The Ethernet and serial communication settings for the MEWTOCOL OPC Server compatibility namespace are stored by the corresponding MEWNET manager.
Because from this version the PxMEWNET manager is used instead of the NAiS MEWNET manager you have to execute the following steps to keep the communication settings:
Close the FP OPC Server
Copy the files “NAIS_MewMultiEther.dat” and “NAIS_MEWCOMM.INI” from folderC:\Users\UserName\AppData\Roaming\Panasonic MEW Control\MEWNET Manager into folder C:\Users\UserName\AppData\Roaming\Panasonic-ID SUNX Control\PxMEWNET
Replace <UserName> in the folder name with your Windows login name.
Rename “NAIS_MewMultiEther.dat” to “PxMewMultiEther.dat”
Rename “NAIS_MEWCOMM.INI” to “PxMEWCOMM.INI”
