SPECIFYING AND DISPLAYING SYSTEM PARAMETERS
(SYSPRM)
Display the system parameter screen by pressing soft key [SYSPRM] on
the basic programmer menu. Move the cursor to necessary system
parameters and specify them according to the menu displayed on the
screen. When this function is selected, if the sequence program is in
operation, the PMC management software automatically stops this
function.
Specifies whether the counter value is used in binary or BCD by
functional instruction CTR.
CAUTION
After changing a counter data type, set up the counter value
again.
Specifies the increment or decrement of processing time of the 1st and 2nd
level parts of the ladder program in the range of 1% to 150%. This
increases or decreases the scanning time of the ladder program. This
parameter influences the processing time of the 3rd level part of the ladder
program and the language program.
If 100% is specified, the time of 5 ms for an 8 ms cycle is used to process
the 1st and 2nd level parts of the ladder program. The remaining 3 ms is
used to process the 3rd level part of the ladder program, language
program, and PMC screen display.
If 120% is specified, the time of 6 ms is used to process the 1st and 2nd
level parts of the ladder program. This reduces the scanning time of the
ladder program, thus enabling the ladder program to be executed at high
speed. Note that the processing time required for the 3rd level part of the
ladder program, language program, and PMC screen display is
substantially reduced. If the undivided system is specified too, this
parameter is validated.
If a value less than 40% is specified, 40% is assumed. If a value greater than
120% is specified, 120% is assumed.
The processing time of the 1st and 2nd parts of the ladder program is
obtained by the following formula:
Processing time of the 1st and
2nd parts of the ladder program=
5msec

The processing time of the 3rd level part of the ladder program, language
program, and PMC screen display
= 8 ms – (processing time of the 1st and 2nd level parts of the ladder
