Hi all,
I'm new to Siemens and I'm trying to find the Siemens equivalent for a Micrologix 1400.
In addition to the Ethernet port and online editing, I would like a recommendation based on hands on experience.
Please also consider not suggesting a PLC that would be obsolete in the coming few years.

Thank you!

An S7-1200 is the same concept (brick with integrated IO, and with some expansion ability) and same size, and can do what an ML1400 can do.

Thank you for the recommendation.
I don't care much if I'm not getting a brick, as long as I get a similar set of features (including the Ethernet port), and the price is in the Micrologix 1400 range or lower.
 
I second the S7-1200. Similar price range, similar format, similar features. You could even say it's one step ahead of the ML1400 because it uses the most current Siemens software package, whereas the ML1400 uses an older AB software package (still supported and "current", but no more development is going into it, and it's not the future direction of AB software).

micrologix 1400 is a pretty powerful little PLC , Software maybe older but does the job and the ladder in AB is far easier to work with, just my opinion

Oh, absolutely, the ML1400 is still a great workhorse. Truth be told, I'd use a ML1400 over an S7-1200 wherever I could, but that's purely because I'm much better at AB than Siemens - not because one is inherently superior to the other.

In this case, though, it's a moot point because the OP has to use Siemens.

S7-1200 is about same price, I/O cards can be added , software is not cheap either
 
I have a list price of ~630€ but I can get more discount on a ML1400 than I can on Siemens. The ML1400 has 20IN 12OUT.

Curious, what does ML1400 cost ?
For comparison a Siemens 1214C with 14DI-10DO-2AI is list price ~330 €.

I think it ranges a lot... but I think the two we have are close, I would say they are both great when it comes to hardware, the software is another subject, TIA is getting better but RSLogix was a easy platform to learn

Speaking about prices, and I know you will say I'll be missing I/Os, why not getting a SIMATIC S7-1500, CPU 1511 for about the same price of a S7-1200?
What would be the pros and the cons of doing that?
Let me start the list.
Cons:
1. You are no getting the brick with the I/Os.
2...

The S7 1500 is about $2,000.00 for just the CPU then you add the I/O so its all about the price when you have a budget

That is an advantage IMO ;)

What speaks for selecting an S7-1511 even if it is overkill for your current task, is that in case you in the future need to create bigger control systems, then you will not have to change platform (*).
Also, there are many advantages with going for a slice-based IO-module system instead of the the fixed IO plus expansion modules as in a ML1400 or S7-1200.

*: Swiching back and forth between S7-1200 and S7-1500 is not so bad as switching between say ML1400 and CompactLogix. Code can be shared without modification between S7-1200 and S7-1500, if not 100% then 99%.

If you go for S7-1500 you will also need STEP7 PRO, not just STEP7 BASIC. So it is definitely a bigger expense.
