Honeywell HC-900 and Labview

2 posts in this topic

Can you pull data from an Honeywell HC-900 and view it in labview? For example viewing the temperature of a furnace hooked up to the HC-900 in a graph via labview.

Honeywell’s Hc900 has both Modbus Master/client and Modbus Slave/server functionality as standard features in its CPU.   Modbus is implemented with Function Blocks.  Tags are used to identify the relevant data.  There is default mapping of slave data to Modbus address registers or a custom mapping option.

I’ve seen theads on internet fora like this one regarding Labview having Modbus, but I do not recall the details.

So, yes, NI’s Labview should talk Modbus to the HC-900.
