We have a 12 slot PLC5 Chassis. We've removed the PLC5 processor and replaced with a 1771-ASB, chassis set for 1 slot addressing. We are using this chassis and it's I/O as a remote rack for ControlLogix, comms via a DHRIO card channel B, in ControLogix chassis. The I/O in the PLC5 rack is as follows;
1771-ASB
DC Input 16 Channel (Rack 0, Group 0)
DC Input 16 Channel (Rack 0, Group 1)
DC Input 16 Channel (Rack 0, Group 2)
DC Input 16 Channel (Rack 0, Group 3)
DC Input 16 Channel (Rack 0, Group 4)
DC Output 16 Channel (Rack 0, Group 5)
Empty Slot (Rack 0, Group 6)
Empty Slot (Rack 0, Group 7)
Analog Input Card (Rack 1, Group 0)
Empty Slot (Rack 1, Group 1)
1771-QRD (Rack 1, Group 2)
Empty Slot (Rack 1, Group 3)
All the Digital I/O are fine as set up automatically as controller tags when RIO Adapter added to DHRIO card in I/O configuration.
The analog inputs are also fine, accessed using message block (i.e Block Transfer Write, Block Transfer Read), Path - DHRIO1 (card name), Module Address - RIO, Channel - B, Rack - 1, Group - 0, Slot - 0.
The 1771-QRD 'Pulse Flowmeter Module' which is messaged in a similar fashion to the analog card is not working, rate and total values are not updating.
We have tried this module in a test chassis with a PLC5 processor and it is working fine.
No errors on card or software, message block EN and DN flags not toggling. The 'Prog' LED on front of module is not lit, this should be flashing if block transfers are working.
Anybody have any ideas, would appreciated any help on this.
