im using a pv550 keypad, rs485 only(2711-k5a2, frn 3.14), with a 1747-L531 slc5/03, 8k, os302.
when i try and setup an ascii keypad enable, or cursor point, the strings do not display in the ST file theyre being sent to. when i leave the .1 off the address in the pv tag the .len jumps huge...figured it would. but when i put it back in, nothing shows up in the address, no .len, no characters whatsoever.i assume my plc address is wrong, therefore the tag in the pv is along with it.
so my question is this: when defining a symbol(in logix500) for a specific address do i just go with(example>) ST20:0? or ST20:0.1? when i do the .1 in logix it changes to .DATA[0]
ive seen some posts recommend .DATA[1]
whats the right format at each end? do i have to write the .len myself in ladder?
Thanks so much in advance.....
