Setting System - Mitsubishi Electric MELSEC iQ-RJ71EN71 User Manual

• When transferring messages which are sent to other stations specifying network number and station
number, to another network, "Gateway Parameter Settings" in "Application Settings" is required. ( Page
263 Gateway Parameter Settings)
• "Network/Station No. <-> IP information setting" is required when other stations are accessed via other
Ethernet network systems and must be registered in all the Ethernet-equipped module which has the
network number and station number.
• The setting can be made in the CPU module (built-in Ethernet port part) if it has the firmware version
supporting communications by network number/station number. (Page 406 Added and Enhanced

Automatic Response System
IP Address Calculation System
Table Conversion System
Combination System
• In MELSOFT connection using UDP/IP, if the external device is not registered in the conversion table of
table conversion system, the Ethernet-equipped module communicates with the device using the automatic
response system. Therefore, even when both of communications with different networks using the link
dedicated instruction and MELSOFT connection are performed simultaneously, the Ethernet-equipped
module can communicate with the external device in MELSOFT connection regardless of the registered
data in the conversion table.
• If the IP address and port number cannot be retrieved when IP address calculation system, table conversion
system, or combination system is set, the Ethernet-equipped module will retrieve them using the automatic
response system and send a response to the external device.
