4.2 Configuration of the EP1518
4.2.1 Basic Function Principles
The EP1518 EtherCAT Box has 8 digital inputs. Of these, inputs 0, 1 and 2 as well as 4, 5 and 6 can each
be used for one counter. The states of the individual inputs are always illustrated in the process image,
irrespective of their use.

2 up/down counters (32-
bit) 2 2 Single pulses are counted at the counter
inputs.
The gate input or the software gate enables
the counter.
The count direction is specified via CoE.

counter - 8 digital inputs:
Filter for inputs 0 and 4 permanently set to
150 µs.
The filter setting for the other inputs is
configurable by software.
The GATE and Up/Down inputs can be converted to standard inputs.
Counting mode
The following settings for GATE and Up/Down can be combined and apply independently to each counter.
Counting mode with standard setting (up counter)
In the delivery state the Counter Value is incremented on each rising edge. The count direction is up.
The counter is disabled by applying a high level to the GATE input or by setting the Inhibit Counters bit.
