Built-in Inputs Section 6-1
Procedure
Select high-speed counter 1 and/or 2.
Select the pulse input method, reset
method, and counting range.
Select the kind of interrupt (if any).
Wire inputs.
PLC Setup settings
Ladder program
• Pulse input methods: Differential phase (4x), Pulse +
direction, Up/Down, or Increment
• Reset methods: Phase-Z + Software reset or Software
reset
• Counting ranges: Linear mode or Ring mode
• No interrupt
• Target value comparison interrupt
• Range comparison interrupt
• For high-speed counter 0, connect IN3, IN8, and
IN9. For high-speed counter 1, connect IN2, IN6,
and IN7.
• Enable high-speed counter 0 and/or 1.
High-speed Counter 0 (1) Enable/Disable:
Bits 12 to 15 of Programming Console address 50 (53).
1 Hex: Enable the high-speed counter (60 kHz.)
2 Hex: Enable the high-speed counter (100 kHz.)
Set the pulse input method(s).
• High-speed Counter 0 (1) Pulse Input Mode:
Bits 00 to 03 of Programming Console address 50 (53).
0 Hex: Differential phase (4x)
1 Hex: Pulse + direction
2 Hex: Up/Down
3 Hex: Increment
Set the reset method(s).
• High-speed Counter 0 (1) Reset Method:
Bits 04 to 07 of Programming Console address 50 (53).
0 Hex: Phase-Z + Software reset
1 Hex: Software reset
Set the counting range(s).
• High-speed Counter 0 (1) Counting Mode:
Bits 04 to 07 of Programming Console address 50 (53).
0 Hex: Linear mode
1 Hex: Ring mode
• Program the interrupt task (with any interrupt number between 0
and 255) to be executed when using a target value comparison
or range comparison interrupts.
• When performing target value comparisons, execute the
CTBL(882) instruction with C=0000 Hex to register a target
value comparison table and start the comparison.
• When performing range value comparisons, execute the
CTBL(882) instruction with C=0001 Hex to register a range
comparison table and start the comparison.
• To register a target value comparison table without starting the
comparison, execute the CTBL(882) instruction with C=0002
Hex.
• To register a range comparison table without starting the
comparison, execute the CTBL(882) instruction with C=0003
Hex.
• The INI(880) instruction can be used to change the PV.
• The INI(880) instruction can be used to start comparison with
the registered target value comparison table or range
comparison table.
• The PRV(881) instruction can be used to read the high-speed
counter PVs, read the status of the high-speed counter
comparison operation, or read the range-comparison results.
• The High-speed Counter Gate Bit (A53108 and A53109) can be
turned ON to stop counting pulses input to high speed counter 0
and 1.
