A gateway is a network node that bridges different communication protocols. The gateway thus creates a communication path for data from different systems.

An advanced multi-gateway, such as Squid.Link from Develco Products, can simultaneously function as a link between a number of protocols.

Develco has among other things Contributed to the development of Squid.Link as well as the development of a gateway to Grundfos in the form of the G501 Connect Box solution, with several connectivity options for monitoring different Grundfos pump systems.
