If you download a program with no MEWNET-W2 data to the same PLC to which you downloaded a program with MEWNET-W2 data, the setting data will be deleted.
Please note the following when using MEWNET-W2:
MEWNET-W2 supports PLC Link when you use a Multi-Wire Link Unit for MEWNET-W2.
You can use the MEWNET-W2 PLC Link function by downloading this data to PLC.
The following Multi-Wire Link Unit versions are available for this software:
Ver.1.60 or higher
The following CPU versions are available for this software.
FP2: Ver.1.20 or higher
FP2SH: Ver.1.10 or higher
If you are using an older PLC version, you must make your settings using a PLC (ladder) program. Please refer to the Multi-Wire Unit manual for details.
With the FP2, system register no. 2 should be set to 2 or higher.
The MEWNET-W2 data is retained even when you change the PLC mode from PROG to RUN or turn off the power while the PLC is in RUN mode.
