Protecting Setting Data (Data lock function)
To protect setting data in the instrument, the setting data can be locked so that no changes can be made
(Data lock function). Parameters that can be locked are described below.
• Parameters of Parameter setting mode
• Parameters of Function block 01 (F01) to Function block 10 (F10) of Engineering mode
• Parameters of Function block 21 (F21) to Function block 91 (F91) of Engineering mode
(Note that parameters of Function block 91 (F91) are for monitoring only)
îš„ Set lock level
• Parameter setting mode:
Parameters can be locked by a block of parameters, using a set lock level. A parameter in
Parameter setting mode also belongs to a Function block of Engineering mode between Function
block 01 (F01) and 10 (F10). By locking a block to which the parameter belongs, the parameter
can be locked and all parameters in the same block and parameters in all blocks included in the
same lock level are locked at the same time (P. 6-25).
• Function block 01 (F01) to Function block 10 (F10):
The data can be locked function block by Function block.
• Function block 21 (F21) to Function block 91 (F91):
The data of F21 to F91 can be locked altogether at the same time. The data cannot be locked for
each Function block. When the data of F21 to F91 is locked, the screens of F21 to F91 are not
displayed.
