2PULSE
5.4 Modes and Functions
Diagnostic Message
If a short circuit occurs in the encoder supply or in the digital output, the 2PULSE generates
a diagnostic message for the connected CPU/master. You must enable the "Group
diagnostics" parameter in this case.
Note
Diagnostic messages provide you the information that an error has occurred in one or both
channels of the 2PULSE. You can evaluate the diagnostics with STEP 7.
The diagnostic record DS1 only contains the information for Channel 0. However, a
diagnostic interrupt is also triggered at errors in Channel 1. The feedback signals provide
detailed information about the occurring errors from both channels. Evaluate the feedback
interface in new user programs (see below).

Meaning
When group diagnostics is
enabled, the 2PULSE
generates a diagnostic
message for the
CPU/master.
The 2PULSE detects a short
circuit of the digital outputs
when "Diagnostics DO" =
On.
Meaning
Indicates a parameter
assignment error.
Indicates a pulse output error.
Indicates a short circuit of the
encoder supply.
Indicates a short circuit of the
digital output DO.
