
test or power the module.
