Posted 18 Feb 2013 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 Share this post Link to post Share on other sites
Posted 18 Feb 2013 (edited) Yes, it will be reseted by PLC, unless some instruction which using this bit is active. Edited 18 Feb 2013 by konev Share this post Link to post Share on other sites
Posted 19 Feb 2013 Depends on PLC parameters. You set the battery backed range in PLC parameters. Share this post Link to post Share on other sites
Posted 19 Feb 2013 Hi Crossbow, can you be more specific. Is it the parameter tab I attached here? Tq Mitsubishi PLC parameter.bmp Share this post Link to post Share on other sites
Posted 19 Feb 2013 Hi dsc, the setting page of device latch is in the picture. But device M cann't be backed by battery. Share this post Link to post Share on other sites
Posted 19 Feb 2013 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. Share this post Link to post Share on other sites
