6 posts in this topic

In Mitsubishi Q series, if a bit M5 is set, is it will reset again if I OFF and ON again the PLC? Sorry, but i got no Mitsubishi plc to test it with me. Thanks

Yes, it will be reseted by PLC, unless some instruction which using this bit is active. Edited by konev

Depends on PLC parameters. You set the battery backed range in PLC parameters.

Hi dsc, the setting page of device latch is in the picture. But device M cann't be backed by battery.

If you need that the bit variable will be latched, you should use L instead of M. Note: L and M variable with the same number are not the same, they stores in different areas of memory.
