( 3 ) PARAM02: Remote Connection Number
PARAM02 specifies the remote connection number.
The following table provides the valid setting range.
Transmission Device
EtherNet/IP (263IF)
( 4 ) PARAM03: Option
PARAM03 sets options specific to each transmission device.
PARAM03 is not used for explicit messages. Setting is not necessary.
( 5 ) PARAM04: Function Code
PARAM04 sets the function code to be sent.
Explicit messages use only function code 03H.
 Usually, function code 03H is used to read the contents of holding registers. With explicit messages, however, it
does not have that function.
( 6 ) PARAM05: Data Address
PARAM05 sets the leading address of the M registers storing the explicit request message. The received explicit
response message is also stored in the same area.
The address is input as a decimal or hexadecimal value.
 Example: To set a leading address of MW01000, set 1000 (decimal) or 3E8H (hexadecimal).
The following table provides the data address setting ranges used for explicit messages.

Applicable Data
Function Code
03H
( 7 ) PARAM06: Data Size
PARAM06 sets the data size (number of bytes) for explicit request messages. When an explicit response message is
received, the data size (number of bytes) of the response message is displayed.
Do not allow the final address of the data, which is determined by the data address and data size, to exceed the valid
range of addresses.
The data size varies according to the request service code, class ID, instance ID, and attribute ID of the explicit mes-
sage. They are specific to EtherNet/IP devices. For details, contact the manufacturer of the EtherNet/IP device to be
used. The following table provides the data size setting ranges used for explicit messages.
