lon to jace to modbus

Can any one give me any heads up on the gotchas in using a jace to provide lon points to a mobdus network? Thanks in advance!

AX or R2 ?

We've done it with R2 and modbus TCP Slave.
Be sure to get the licence installed (modbusTCPSlave)
Install the modbus service inside the station
Create a folder related to modbus (ModBusTCPSlaveNetwork)
Add a Modbus SlaveDevice (to wich you want to talk)
Create all the points you want to send inside that device
Link the information you want to those points.

A detailed procedure cand be found in : ModbusIntegrationRef.pdf
They explain better than me ! :)

In AX, will have to find someone else... sorry.

Good luck

Hi ctremblay, thanks for the response. I'm using ax. where is that pdf file you mentioned located? I'm studying the Niagara modbus guide now but any reference material I can get ahold of will be appreciated! we're not using tcp, I've started my station as a modbus slave, as I'm only using it to read room temps and write setpoints to/from
xl-10's, (all cvahu's) then serve the data to an amx panel using modbus. The amx sends setpoints and receives room temps.

The document was part of the R2 installation...
It won't help you in AX...

But did you tried to browse the www.niagara-central.com web site. It's dedicated to Tridium platform, maybe you could find more information about that specific problem.

Thanks ctremblay for the tip. I did go to niagara-central and look around. That's where I found the modbus guide I have. It's good reading and I believe it'll help me get the job done. I was hoping to get some insight to the modbus thing with this post. I am glad to here that your R2 integration went well. You've given me hope for the outcome of my AX project.
