I have a project where I have modbus points coming from a PLC. I need to display those points on an HMI and forward them to a BAS system via BACnet. I think the cmtx series panel could be a great solution. Is it possible to use this panel to write values as a BACnet server? I see that it is an option in Easybuilder. I was able to make tags, but I have been unable to map values to them. Please let me know what to do and if this is possible.
A cMT X series HMI can operate as a BACnet/IP client or server or BACnet/MSTP master or slave. The drivers with the label “server” allow the HMI to operate as a server and all other drivers will allow the HMI to function as a master or client.
To map values they will need to use a macro and map the values to the “presentValue” property of their BACnet objects. A BACnet object (tag) has many properties and this is what is used to hold the current value.
