Hi everyone.
I've got a new design that will require a PLC. I'm currently deciding between two:
1. AD DL06
2. Schneider Twido
The application is an electronically-controlled hydraulic gangway that will move disabled sailors from the pier down to the float. The safety systems are done by separate safety controllers.
The PLC will be in a case, but will be subject to temperatures of -20 to +40 (Celcius). Those are the record temperatures for this area. The case temperature could go even hotter on a hot day with the sun beating down on it. I have to put in a little strip heater and a fan into the case to make sure the PLC stays within the operating temperature.
I require 26 inputs and 18 outputs, which is why I'm looking at these two. (The Twido Extreme doesn't have enough I/O) I'd originally purchased an Omron Zen, but that didn't have enough ports. (By the way, I have an Omron Zen with expansion module for sale.)
I like the AD. The programming software seems easier to use, and the state diagram model looks really, really, easy. I've paid a lot more for programming environments that were a lot worse. (Embedded C) On the other hand, the Twido rep offered to spend a few hours with me to boost me over the learning curve.
What would be a good choice here? I'm new to PLC programming (but not programming in general) so I don't want to get something so ridiculously powerful that I end up shooting myself in the foot.
The price point is comparable. I'm looking at about $1000 for the DL06 with the expansion, software, and cables*, and the Twido is about $800 for the same.
Thank you for your input. I appreciate the help.
*Yes, I could make the cables, but it's cheaper to just buy it.
