4 Existing PROFIBUS networks: PROFIBUS network baud rates greater than
or equal to 500 kBaud are recommended to obtain a < 300 ms switchover
time, based on an average processor scan time of 100 ms. For example, the
switchover time for a network running 8 slaves utilizing 700 words input cyclic
data and 700 words output cyclic data running at 500 kBaud with a processor
scan time of 100 ms is around 218 ms. Please note Hot Standby units will
increase the network token time as much as double because of two Masters
communicating on the network.
5 Module configuration network: The module requires Ethernet connectivity
to operate properly. The modules use UDP messaging between each other to
back up data in status registers used by the processor logic files to determine
switchover conditions in the event PROFIBUS FDL ping messages fail (cut-
cable).
9.1.1 Hot Standby Support
The module provides support for 140CPU6716000 Hot Standby processor with
Unity Pro programming software. Look for the HSBY (Hot Standby) icon
for
special notes relating to the support and configuration of the module.
HSBY Note: For detailed understanding of HSBY specification, refer to the Hot Standby
Addendum.
