• W0.02 is turned ON to request sending data from the Ethernet Unit. Data (100 bytes) is sent
beginning at D00000.
• W0.03 is turned ON to request receiving data from the Ethernet Unit. The data that is received
(100 bytes) is stored beginning at D01000.
• One of the bits between W1.00 and W1.03 will turn ON if an error occurs. Refer to 15-7-5 Socket
