Modbus Integration Solutions

Chipkin has Modbus solutions for almost every situation. We are experts in Modbus RTU/TCP communication and carry a wide variety of Modbus products:


The Modbus RTU driver allows the FieldServer to transfer data to and from devices over either RS-232 or RS-485 using Modbus RTU protocol. The FieldServer is capable of being used as a port expander.

The FieldServer can emulate either a Server or Client. The FieldServer is capable of supporting devices that use two Modbus Registers to transfer IEEE floating point format.
