Before you can set outputs (%Q and %AQ) on a BIU, you must enable outputs to it. To enable outputs to a BIU, configure a digital point on the BIU with the address %EO. When the CIMPLICITY project starts, the point at %EO will be set to FALSE (0) and outputs to the BIU are disabled. When you set %EO to TRUE (1), outputs are enabled to the BIU and can be used to control the block's outputs.
You can use any of the following CIMPLICITY functions to set %EO:
A Setpoint action on a
CimView screen.
A script that performs a setpoint
in the Basic Control Engine.
A Point Management API procedure
that performs a setpoint.
Once the %EO point is set to TRUE, outputs to the BIU may be set.
