If inputs with the same function contradict each other, there is
a selection based on the following priority:
1. Inputs from internal I/Os
2. Inputs of an I/O expansion/CPI module
3. Inputs from EasyIP
Trigger signal" input
The trigger signal" input is for starting and stopping the test
operation. The mode of operation, signal detection and the
signal curve depend on the selected evaluation mode.
See also chapter 4.8.
Accept input signal" input
The accept input signal" tells the device to read normal in
puts. The accept input signal" is detected with edge control
and is only valid when the output ready for operation" out
puts logical 1. In order to reread inputs, the signal, then,
must first be reset.
As long as inputs are read and processed (e. g. loading of a
new test program), the output ready for operation" is at
logical 0. During this time, no parts can be tested (the trigger
signal is not valid as long as the output ready for operation"
is at logical 0).
As soon as the inputs have been completely processed, the
ready for operation" output goes back to logical 1. Trigger
signals for a test are now accepted.
