Hi All.. We have a little problem at the plant I work at...
we have been in contact with techconnect and not really achieved much so far.. just while we are waiting for a complete hardware swap to arrive does anyone have ideas for us. I think we are about out!
We have a L55 CLX on V13 with a RIO network with quite a few FLEXIO Racks on Series D 1794-ASB adaptors.
this morning we had one output (valve coil) short and take out the ASB (no lights) on the rack it was controlled from (and yes all the outputs have individual fuses)
we have:
replaced the ASB with the same series
set the dip's the same.
swapped all the TB3's out
restarted PLC (to reinitialise the block transfer)
swapped as many modules out that we have
did a download (rockwells request)
baud rates are correct. 232k
There is only discrete IO fitted IV16's & OM8's
Now the strange part:
1. The new ASB shows up in the IO tree as working with no errors.
2. The ASB has no errors at all. solid green light.
3. we have inputs LED's coming on at the flex IO from the field devices
4. Inputs DO NOT change state in the datatables at all
5. The RIO network daisychains past this cabinet and everything downstream and upstream on the same network is working fine...
in the diagnostics sometimes this cabinet appears as a full rack, other times as 3/4, others as 1/2. A full rack is installed (7 units)
I suspect the hardware.
