Modicon loadables

[Guest Guest_steve]

Does anybody have a user loadable for a DRUM - Modicon 984-685E ? I'm trying to write some sequencing for controlloing 30 ouputs based on a timed sequence and can't find the DRUM.USL loadable anywhere.

Whoa --- 984685E... its been a while since i played with one of those monsters... in fact i last used in in 1996, and it was old then. That was using Taylor Proworx Plus (Dos based) Not a bad package but i remember having to pay around $9500 for it with the simulator ... argh ! The ideal way would be to use shift registers but as far as i can remember, a shift register is not part of the instruciton set... The only way i can think of is using cascaded timers to fire sequence bits. Sorry..
