Line Control
Line control is a short-circuit and line break monitoring system (e.g., E-Stop inputs)
which can be configured for the GuardPLC system. The example below shows 2
pulse test sources connected to the digital inputs (DI) of the same system. As a
result, the connections to the digital inputs (DI) are monitored.
