1. INTRODUCTION

The hardware high-speed counter block is a 2-phase 50 kHz high-speed counter. It is a special function block for the FX2N, FX

2NC

, FX3U, FX

3UC

series PLC.

• FROM/TO instruction transfers the PLC data (i.e. parameters, comparing value and present value).

• The FX2N-1HC occupies 8 points of I/O on the FX2N, FX

2NC

, FX3U, FX

3UC

expansion bus. The 8 points

can be allocated from either inputs or outputs.

• Differential-Line-Driver (AM26C31 or equivalent) and open collector output encoders are available for FX2N-1HC.

• The source of your input signal should be a 1 or 2 phase encoder. A 5V, 12V, or 24V power source can be used. An initial value setting command input (PRESET) and a count prohibit command input (DISABLE) are also available.

• The FX

-1HC has two outputs. When the counter value coincides with an output compare value, the appropriate output is set ON. The output transistors are individually isolated to allow either sink or source connection methods.

• Various counter modes, such as 1-phase or 2-phase, 16-bit or 32-bit modes, can be selected using commands from the PLC. Allow the FX

-1HC unit to run only after setting these mode parameters.

2) BFM #3, #2 Ring length

Note: Write counter data with (D) TO

• Count data is always handled as a pair from two 16-bit values in this special function block. 16-bit 2’s complement value stored in the registers of the PLC cannot be used.

• When you are writing a positive value between K32,768 and K65,535, the data should be treated as a 32-bit value even when a 16-bit ring counter is used.

• When transferring counter data to/from this special function block, always use the 32-bit forms of the FROM/TO instructions ((D) FROM, (D) TO).

3) BFM #4 Command

4) BFM #11, #10 Preset data

• Data to used as the initial value when the counter starts to count.

• Data becomes valid when b4 of BFM #4 is set to ON, and PRESET input terminal changes from OFF to ON. The default value of the counter is zero. You can change it by writing a value into BFM #11 and #10 or by using the command below.

• The initial counter value can also be set by writing the data directly into BFM #21 and #20 (current value of the counter).

5) BFM #13, #12 Comparison value for YH output, BFM #15, #14 Comparison value for YS output

• After comparing the current value of the counter with the value written in BFM #13 and #12, BFM #15 and #14, the hardware and software comparator in the FX

-1HC outputs the comparison

result.

• YH, YS output will not turn ON if you use PRESET or the TO instruction to set the counter value equal to the comparison value. It will turn ON only when a match occurs by the counting of input pulses.

• The YS comparison operation takes about 300μs, and if a match occurs, the output goes ON.

• Output occurs when the current value becomes equal to the compare value but only if b1 and b2 of BFM #4 are ON. Once an output is set, it remains ON until it is reset by b9 or b10 of BFM #4. If b3 of BFM #4 is ON, however, one of the outputs is reset when the other is set.

6) Counter current value (BFM #21, 20)

The current value of the counter can be read by the PLC. It will not be the correct value during high-speed operations because of the communication delay. The current value of the counter can be forcibly changed by writing a 32-bit value into the appropriate BFMs from the PLC.

7) Maximum count value (BFM #23, 22)

These store the maximum and minimum value reached by the counter. If the power is turned off, the stored data is cleared.

8) Comparison status (BFM #26)

BFM #26 is for reading only. Write commands from the programmable controller are ignored.

In the above example, K100 is written into BFMs #3 and #2 of special block No.2 as a 32-bit binary value (BFM #3 = 0, BFM #2 = 100). Permitted values: K2 to K65,536.

When ring length K100 is specified, the value of the counter changes as shown above.

Stores the data that specifies the length of the 16-bit counter (default: K65,536).

1. When b0 is set to ON and the DISABLE input terminal to OFF, the counter is permitted to start counting input pulses.

2. Unless b1 is set to ON, YH (hardware compared output) does not turn ON.

3. Unless b2 is set to ON, YS (software compared output) does not turn ON.

4. When b3=ON, YS output is reset if YH output is set, and YH output is reset if YS output is set. When b3=OFF, YH and YS output act independently, and do not reset each other.

