Ip Address Of The Built-In Ethernet Port - Mitsubishi Electric Q03UDVCPU User Manual

11.1

IP Address of the Built-in Ethernet Port

For IP address of the built-in Ethernet port, a value of the built-in Ethernet port setting of the PLC Parameter is set at
the initial processing of the CPU module. When this function is used, the value stored in the IP address storage area
(flash ROM) will be set to the IP address of the built-in Ethernet port which is set during the initial processing of the
CPU module, instead of the value set in the parameter.
(1) Write and clear operation to the IP address storage area (flash ROM)
Write a value of IP address to the IP address storage area (flash ROM). The special relay and special register are
used to perform the write and clear operations.
(2) Execution timing of writing to and clearing the IP address storage area (flash
ROM)
Write and clear processing are executed in the END processing. Therefore, the scan time is increased during
execution.
