Using EtherNet/IP
Send Length
This parameter specifies the length of the data sent from the EIP master scanner to the
scanner. The maximum number of bytes that can be sent in one message is 470 bytes.
Receive Length
This parameter specifies the largest amount of receive data the EIP master scanner host
can accept from the scanner. The maximum number of bytes that can be received in one
message is 470 bytes.
Receive Timeout
This parameter specifies the longest amount of time in milliseconds (ms) the EIP master
scanner host is willing to wait for a new message. A value of 0 is used for an immediate
timeout. When the scanner responds to the EIP master scanner, the Receive Timeout indi-
cates the number of ms that passed from the time the request was received to the when
the response is sent.
Caution: The time frame defined by this serial interface object field must be less than the
unconnected message timeout.
Caution: If the Receive Flag "Clear Before Receive" is used, see Receive Flags for proper
operation.
Receive Request Flags
The Receive Request Flags field gives the host additional controls over the serial input.
Bit (0 = LSB)
0
1-7
Flushing the input queue allows the EIP master to remove irrelevant data that was collected
by the scanner.
Caution: If the "Clear Before Receive" bit is used with a receive timeout of zero (0), the
scanner will respond with an "Object State Conflict" error. When using the "Clear Before
Receive" bit, always specify a non-zero timeout so the device will have a chance to generate
a response to any commands in the data field.
A-92
Clear Before Receive — Clear the serial input queue before
receiving new incoming data.
