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. 
• 
Sync mode: 
Output (control) data values are held constant within the PBDP-
110 until the next “sync” command or an “unsync” command is 
received.  Used primarily for synchronized control of multiple 
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. 
• 
1 green LED on each of the Channel A and Channel B drive connectors, 
which indicate that the port is receiving power from the corresponding drive.
