7.1. Control by the External Control Device
The following 2 methods are used to control the DP-SP3 from the external control device.
Functions to be controlled differ depending on each method.
7.1.1. Method of direct control
This example shows a method to control the DP-SP3 by directly connecting the external device’s contact
outputs to the DP-SP3 unit’s contact inputs.
