(6) Precautions
(a) When an error occurs during continuous operation, if the program processes the variables, etc.,
in one step, the display will start not from the error block but instead from the head of the
variables in which there was a preread error block. Six lines of the program will be displayed.
Example) X100.;
← When the buffer correction mode is entered, these six lines will be
displayed.
X-10000000; ← Example when this block has a program error (P35).
If the macro block has seven or more lines, the block in which the program error occurred will
not be displayed.
(b) Edit lock C
When edit lock C is valid (base specification parameter #1121 edlk_c=1), buffer correction of
program numbers 9000 to 9999 is not possible. The "E16 EDIT LOCK C" error will occur.
When the base specification parameter #1122 pglk_c=1/2, buffer correction of program
numbers 9000 to 9999 is not possible. The "E16 EDIT LOCK C" error will occur.
(Note) When either base specification parameter #1121 edlk_c or #1122 pglk_c is set, the
power must be rebooted.
(c) Data protection key
Buffer correction is possible when data protection key 1 (*KEY1: Y238) is ON.
Buffer correction is possible when data protection key 2 (*KEY2: Y239) is ON.
Buffer correction is not possible when data protection key 3 (*KEY3: Y23A) is ON. The message
"DATA PROTECT" will appear.
(d) Edit lock B
When edit lock B is valid (control parameter #8105 EDIT LOCK B = 1), buffer correction of
program numbers 8000 to 9999 is not possible. The "E15 EDIT LOCK B" error will occur.
