My opinion is that ControlLogix is far better than S7-300 in certain aspects. In other aspects S7-300 is better than ControlLogix I think. By answering in such a brief manner I only wanted to stir up things a bit, but it is far more complicated than this.abspaston said:what is your opinion jvdcande i wana somehow same becuase of price is important
This is about the most sane remark that can be made in this situation. And yes, I agree with OZEE that most probably, if you turn to AB to replace an S7-300, the choice will be CompactLogix and not ControlLogix. This will certainly be the case if the price is a key element for making the selection.OZEE said:Instead of asking for the equivalent model, give us the project requirements and we can help specify it.
I didnt notice this post before. Still, it is not enough information.thanks a lot peter.i used s7-300 cpu 312c.could u tell me which model i useMicroLogix 1000 or others
It is "similar". I/O modules links each other, without there being a physical "rack". The native i/o count is 16 digital inputs per module. But 32 channel modules exist. Just like S7-300.u say that the # i/o of campactlogix is as enough as s7_300?
