Chapter 15 Password Management and Data Protection
If users want to monitor the devices in a DVP series PLC through DVPDU-01, they can select the
TS-01 mode in DVPDU-01. If users want to read data from a DVP series PLC through DVPDU-01,
or write data into a DVP series PLC through DVPDU-01, they can select the TC-01 mode in
DVPDU-01. If users want to read data from a DVP series PLC in which a PLC password is set
through DVPDU-01, or write data into a DVP series PLC in which a PLC password is set through
DVPDU-01, they can set a TC-01 password key which is the same as the PLC password in
DVPDU-01. After the system makes sure that the TC-01 password key set in DVPDU-01 is the
same as the PLC password, the data will be read from the DVP series PLC, or the data will be
written into the DVP series PLC. Besides, when users read data from a DVP series PLC in which no
PLC password is set through DVPDU-01, or write data into a DVP series PLC in which no PLC
password is set through DVPDU-01, the system sets a PLC password in the DVP series PLC. The
PLC password set in the DVP series PLC is the same as the TC-01 password key set in DVPDU-01.
The setting of a TC-01 password key and the unlocking of a TC-01 password key are described
below. Users have to make sure that DVPDU-01 is on standby before they set a TC-01 password. If
an error occurs in DVPDU-01, or DVPDU-01 is in a process, the users have to eliminate the error, or
complete the process. Please refer to DVPDU-01 User Manual for more information.
(1) After the users press ESC on DVPDU-01 for three seconds, the password setting screen will
appear.
