I have a customer with over 50 old PLC2 they want to access by RS-232 serial. None have a 1771-KG card - which look pretty much like overkill at $1500 each (how many MicroLogix can I buy for $1500 ...) Has anyone seen any alternative solutions? Worst case we may end up just using some low-cost I/O to parallel sense the PLC2's inputs.