5. When b4=OFF, preset function by the PRESET input terminal is disabled.

6. When b8 is set to ON, all error flags are reset.

7. When b9 is set to ON, YH output is reset.

8. When b10 is set to ON, YS output is reset.

9. When b11 is set to ON, YH output is set ON.

Model identification code number BFM #30

This BFM stores the identification number for FX

-1HC.

The identification number for the FX

-1HC unit is K4010. By reading this identification number, the user may create built-in checking routines to check whether the physical position of the FX

-1HC matches to that of the software.

4. EXAMPLE PROGRAM

Please use the following program as a guide whenever you use the FX read the current value of the counter, status etc. can be added as required.

5. DIAGNOSTICS

5.1 Preliminary checks

1) Check that the I/O wiring and extension cable of the FX2N-1HC are properly connected.

2) 5V 90mA power is supplied from the main or extension units for the FX power overload from this and other extension blocks.

3) The counter works correctly only when data such as the counter mode (set with a pulse command), the TO command, the compare value, etc. are appropriately specified. Remember to initialize the count (BFM #4 b0), preset (BFM #4 b4), and output (BFM #4 b2, b1) prohibits. Reset the YH/YS outputs before you start.

5.2 Error checking

The following LEDs on the main panel of the FX2N-1HC may help you to troubleshoot the unit.

• φA, φB :Goes on/off as φA, φB input turn ON/OFF. It can be checked by rotating the encoder

slowly.

• UP, DN :Lights up to indicate whether the counter is going up (UP) or down (DN).

• PRESET and DIS:The appropriate LED lights up when the PRESET terminal or the DISABLE terminal

is ON.

• YH, YS :The appropriate LED lights up when YH/YS output is turned on.

You can check the error status by reading the content of BFM #29 to the PLC. Error contents are shown in section 3.3 (10).

Note that inputting the pulse higher than the maximum frequency may cause mis-counting to 1HC or a FROM/TO error to the PLC main unit.

BFM#29 Error status

b0 Set when any of b1 to b7 is ON.

b1 Set when the value of the ring length is written incorrectly (other than K2 to K65,536).

b2 Set when the preset value is written incorrectly.

b3 Set when the compare value is written incorrectly.

b4 Set when the current value is written in correctly.

b5 Set when the counter overflows the upper limit.

b6 Set when the counter overflows the lower limit.

b7 Set when the FROM/TO command is used incorrectly.

b8 Set when the counter mode (BFM#0) is written incorrectly. When outside of K0 to K11

b9 Set when the BFM number is written incorrectly. When outside of K0 to K31

auxiliary relays of the PLC.

There error flags can be reset by b8 of BFM #4.

11)

Model identification code number BFM #30

This BFM stores the identification number for FX

-1HC.

The identification number for the FX

-1HC unit is K4010. By reading this identification number, the user may create built-in checking routines to check whether the physical position of the FX

-1HC matches to that of the software.

4. EXAMPLE PROGRAM

Please use the following program as a guide whenever you use the FX2N-1HC unit. Other instructions to read the current value of the counter, status etc. can be added as required.

5. DIAGNOSTICS

5.1 Preliminary checks

1) Check that the I/O wiring and extension cable of the FX2N-1HC are properly connected.

2) 5V 90mA power is supplied from the main or extension units for the FX

-1HC. Check that there is no

power overload from this and other extension blocks.

5.2 Error checking

The following LEDs on the main panel of the FX2N-1HC may help you to troubleshoot the unit.

• φA, φB :Goes on/off as φA, φB input turn ON/OFF. It can be checked by rotating the encoder

slowly.

• UP, DN : Lights up to indicate whether the counter is going up (UP) or down (DN).

• PRESET and DIS:The appropriate LED lights up when the PRESET terminal or the DISABLE terminal

is ON.

