Display BACnet on UniStream

[Guest Hervé]

hello, I would like to know how to display the BACnet on unilogic.
I manage to make the link with an automaton but after I am blocked to visualize it on the supervison.

Thank's

Hello,

The GW-BAC1 is an external, high performance Building Automation multi-protocol gateway that has been preprogrammed for enabling Unitronics products to various building automation protocols. These protocols include BACnet MS/TP and BACnet/IP. Configuration for the various protocols is done via Unitronics configuration tool UniBACnet Configurator.

 

To configure it you have the UniBACnet configurator. this configurator is a tool provided Unitronics that allows the user to create the configuration file for the GW-BAC1 easily. Once created, the configuration file should be downloaded to the GW-BAC1 in order to enable it to communicate with the Unitronics PLC. The UniBACnet configurator can be launched from both the VisiLogic and UniLogic programing applications Tools menu. This tool will configure the BACnet getaway as BACnet master and modbus Slave. If you wish to have the getaway act as BACnet slave and modbus master the configuration file should be change manualy before downloading it to the device.

 

The RS485 connection is a strait forward RS485 connection between the PLC and the getaway.

You may also connect the PLC via Ethernet port.

 

The Getaway supports Modbus RTU and Modbus Ethernet and Bacnet MS/TP and Bacnet IP.

You may have any combination of them.

I have attached some examples to use with UniStream PLCs.

Do you have an example project where the PLC is the slave/server? We have a Crestron that's supposed to control us via BACnet.

I tried to manually modify the config file to swap the roles but it didn't work.

Which sections would I swap here?

In the provided example "unistream_070_Bacnet_TCP", there's a global of type "Modbus Remote Slave". When I try to add another global, "Modbus Remote Slave" doesn't appear as a type option. Since my PLC is going to be the slave, should there be a type "Modbus Remote Master"?
