4.
Select comparison output number or label number for each enabled comparison.
Comparison Output
When comparison output is selected for the comparison action, specify an output number available on the CPU module
in the
Comparison Output
field. When the preset value is reached (single-phase and two-phase high-speed counters) or
current value overflow or underflow occurs (two-phase high-speed counter), the specified comparison output is turned
on and remains on until a comparison output reset special internal relay (M8030, M8034, M8040, or M8044) is turned
on.
Label Number
When interrupt program is selected for the comparison action, specify a label number to jump to. When the preset value
is reached (single-phase and two-phase high-speed counters) or current value overflow or underflow occurs (two-phase
high-speed counter), program execution jumps to the specified label number in the subroutine program.
5.
Select to keep current value or not.
For the HSC1 and HSC4, the current value can be kept when reaching preset value 1 and preset value 2 to enable another
comparison. To keep the current value, check the box. When this box is not checked, the current value in D8210/D8211
or D8226/D8227 is reset to the reset value to start another counting cycle.
6.
Select to use the HSC reset input or not.
Click the check box to enable high-speed counter reset input I2 for HSC1 or I5 for HSC4 only. When input I2 or I5 is turned
on, the current value is reset to the reset value to start another counting cycle.
HSC1
The current value is reset to the value stored in D8216/D8217 (high-speed counter reset value).
High-speed counter HSC1 counts subsequent input pulses starting at the reset value.
HSC4
The current value is reset to the value stored in D8232/D8233 (high-speed counter reset value).
High-speed counter HSC4 counts subsequent input pulses starting at the reset value.
Since these settings relate to the user program, the user program must be downloaded to the MicroSmart after changing
any of these settings.
