EII Edge Select (ES)
The ES (Edge Select) bit selects the type of trigger that causes an Event
Interrupt. This bit allows the EII to be configured for rising edge
(off-to-on, 0-to-1) or falling edge (on-to-off, 1-to-0) signal detection. This
selection is based on the type of field device that is connected to the
controller.
The default condition is 1, which configures the EII for rising edge
operation.
EII Input Select (IS)
The IS (Input Select) parameter is used to configure each EII to a specific
input on the controller. Valid inputs are 0 to 7, which correspond to
I1:0.0/0 to I1:0.0/7.
This parameter is configured with the programming device and cannot be
changed from the control program.
