Appendix 2 I/O Signals
List of I/O signals
The following table lists the I/O signals of the high-speed counter module.
For details on the I/O signals, refer to the following.
Page 55 Input signals
Page 57 Output signals
• The I/O numbers (X/Y) in this section apply when the start I/O number of the high-speed counter module is
set to 0.
• The use prohibited signals are used by the system and is not available for users. If any of those signals is
used (turned off and on) by users, the performance of the high-speed counter module is not guaranteed.
