Important Program and Operator Control Transfer Considerations
The first two rungs of the E3Plus_CommsAux AOI handle the transfer of control from the Logix program (Program
Control) to the faceplate (Operator Control). These are the two Operator Control rungs. It is important to understand
how these rungs operate so your desired program to operator and operator to program control transfers are achieved.
For example, these rungs enable the Program or Operator Control of the intended E3 Plus Overload Relay. Command
requests (Cmd) can be initiated from either the Logix Programs (ProgOperReq) or the FactoryTalk View ME E3 Plus
Faceplate (OperOperReq).
EXAMPLE To enable Operator Control for a device associated with ‘Motor_1’ AOI instance, a rung is added to the Logix MainRoutine with
specific input conditions driving an output instruction with the tag name ‘Motor_1.Cmd_ProgOperReq’. Likewise, a pushbutton in
an RSView ME/SE Faceplate is added with a value tag name of ‘#1.Cmd_OperOperReq’ with the #1 parameter for that faceplate
display associated with ‘Motor_1’ tag.
A ‘Motor_1.Cmd_ProgToOperPermissive’ must also be included in the Logix Program to control whether Program to Operator
Control transfer requests are allowed or acted upon. A tag value of 1 permits the associated control transfer requests. A value of 0
prevents the associated control transfer requests.
