2 digital inputs with time stamp function − EPM−S207

By integration of the GSE file VI010C19.gse you can specify all counter parameters via a
hardware configuration.

The following functions can be parameterised:

Functions

Description

Input delay

For example, signal peaks can be filtered in the event of an unclean input signal.

Edge selection

Specification of signal edge for input signal to produce a time stamp entry.

Status of inputs:the status of the inputs after the edge change is saved here. Parameters
can be set for the following variants by incorporating the GSD file LE010C3A.gsd:

Running number: the "running number" (RN) is a consecutive number between 0 ... 127,
which always starts afresh from 0. The "running number" reflects the time sequence of the
edges

Ticker value: After mains connection, a timer (

ms ticker) is started, which after 65535 ms

starts with 0 again. With every change in the encoder value the time value of the timer is
stored as a 16−bit

ms value together with the encoder value in the input area.
