Ethernet Protocol - ADF Web AXIS HD67576-A1 User Manual

Industrial Electronic Devices

ETHERNET PROTOCOL:

The communiocation is made through UDP frames.
The frame that the HD67576 sends is composed like follow:
(DLR + 7) ÷ (DLR + CLP + 6)
(DLR + CLP + 8) ÷ (DLR + CLP + DLW + 7)
DLR + CLP + DLW + 8
DLR + CLP + DLW + 9
If the "DLR" and/or "DLW" has got the value 0x00 there are no data to read/write.
The "Data OUT" are the same that the HD67576-A1 receives with the frame sended by the companion.
The frame that the HD67576 expects is composed like the follow:
(DLR + 7) ÷ (DLR + CLP + 6)
(DLR + CLP + 8) ÷ (DLR + CLP + DLW + 7)
DLR + CLP + DLW + 8
(DLR + CLP + DLW + 9) ÷ (DLR + CLP + DLW + CLD + 8)
DLR + CLP + DLW + CLD + 9
