16 ETHERNET INSTRUCTIONS
16.4 Reinitializing the Module
*1 The instruction clears and reinitializes the address information of the external device held by the Ethernet module so that data
communication can be restarted. (The initialization normal completion signal (X19) turns on.)
*2 When auto negotiation is specified, use 1000BASE-T.
Processing details
• These instructions reinitializes the Ethernet module specified by (U). If changing the IP address is specified, change the IP
address of the Ethernet module of the own station.
• The execution status and the completion status of the UINI instruction can be checked with the completion device (d) and
the completion status indication device (d)+1.
• The following figure shows the operation at completion of the UINI instruction.
• The UINI instruction is executed on the rising edge (OFF to ON) of the reinitialize command.
Precautions
• When executed, the instruction forcibly closes all connections and initialize the internal information of the module.
• If the IP address is changed, communication is stopped. When an engineering tool is connected via Ethernet, the IP
address of the Ethernet-equipped module should be corrected to the new IP address in the "Specify Connection
Destination Connection" window before restarting communications.
• If the IP address is changed while "Use IP address" is selected in "Network No. and station number setting method" of the
engineering tool, the network number and station number are not changed and the value using the IP address that is set by
a parameter remains unchanged.

• Completion device (d)
This device turns on during END processing of the scan where the UINI instruction completes, and turns off during the next END processing.
• Completion status indication device (d)+1
This device turns on or off depending on the completion status of the UINI instruction.
When completed successfully: The device remains off.
When completed with an error: The device turns on during END processing of the scan where the UINI instruction completes, and turns off during the next END
processing.
