• This gateway can read Modbus data from your Modbus RTU devices and publish it as BACnet MSTP data.
• It can also write to the Modbus RTU devices.
• This gateway can also do the reverse, read BACnet MSTP data and publish it as Modbus RTU data.
• It can also write to the BACnet MSTP devices.

In summary, this gateway can act as:

Master on the Modbus RTU network: Hence it is capable of reading data from the various Modbus slave devices and writing data to them if required.

Slave on the Modbus RTU network: You can use the gateway in this mode if you have a Modbus RTU master on the network which would be reading data from the gateway.

Client/Master on the BACnet MSTP network: Hence it is capable of reading data from the various BACnet MSTP devices and writing data to them if required.

Server/Slave on the BACnet MSTP network: The gateway can be configured to be a server of data values, hence another BACnet MSTP client can read data from the gateway and write data into the gateway.

How to configure the FieldServer gateway?

-We will configure the gateway for you based on your requirement and support you during commissioning of the gateway, so you do not  have to worry about configuring the FieldServer gateway.

-However, it is very helpful to know how to configure the devices. All the required tools and supporting product manuals with be provided completely free of cost with your purchase.

-Configuration of the FieldServer is done using a '.csv' file. This file can be edited using any text editor (example Microsoft excel).

-In this file we need to enter information for the Client and Server side interfaces of the FieldServer. This includes but is not limited to:

                Node ids of the slave devices

                IP addresses/device address of the slave devices

                Baud rate, parity, stop bits for serial communication

                Scan rates

- And finally we need to create an internal mapping that would map each data value read on the client side to a data value on the server side.

-For detailed information on configuration please get in touch with us and review the configuration manual on top of this page
