SNMP to Modbus RTU Gateway || SNMP to Modbus RTU Conversion
ProtoConvert recommends the FieldServer gateway for your SNMP protocol conversion requirements. We configure and sell FieldServer gateways. We will help you find the right solution for your requirement and support you with the configuration and commissioning. 
This gateway can read SNMP data from your SNMP devices and publish it as Modbus RTU data.

It can also write to the SNMP devices.

This gateway can also do the reverse, read Modbus RTU data and publish it as SNMP data.

It can also write to the Modbus RTU devices.

In summary, this gateway can act as:

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

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

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

Server/Slave on the Modbus RTU network: The gateway can be configured to be a server of data values, hence another Modbus RTU 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
