Sandy,
Some suggestions for you since this seems to be a new installation;
#1 make sure you are using equivalent or higher revision of the
FBM224/FBM230/FBM231 Termination assembly below;
P0926GH rev. E (compression screw)
P0926PA rev. B (Ring Lug)
#2 Close C5 and C6 on the RS232 DIP switches, all others on A, B and C
should be Open.
#3 Use the latest Documents, B0700AH-N and B0700BG-H
#4 Use the latest driver, V2.3.4
#5 Use the latest FBM230 firmware, V1.35
#6 Use the latest FDSI configurator, V1.4
#7 With the latest driver, configure all the diagnostic counter blocks for
ECB200 and ECB201
These will help you determine the best TO= setting plus give a
wealth of information on how the interface is
performing. You could create a graphic with this information for easy
access.
#8 Determine if the RedLion is capable of Heartbeat and then determine
which of the 3 heartbeat methods to use.
#9 Kevin brought up a good point about having more than one Master on the
bus at the same time and to know what exception
codes are being returned from the PLC >> RedLion >> FBM230.
Regards,
Scott

Brian,
I have tried to put 2 second, 30 second, timeout but the problem still
persist. Once there is any break in the communication, then manually I have to
disable then enable communication from SMDH.

Sandy

Probably need to add more time to timeout, see manual for details.
Sorry to not be more help, I'm not close to any docs.
