why should i choose AC500 and why not others,what are its attractive features which make it differen
We have to compare ABB PLCs with other brands step by step, but it take so long time.
Instead of it, i can list some basic features, which AC500 has.
The pros according to me:
*Compact and Eco series CPU's has builtin communication protocols such as Mofbus RTU.For example this builtin feature is not supported by Siemens.
*If you use ethernet CPU, also you have Modbus TCP protocol. For example this builtin feature is not supported by Siemens.
*For an expansion modules, AC500 PLCs use built-in CS31 protocol, no more hardware and software licences are not needed at CPU side.
*Cheaper than other brand CPUs.(Price is depend on my country, maybe at your country this is not applicable.)
The cons according to me:
*AC500 PLCs dont have its own software, prefer to use Codesys.
*AC500 PLCs dont have it own SCADA software, Divigis500 is Freelance 800F Clone.
Hope my opinion helps you.
