What are the dif. between a Siemens PLC and an Allen Bradley PLC?

Answer 1

The A_B ones have better programming software (more intuitive to use and more obvious which contacts are true). The A-B ones are also a better physical package in terms of robustness and clearer indicator lamps for I/O status.

Answer 2

I work in the circuit board industry, Siemens is the most popular. As far as what the other guy said about support? I never had problems. Allen Bradley is good too, but Siemens is known as #1

Answer 3

Allen Bradley:
simple, sturdy, good support, does the job (expensive)

Siemens:
complex, cheap, bad support, does the job and gives you a headache (expensive)

very simple, sturdy, good support, does the job and less expensive.

Edit:

Allen Bradley is concentrated in the North American market. Siemens is world-wide, so obviously it dominates in foreign region. But that is due to their intense marketing effort, not the quality of the product.
