Hello List, At our plant we are considering a boiler control upgrade and the BCS =3D would be upgraded to the Fox I/A. However, the BMS is an AB PLC5 system =3D and the decision to be made is whether to replace it and implement in = =3D I/A system or use an integrator. Does anyone have experiences with this sort of integration? What are the pros/cons. Cost would be a factor in the decision making process - however, =3D reliability is key.