• YH, YS :The appropriate LED lights up when YH/YS output is turned on.

You can check the error status by reading the content of BFM #29 to the PLC. Error contents are shown in section 3.3 (10).

Note that inputting the pulse higher than the maximum frequency may cause mis-counting to 1HC or a FROM/TO error to the PLC main unit.

2) BFM #3, #2 Ring length

Note: Write counter data with (D) TO

• Count data is always handled as a pair from two 16-bit values in this special function block. 16-bit 2’s complement value stored in the registers of the PLC cannot be used.

• When you are writing a positive value between K32,768 and K65,535, the data should be treated as a 32-bit value even when a 16-bit ring counter is used.

• When transferring counter data to/from this special function block, alway s use the 32-bit forms of the FROM/TO instructions ((D) FROM, (D) TO).

3) BFM #4 Command

4) BFM #11, #10 Preset data

• Data to used as the initial value when the counter starts to count.

• The initial counter value can also be set by writing the data directly into BFM #21 and #20 (current value of the counter).

5) BFM #13, #12 Comparison value for YH output, BFM #15, #14 Comparison value for YS output

• After comparing the current value of the counter with the value written in BFM #13 and #12, BFM #15 and #14, the hardware and software comparator in the FX

-1HC outputs the comparison

result.

• The YS comparison operation takes about 300μs, and if a match occurs, the output goes ON.

6) Counter current value (BFM #21, 20)

7) Maximum count value (BFM #23, 22)

These store the maximum and minimum value reached by the counter. If the power is turned off, the stored data is cleared.

This BFM stores the identification number for FX

-1HC.

The identification number for the FX

-1HC unit is K4010. By reading this identification number, the user may create built-in checking routines to check whether the physical position of the FX

-1HC matches to that of the software.

4. EXAMPLE PROGRAM

Please use the following program as a guide whenever you use the FX2N-1HC unit. Other instructions to read the current value of the counter, status etc. can be added as required.

5. DIAGNOSTICS

5.1 Preliminary checks

1) Check that the I/O wiring and extension cable of the FX2N-1HC are properly connected.

2) 5V 90mA power is supplied from the main or extension units for the FX

-1HC. Check that there is no

power overload from this and other extension blocks.

3) The counter works correctly only when data such as the counter mode (set with a pulse command), the TO command, the compare value, etc. are appropriately specified. Remem ber to initialize the count (BFM #4 b0), preset (BFM #4 b4), and output (BFM #4 b2, b1) prohibits. Reset the YH/YS outputs before you start.

5.2 E rror checking

The following LEDs on the main panel of the FX2N-1HC may help you to troubleshoot the unit.

• φA, φB :Goes on/off as φA, φB input turn ON/OFF. It can be checked by rotating the encoder

slowly.

• UP, DN :Lights up to indicate whether the counter is going up (UP) or down (DN).

• PRESET and DIS:The appropriate LED lights up when the PRESET terminal or the DISABLE terminal

is ON.

• YH, YS :The appropriate LED lights up when YH/YS output is turned on.

You can check the error status by reading the content of BFM #29 to the PLC. Error contents are shown in section 3.3 (10).

Note that inputting the pulse higher than the maximum frequency may cause mis-counting to 1HC or a FROM/TO error to the PLC main unit.

BFM#29 Error status

b0 Set when any of b1 to b7 is ON.

b1 Set when the value of the ring length is written incorrectly (other than K2 to K65,536).

b2 Set when the preset value is written incorrectly.

When value ≥ ring length in 16-bit counter mode.

b3 Set when the compare value is written incorrectly.

b4 Set when the current value is written in correctly.

b5 Set when the counter overflows the upper limit.

When the upper or lower limit is exceeded on a 32-bit counter.

b6 Set when the counter overflows the lower limit.

b7 Set when the FROM/TO command is used incorrectly.

b8 Set when the counter mode (BFM#0) is written incorrectly. When outside of K0 to K11

b9 Set when the BFM number is written incorrectly. When outside of K0 to K31
