Industrial Motor Controls, 1.a. Where should the shield for the wire between the D/A module and the motor speed controller be connected? A. At the D/A module B. At the PLC C. At the motor speed controller D. At the auxiliary power supply 1.b. If the battery backup fails on a PLC, what will occur? A. The PLC will shut down due to loss of memory as soon as battery voltage drops below a certain level. B. The PLC will illuminate the battery LED and extinguish the RUN LED. C. The PLC will operate normally; however, if power is lost, memory will be lost. D. The PLC may have logic solving errors until the battery is replaced.
