Hi all,
I've contacted Rockwell numerous times about the PointGuard card faulting with the 16#0203 fault. I've implemented ALL of their suggestions but still consistently see the fault. Allow me to explain what is going on.
I have a 1768-L45S with 1768-ENBT communicating to 4 1734-AENTRs. Each rack has various standard point I/O and safety point I/O. All but one rack does not exceed the allowed CIP limit of 20. All but one rack does not exceed the power limitations of the AENTRs (added 1734-EP24DCs where necessary).
Every now and then (say 5 - 10 minutes), ONE of the safety cards on the network will fault with the 16#0203 and soon after it will return to running status, but the fault causes the safeties wired to that card (Estops, Guard switches, etc) to drop out or rather the processor looses the ability to read the card.
Rockwell has told me to increase the RPI, to increase the network timeout, to make sure my power limitations aren't being exceeded, to update firmware, to make sure CIP connection is below 20, to change rack connection to "none"...
I've done all of this with the exception of one AENTR rack, but the faults keep coming. Does anyone know a possible solution? Is the one rack that hasn't been changed a problem? I mean, would it cause the other safety cards on other racks to fault with the 16#0203 code?
Let me know if you need more details.
Thanks,
Eric
