10.5.4 Entry code
• Register and delete the entry code.
- When registering the entry code, place the cursor on the
[ENTER] key, input the entry code, then press the [GO] key.
- When not changing the registered entry code, press the
[GO] key. (In the default status, no entry code is registered.)
- When deleting the already registered entry code, place the
cursor on the [DELETE] key, input the entry code, then press
the [GO] key.
Handling of the entry code
• By registering the entry code, changes in programs and data can be prohibited, and
programs can be protected.
• There are three protective levels, "the all operation prohibition level (A)", "Read/Incorrect
write protection level (B)" and "the erroneous write prohibition level (C)".
• When the HPP is started up in the online mode for a program in the PLC in which the entry
code has been registered, the program requests the operator to input the entry code first. If
the entry code input by the operator agrees with the already registered entry code, all
operations are enabled in the HPP.
• If the entry code is unknown, it is impossible to delete only the entry code.
If it is all right to erase the entire program (including all parameters and the entry code),
input the special entry code (by pressing the [S’P] key eight times) to erase the entire
program, then proceed to operate the HPP.
