I think the multiple outputs mapped with multiple inputs is confusing the simulator. Is this common with other PLCs? I understand the Teco units may be at the low end of the PLC spectrum and maybe that's my problem. I need a higher end PLC to do this job.

I'm wondering if it has something to do with limitations of the Teco simulator. Once the ladder circuit is designed, I started the simulator. Upon initiating input 1 , only output six activates, input 2 activates nothing, input 3 activates only output 1, input 4 only activates output 7, input 5...

I need a PLC, preferably compact, rail mounting, 24 VDC, with at least 8 discreet (digital) inputs, and 8 relay outputs. I was looking at the inexpensive TECO SG2-20VR-D. I downloaded their SG2 Client software. Designed my circuit on it, and activated the simulator. Unfortunately, it didn't work...
