Again I am a bit of a neophyte when it comes to this stuff, so pardon the simple questions. I have a simple 20 line program that has four timed, conditional outputs that will cycle through in 6 seconds. I also have 4 stations that run the exact program, but they all start 1.5 seconds apart. Station 1 starts at 0, station 2 starts at 1.5 seconds, station 3 starts at 3 seconds, and station 4 at 4.5 and then repeats. I have written the program for one station. Should I just copy the same program 4 times and use a timer to sequence the stations? Or should I use a drum sequencer? The drum seems simpler but I am not familiar with them and am not sure if they have drawbacks. THANKS!

Your description is a little unclear. Let me ask some questions.
Do the 4 station use the same 4 outputs? Or are there 16 outputs - 4 for each station? Or perhaps each station has only 1 output dedicated to it?
When you note a 'program' for a station, does a station complete its program in 1.5 seconds or does it take 6 seconds, offset by 1.5 seconds from the previous. This implies a separate set of outputs.
Can you post your 20 line program? It may help use help you.

Pardon my lack of details. We are cycle testing parts, 4 at a time. There are 4 different stations and 4 different pnuematic outputs per station; 16 total. Each cycle lasts about 4.0 seconds. The start times of the cycles are staggered by 1.5 seconds. Cannot post the program right now. Thanks!
