FX indexing problem

[WKla]

This instruction works: MOV D202 D0V1 But when I am trying to use the index register with M type devices: LD M8000 SET M0V1 the next error appears: Error: F0137 Illegal device used or symbol not valid Anyone knows other possibilities to do the same thing (indexing M type devices) ? Thank you.

Hi That's not possible unless you're using an FX3U CPU. You could use an index on a dataregister and than use the DECO instruction to get the same result.

FX-series does not support bit indexing, except FX3U. Use words instead. Use [WOR K1M0Z H1 K1M0Z] instead of [sET M0Z], or [WAND K1M0Z HE K1M0Z] instead of [RST M0Z] Z may be any index register, and no other bits will be affected .

It works. Thank you.

Thanks for letting me know that something like Y20Z doesn't work on most Mitsubishi FX PLCs, despite what the programming manual says on Page 4-36.
