APPENDIX 2.1 Reading M-code
The program example for reading M-code at the completion of positioning start or
positioning is shown below.
The judgement of the positioning start completion and positioning completion is made
with the following signals.
• Positioning start completion ………M2400+20n (positioning start complete signal)
• Positioning completion ……………M2401+20n (positioning complete signal)
[Program Example]
(1) A program that outputs the M-code from PY000 to PY00F to external destination
after conversion into BCD code at the positioning start completion is shown below.
