Honeywell TrendView Recoders (Modbus TCP/IP) How?
Need some clues as to getting a Honeywell TrendView (MultiTrend Plus V5) recorder to communicate via Modbus TCP/IP to anything!
It would be nice to get these things to talk to our OSI PI system, however I am having huge problems pulling data out of them with the Win-Tec ModScan software.
ModScan will connect to the recorder, however can't seem to find the data at any of the suggested addresses in the Honeywell Communications manual.
Another note, the Honeywell Communications Manual dosn't give any info on Modbus TCP/IP. But the Recorder Manual gives details on how to enable it!
Please Help!
A really nice tool would be one that scans the address ranges automatically identifing them by value, size and type!
Many Thanks in Advance,
Colin Halbert

For those searching archives, a summary of Honeywell's Trendview V5 communications functionality:
Trendview V5 models had no digital communications as a standard feature.
H-W offered a free comm card with ethernet, but not always selected, so there are some recorders with no comm card.
V5 ethernet supports the recorder's internal HTTP web server and FTP to Trendserver Pro (TSP), Windows software, for transfer of saved data and setups/configs.
V5 ethernet supports Modbus/TCP (slave mode only) or Trendbus, not both, each is mutually exclusive of the other.
Trendbus is a proprietary protocol for real-time communications with TSP.
If Modbus TCP/IP Slave selected, you can still have TSP's FTP and browser functions at the same time, but not Trendbus (no realtime). The FTP function is intended to work with the FTP function in TSP software, not with generic FTP clients.
The V5 ethernet board has an RS-485 port solely for Trendbus (primarily for legacy V4 Trendbus compatability).
V5 Trendbus over RS-485 does not exclude the web server or FTP functionality on the ethernet port.
An optional Modbus RS-485 card does Modbus RTU (slave) only, it does no other comm protocols; specifically, no Trendbus over RS-485.
The RS-232 port is for a serial string of up to 35 ASCII characters for mark-on-chart functionality. Serial bar code readers generate such ASCII strings. Enabling such requires the Events option.
