Digital Input Detector Process
About the Digital Input Detector Process
The Digital Input Detector process monitors digital input signals. When any (or
all) of the monitored signals are received, the process ends and generates a done
signal. The done signal from this process is used to trigger other processes.
When you define a Digital Input Detector process, you define the digital inputs
you want to monitor, the required signal state, the trigger mode, how messages
are logged, and what action, if any, you want the process to perform when it
receives a monitored signal.
You must know what is connected to each digital input and what type of input is
expected. See the Cabling chapter in the MTS 793 Controller Hardware manual
for information about digital input connections.
How to set signal
options
With the Options list (on the Input Table tab), you can specify what input signal
state is required to trigger the detector process.
The following states are supported:
I TEM D ESCRIPTION
None Disables the input.
High/Low Detects transitions from a logic high state to a
logic low state.
Low/High Detects transitions from a logic low state to a
logic high state.
Either Detects any transition from high-to-low or low-
to-high.
Channel Low Detects the logic low state.
Channel High Detects the logic high state.
