Regarding the cause of communication error with GX Works3

The communication between GX Works3 and MELSEC iQ-F Series via Ethernet connection could not be enabled. What is the possible cause?
Category : 

Answer

From the Microsoft? Windows?7's Internet Protocol Version 4 Properties, uncheck "Obtain an IP address automatically" option
and set an arbitrary IP adress that does not duplicate with the address of MELSEC iQ-F.
Also, if the subnet mask is 255.255.255.0, the first three values (first - third octets) must match the iQ-F's IP address.
*:The IP address of MELSEC iQ-F is 192.168.3.250 and 255.255.255.0 for subnet mask。
As well, the security softwares (antivirus software) may be blocking the Ethernet communication.
Check if communication is enabled by temporarily disabling the security software or by authorizing communication through the security software settings.
