- 100K-word PLC-5/V80 controller with a 32K-word limit per data-table file
- Addresses up to 2,944 I/O points across as many as 23 remote-I/O racks
- Supports four DH+/remote-I/O ports, RS-232 and as many as 16 MCPs
1785-V80B is the high-capacity controller in the documented PLC-5/VME comparison table.
Its 92-chassis remote-I/O ceiling and VME communication functions suit installations whose rack map and memory demand exceed the smaller V40 configuration.
Commissioning must verify the per-file memory limit, all four channel roles, remote-rack assignments and the host-side VME address allocation.
Availability, condition, price, and shipping time for 1785-V80B are confirmed during quotation.

- Use the 1785-V80B VME status file to monitor host-interface information
- Account for A16 registers and the configured A24 general-purpose memory window
- Verify VME message transfers, interrupt handling and host access before production startup
- Keep the restored design within 2,944 I/O points and 23 remote-I/O racks
- Map no more than 92 remote chassis across the four configurable network ports
- Check the 32K-word limit separately for every required data-table file
- Restore the documented 57.6, 115.2 or 230 kbit/s rate for every remote-I/O channel
- Confirm that no project dependency assumes an extended-local I/O port
- Validate RS-232, DH+, remote-I/O and VME-host communication as separate paths
- High-capacity PLC-5/VME systems requiring up to 100K words of controller memory
- Remote-I/O architectures approaching 2,944 points, 23 racks or 92 chassis
- VME-host applications using PLC-5 status files, message transfers and interrupts
