I hope I can give you an APROX answer "skill".
The key issue is the size of the system. Up to about $5k the SLC will be cheaper... above that the CLX will gradually become more cost effective. For large and complex systems say over 1000 I/O the CLX will win out everytime.
This is...
Gents,
I agree with techshoot that subroutine functions are easier in PLC, and ControlLogix...in fact in CLX I use create a User Defined Data type for ALL my subroutinesand simply pass one variable with all the routine data.
BUT the same technique also works for the SLC and Micro1500...just a...
I totally agree with the above comments.
1. Soft PLC's have a place in processor intesive applications where their number crunching abilty is needed and their ability to transfer data to other PC apps is unsurpassed...but any Emergency Stop or safety shutdown interlocking MUST be in a separate...
