The modules have learned new languages as BACnet/IP and Modbus/TCP have become a standard in refrigeration engineering.
Güntner, a German manufacturer of refrigeration equipment, has updated its communication modules with in-house-developed industrial Ethernet communication protocols.
The communication modules are available for GMM (Güntner Motor Management) controllers and GHM (Güntner Hydro Management) controllers, which enable users of fans and condensers to read and change parameters affecting performance. The communication modules “can be considered the interpreters ensuring the communication between controllers and superordinate systems,” said Güntner in a statement.
For example, the GCM WiFi Module can connect the GMM control unit to a WiFi or LAN network.
Due to increasing demands on the capacity of transfer technology, the "interpreters" had to learn additional "languages" as industrial Ethernet protocols such as BACnet/IP and Modbus/TCP have become a standard in refrigeration engineering, said Güntner.
“Thanks to our development and introduction of the BACnet/IP and Modbus/TCP communication protocols, the WiFi Modules for the GMM and GHM controllers meet all the requirements placed on today's refrigeration engineering,” the company said. Previous models can also be equipped with the new communication protocols via a software update.
Additional settings regarding BACnet, Modbus and the IP address can now be made via web browser mode; for instance, the bus communication Modbus/BACnet and its specific settings can be activated via the "settings" menu item
Previous functions of the GCM WiFi Module are also available when using the BACnet/IP and Modbus/TCP communication protocols. In addition to the bus communication, users can also access unit information and settings using an app, a web browser and the remote access when connected via a VPN tunnel.
