1.2. GWC: description
GWC system has been designed to accomplish two main functions:
• Communication protocol converter/adapter (gateway)
• Programmable I/O device
The communication protocol converter/adapter function allows different field
buses – such as CanOpen, DeviceNet, ProfiBus, ModeBus, and in the future
Ethernet, to be handled/interfaced.
The programmable I/O device function allows user to write an automation
procedure that will be executed by the GWC device.
Such automation procedure can interface both digital and analog I/Os available
on the GWC device.
Both functions could coexist on the same device, allowing user a whole range of
possibilities to automate an industrial process.
GWC device is designed to guarantee enforceability of EN61800-3 and 60204-1
rules: to satisfy such rules user must guarantee connections characteristics
compliant with EMC immunity and emission, such as a ground connection, a
correct installation and a power supply filter.
