4.20.7 Batch setting Mitsubishi HMI (GOT) connection parameters (Pr. 999)
The read value is always "9999."
.......Specifications differ according to the date assembled. Refer to page 316 to check the SERIAL number.
(1) Automatic parameter setting (Pr. 999)
Setting Pr. 999 = "10" will automatically set the communication parameters required to connect a GOT to the PU
connector.
To operate in the parameter setting mode, go to "AUTO" "GOT", then write "1".
The following tables show which parameters are changed in each of the automatic parameter settings.
