DNET Module
Summarize
DNET makes SG2, which doesn’t have the ability of DeviceNet, to work in DeviceNet network. At DeviceNet
side, DNET is a GROUP 2 ONLY equipment, slave equipment in this network. At PLC side, DNET communicate
with SG2 through SG2 COMM. Port, it is point-to-point communication equipment.
DNET is together with SG2 as one slave equipment in DeviceNet network.
