Hardy Process Solutions (United States) - PROFINET is a Fieldbus protocol compatible with Siemens PLCs that is widely used in Europe, Asia and Latin America and is increasing in popularity in the United States.

The Hardy implementation supports two-port PROFINET with MRP (Media Redundancy Protocol), which enables the HI 4050+ to join into a ring topology network (Conformance Class B or CC-B). The card installs in the communications options slot and automatically scans for PROFINET networks.

Simultaneously, Hardy has released a GDSML for PROFINET users for ease of configuration. A GSDML file is a readable ASCII text file that contains the Device ID and both general and device-specific weighing commands communication and PROFINET network configuration.
