GPIB to Modbus Interface Board from ICS Electronics
January 14, 2009
The Model 4829A GPIB-to-Modbus interface board from ICS Electronics, Pleasanton, CA, controls slave Modbus devices that use RS-422 or RS-485 signals from the GPIB bus. The board handles all message formatting and checking required to communicate with devices that use the Modbus RTU protocol. The GPIB interface lets you send simple ASCII messages on the GPIB bus to control and query slave Modbus RTU devices. The RS-232 interface has an RS-232 to RS-422/RS-485 converter function so that an RS-232 data source can control the RS-422/RS-485 Modbus slave devices. The board lets you add a GPIB interface to temperature chambers, ovens, and other industrial equipment that uses a Modbus controller.
