Goals and Symptoms


Network issues may be experienced after performing a ProWORX Netscan with an XBTF installed (TSXMBP100)

====================

=> Concerned issues :
Using ProWORX Netscan:
Scan a Modbus+ network that contains one or more XBTF(s) equipped with MBP100 cards by means of:
1) The PC communicating to the PLC via Modbus and connecting to the Modbus Plus network via bridge mode.
2) Using Netscan on a network through a BP85 bridge that contains one or more XBTF(s) equipped with MBP100 cards.

----------------------------------

=> Symptoms :
Issues that may be experienced are :
1) When bridging from Modbus to Modbus Plus: Once the XBTF is querried the Netscan will slow down. After the Netscan is completed Modbus communication will appear to be locked up.
2) When bridging to another Modbus Plus network via a BP85: The Data Slave path will be held. If 8 Netscans are performed all 8 Data Save paths will be in use and no communication will occur in that direction.

=> Recovery :
Once the issue has been experienced the methods to restore are:
1) When bridging from Modbus to Modbus Plus: Power cycle of the PLC.
2) When bridging to another Modbus Plus network via a BP85: Power cycle of the XBTF or the BP85.
