PAC Suggestions. I have small project for a continuous process with a very tight budget that does not allow the luxury of going to a full scale DCS of the majors (Honeywell, Emerson, etc). This is for small pilot plant for a lab with following IO count and loop count.
Controllers: 15 (Mostly single loops, 2 Cascade and 1 Ratio control)
Analog Inputs: 32 (Includes indicators and ai for controllers)
Analog Outputs: 15 (Includes HIC and output of controllers)
Digital Outputs: 5
Digital Inputs: 10
I'm exploring the option of using a PAC for this and communicate via OPC to the HMI of our choice.
I've seen the Opto 22 SnapPAC, AB CompactLogic, Toyo (automation direct) DL205, etc...
Any experiences with this kind of small project with a DCS type of requirements, using PAC, PLC, PC based controls is appreciated.
