Technical data

Slave watchdog
time:
With this parameter, you decide whether or not the
slave operates on the L2-DP bus with watchdog
monitoring ON or watchdog monitoring OFF.
The monitoring time itself is set only once in the DP
editor screen and applies to all connected DP slaves.
The watchdog monitoring on the DP slave is used to
monitor the DP master.
Each time a frame is received from the DP master, the
watchdog monitoring is restarted in the DP slave. If the
master fails, this is recognized by the DP slave after the
monitoring time elapses and the slave changes to a
safe state (for example, all outputs are reset).
User-selectable
data:
In this field (which can also be selected in the next
screen with F6 USER PAR) you can specify the
user-specific data contained in the device
documentation provided this is permitted for the DP
slave. From 0 to 235 bytes (0: none) of user assignable
data can be specified.
Output fields:
Length: Here, the length of the user-specific data entered is
displayed in bytes.
