We are in the process of replacing a L&N DCS with a Foxboro I/A DCS.=20
-------------------------------------------------------------------------=

We are considering using the "GDEV" block for all our open/close valves=20
(single coil + dual coil solenoid & motor actuated) as well as all the=20
motor start/stop. (instead of using blocks: VLV, MOVLV, MTR)
Who out there has standardized on the "GDEV" block for on/off open/close =
control?
What have you learnt by doing this? What are the advantages? What are =
the disadvantages?

Another method our Foxboro Engineers have recommended to us is to use =
the "CALC" block=20
(instead of GDEV, VLV, MOVLV, MTR)
Has anyone gone this route?
