Posted 2 Aug 2013 Hi all, i'm hoping this will be pretty basic but ive not worked with mitsubishi before so i don't know, i have a mistubishi plc program, with co comments or tags, but thankfully i have the iifix scada to go with it, im having a bit of confusion with the tags though, for example, in fix i have the tags Fix32.SCADA1.PLC2_DIGREG_M832.F_0 Fix32.SCADA1.PLC2_DIGREG_M832.F_1 Fix32.SCADA1.PLC2_DIGREG_M832.F_2 now i can find the tag, M832, in my second PLC no problem, but what does the f_0 mean?

Posted 3 Aug 2013 Hard to say. Maybe you should ask the question in the HMI/SCADA forums, Mitsubishi only has "M382" and nothing more to it. If you were to have e.g. D382_f0, ...f1, ...f2 and so on I would say that they refer to bits in words (f0 = bit0, f1 = bit1 and so on). But coils (Mxxx) are only coils... Must be a "fix thing". 1 person likes this Share this post Link to post Share on other sites
Posted 7 Aug 2013 kaare_t, thanks for your post, what i have found to be happening is that if the HMI tag is pointing to M382_F1, then in the plc it is looking at M383, it seems to do this in groups of 8, not sure why perhaps the way the OPC server was configured Share this post Link to post Share on other sites
