I/O Signal Comparison - Mitsubishi Electric MELSEC L Series Manual

HIGH-SPEED COUNTER MODULE REPLACEMENT

6.2.3 I/O signal comparison

Sequence programs need to be changed because the I/O signal assignment differs.
For details of the I/O signals and sequence programs, refer to the MELSEC-L High-Speed Counter
Module User's Manual.
When the built-in I/O functions of the LCPU are used, the special relay is used. For details, refer to the
MELSEC-L CPU Module User's Manual (Built-in I/O Function).
