CJ1W-TS56x cards can be used with CJ1M. However, each card can use up to 6 words of I/O (96 bits). Therefore this will 'eat into your local I/O allocation. The CJ1M-CPU11 has 160 bits local I/O, CPU12 is 320 and CPU13 has 640. Please find enclosed a sample program with a Function Block to extract data from TS56x cards into more meaningful data.
