Interfaces to the Control Program and Process
To execute the modes and functions, the 2PULSE has as an interface to the process of a
digital input and a digital output for each channel (DI 0, DO 0 for channel 0 and DI 1, DO1 for
channel 1).
You can modify and monitor the modes and functions with your control program using
control signals and feedback signals.
Parameters are assigned to the various modes. See the technical specifications for
programming a complete list of parameters for all modes.
You will find the following in the sections on modes and functions:
• The relevant parameters
• The control and feedback signals
The description of the modes and functions applies to both channels and the channels are
therefore not referred to separately in the description.
