Overview
The IPG26-D2T3S-D2 is an easy-to-configure and powerful gateway that connects Modbus RTU devices and networks to PROFINET network systems. The gateway enables bidirectional data exchange, allowing existing low-cost Modbus RTU devices to be integrated into PROFINET network systems while also providing data from PROFINET to Modbus RTU devices. This device has been maturely applied in industrial scenarios supporting Modbus RTU interfaces, such as frequency converters, servo drives, intelligent field measurement devices, instruments, PLCs, DCS and FCS.
