Number of basic steps 161 steps
The number of FB steps integrated in the program varies depending on the CPU module used, the input/output definition, and
the setting options of GX Works3. For the setting options of GX Works3, refer to GX Works3 Operating Manual.
Processing • Turning on i_bEN (execution command) opens a connection for data communication with the target device.
• If an error occurs, o_bErr (error completion) is turned on, and the error code is stored in o_uErrId (error code). Refer to
Page 6 Error code for details on the error codes.

Range Description
ON, OFF Specify whether to use the parameter values set by the
engineering tool or the following operation parameter
values when processing for opening a connection.
• OFF: Performs open processing according to the
target device configuration setting made by the
engineering tool. (The following operation
parameters need not be set. Any settings are ignored
if made.)
• ON: Performs open processing according to the
following operation parameters.
*1
0, 1 Select the protocol to be used for the connection to be
opened.
• 0: TCP/IP
• 1: UDP/IP
*1
0 to 2 Select the connection open method.
• 0: Active open or UDP/IP
• 1: Unpassive open
• 2: Fullpassive open
1 to 5548, 5570 Specify the port number of the own node.
to 65534 Own node port numbers 1 to 1023 are generally
reserved port numbers, and 61440 to 65534 are used
by other communication functions. Therefore, port
numbers 1024 to 5548 and 5570 to 61439 should be
used.
1 to 65534 Specify the destination port number.
0.0.0.1 to Specify the IP address of target device.
