Hi René.
We already did that. Furthermore, We installed two 110 ohm resistors at the
end of the RX buses (I mean, one of them at the end of the RX bus of the
DCS, and the other one at the end of the RX bus of the Trisen)
Any other recommendation?
Regards,
René.

Hello René,
Please make sure that the RS-232 related switches, when using RS-422 (!!),
as written in B0700AH, rev. L, top of page 30, are set as described there.
If not (yet), please do so and see if it fixes your problem. If already
taken care of, let us know.

Subject: [foxboro] FBM230 and Trisen 310
Hi all.
We are communicating many kinds of equipments with the I/A using Modbus
serial.
We have Bently Nevada, Enraf, Omni, Hima, FSC, CCC, Woodward, Trisen (160
and 310), etc.
All the systems look good, except the TS310.
We have some strange behavior with 3 TS310 connected to the FBM230s, one of
them are directly connected to one serial port, the other two are in a
multidroop connection to other port. The TS310 has a RS422 port.
Sometimes the communications are good, and then goes bad; sometimes the
problem is fixed disabling the port in the DCS, sometimes the communication
failure begins after a IACC download, sometimes the communications are good
many hour, sometimes remains blinking... there had not been possible to
isolate the issue.
Any recommendation, note, trick, or knowledge (anything!!!) to fix this
problem?
Maybe there is an issue about RS422? This is the only one equipment using
this kind of port, the rest are RS485 and RS232.
Kind regards,
Saludos,
Rene Morales H.
