Modbus / Modbus TCP

Modbus is a simple networking protocol that allows for control and data transfer between two industrial devices. There are two types of Modbus, Modbus serial and Modbus TCP. Modbus Serial uses RS232 and RS422/RS485 while Modbus TCP uses Ethernet. Both protocols are the same except for the additional information needed to handle the physical layer. Grid Connect provides a great selection of industry leading Modbus and Modbus TCP products. Our Sales and Engineering staff are experts in Modbus and can help you to find the Modbus solution that works best for your application.
