Can a Charm discrete output be configured as a Normally Closed contact so that it can be utilized in the STOP circuitry of the motor control?
Out client has a 2 output motor control wiring for DCS. The motor control circuit has normally open DO Momentary for Start command in parallel with local start PB and holding contact once motor is pulled in.
Motor also has a normally closed DO momentary STOP in series with local NC stop PB.
How can this be done in DeltaV using Charms I/O?
