The used evaluation mode (see chapter 4.8) defines how the
device reacts to input signals or when the test results are
output at the outputs. A higher−order controller must be pro
grammed according to the signal behaviour of the selected
evaluation mode.
4.9.1 General information about the use of inputs
There are inputs with signal function and other inputs.
Inputs with
signal function These inputs depend on the output mode, edge or status−
controlled. They are read constantly. If the signals are valid
with regard to the current operating state, the correspon
ding action is immediately executed. Inputs with signal
function include:
Trigger signal
Accept input signal
Acknowledge error signal
Other inputs These inputs are status−controlled, i.e. they react to logical 1
or logical 0. They are read only after a valid Accept inputs
signal".
Example for normal input": Test program preselection.
