Not just within the realm of ADC PLCs, but even against some of the "larger" vendors. This comes from customers who are familiar with all of them, not just DL customers.
Absolutely. I've used just about everything. AB PLC-5, SLC-100, SLC 500, Control Logix, Compact Logix, all the Siemens generations, TI 5x0/5x5, Omron, GE Fanuc, Idec, Mitsubishi, Panasonic, Eagle Signal, etc. in addition to the Koyo stuff, and still can and do.
But....when the decision's up to me, right now it's either Do-More or Siemens S7. Do-More is feature competitive with the top players in the market. Model X might have some feature you lack, but some other feature you have and they don't. You guys are on par feature-wise at a fraction of the cost. You deserve to be very proud of what you've done with DM.
