I'm looking into modernising an alfa laval control system. My preference would be to use Allen Bradley hardware. I have used 1734 Point IO in the past with a CPX L32E processor but it was on a much smaller system (~200 IO).
For CPU I think I'd like to go with the latest CLX, or 2 for that matter, with a redundant setup. Are the latest processor's all L7 and thus require Studio 5000 to program them, or are there recent L6 processers, requring Logix5K?
For IO, I read this on the AB website "Up to eight modules per assembly, for a maximum of 128 I/O" which was new to me. For this project I have 619DI, 637DO, some AI, AO, level's and counters. Does that mean for the DIO I would need at least 10 AENT modules? Or can I get more than 128IO per rack by using for example a 1734-FPD? I will need to look at the wiring of the level sensors to see if I can rewire them for DI cards. Are there any 1734 counter cards? Is there a better system for this amount of IO than Point IO?
