3.7.1 Introduction
8-channel digital input with 2-channel timestamp
The EPP1258 EtherCAT P Box with digital inputs acquires the fast binary control signals from the process
level and transmits them, in an electrically isolated form, to the controller.
The signals are furnished with a timestamp that identifies the time of the last edge change with a resolution
of 1 ns. This technology enables signals to be traced exactly over time and synchronised with the distributed
clocks across the system. With this technology, machine-wide parallel hardware wiring of digital inputs or
encoder signals for synchronisation purposes is often no longer required. In this way, the EPP1258 enables
responses with equidistant time intervals, largely independent of the bus cycle time.
