Siemens vs Allan Bradley

[plcking]

Guys, I have to reveal to you a revalation.

I've been working with AB for as long as I remember but my last project was Siemens. Of course because I am a PLC king I accepted the job even while knowing nothing about the siemens system.
Fortunately, they paid me far more than it was worth, but thats another story.

Anyway, to my revalation.

Siemens is amazing! I cannot believe I have been held back so long by the inferior allan bradley software. Siemens enables me to be a real PLC programmer and means I can make the machine do what I truly am capable of making it do.

I wonder how many of you are also siemens programmers? Did you find it to be an amazing tool for your armory?

Welcome to the land of enlightenment.

Although I do have to say the latest RS Logix5000 has made a significant step forward. Plus when are Siemens going to give us a compute function and why can't they sort their words from their bytes

Why should they sort them.
Siemens gives you the option to write on words/byte/bits and yes you can write even on a single bit in an assigned word. There are applications out there where it makes sence, so if you know what you are doing there is no reason for siemens to not let you do it ! Other Programming languages like Delphi or C++ are totally open in these things as well.

Both controllers have there pro and cons. From my experience I would say Siemens give you more options where AllenBradley gives you more safety in not making errors. I am personally write all my Siemens Stuff either in SCl or STL, and I do not like the way AB implemented the STL Language.

I am working with SIEMENS plc,AB Rockwell plc,Mitsubishi plc,GE plc,Omron plc,Schneider plc almost every day.

I think SIEMENS make easy thing difficult,Perhaps this can be reflected in the clever German.

AB more flexible, but the lack of rules
