Update.
The Boss bought me a ZEN-10C1AR-A-V2.
It is a nice little box. He also got me programming software and an interface cable.
I installed the program on another computer, Windows 7, and it installed nicely.
Very easy to use, and pretty limited. It may be because the thing is also designed so
one can program it from the front panel.
It limits me to three contacts and one coil per rung. The Timer relays have
several different modes - including TON, TOFF, and one shot. My current plan has me using one One Shot, and two TOF's.
A co-worker reminded me that I need to change 'main chain' to spur chain.
If the gods smile upon me I will have the ladder and a look at the Omron
software window. (Double click the timer contact and I get an 'Edit contact
Dialog Box' where I can select what type contact, timer, and timer parameters.)
