Global Control Functions
•
Freeze mode: Input (monitor) data values are held constant within the PBDP-110
until the next “freeze” command or an “unfreeze” command is
received. Used primarily for synchronized monitoring of multiple
Profibus nodes.

Profibus nodes.
•
Clear_Data:
All output (control) data values are cleared to “0”.
Network Watchdog
A network watchdog function is always operating within the PBDP-110. In the event
of a disconnection from the Profibus network or loss of the network master, the
PBDP-110 can automatically switch any attached drives over to local control (if
selected at time of unit commissioning).

Indicators
•
1 green LED is provided to indicate when the PBDP-110 has achieved the
DATA_EXCHANGE state with the Profibus network master. This serves as a
convenient indicator that the Profibus master and PBDP-110 are configured
properly and are exchanging data.

•
1 green LED on the MMI interface port. The context is application-specific,
but under normal operation blinks at a 0.5Hz rate as a “heartbeat” indicator.
Also indicates data transfer when used with the Flashloader programming
utility.
