Likewise it is quite usefull when having the DCS control devices it is
otherwise not fast enough to effectively control, refiner plate movement
in a paper mill,for example.
Lots of maintanance folks still like the ladders; they understand them right
out of the box. Relative isolation of a PLC FBM improves reliability and
reduces likelyhood of errors elsewhere impacting that control device. This
thing certainly has it's place in a DCS.
I would argue for improved communications and configuration twixt FBM and CP
and some ladder function improvements. Such add number transfers and limited
numeric PLB functions. Such as a somewhat more slick ladder editor. They
never integrated very well with FoxCAE. Is there integration with IACC?
Can I "can" a motor controller which includes HMI, Block and PLB functions
and drop multiple instances into an IA system data base? Would be nice.
