Posted 17 Sep 2012 is you want more then the standards 8 words x 2 - then you could use a send receive response... ie use word L0 as the word that tells which frame of info you are sending... set up you initial set of words then put a 1 in L0 for set one...in PLC two copy the L0 to L8 then read back L8 and if = to L0 then write the next set of words to Lset L0=2 and repeat... a bit like a multiplexer... a bit of coding, but it can work...
