5.Buffer Memories (BFM)
5.1Buffer memory List
Note:
1)When writing to BFM #0 (CH1 counter mode), BFM #1 to #27 and #29 bit1 to 6 will be initialized. When writing to BFM #40 (CH2 counter mode), BFM #41to #67 and #29 bit10 to 15 will be initialized.
When setting the counter mode, use a TOP (pulsed) instruction, or M8002(initial pulse) to drive the TO instruction. (The continuous operation type cannot be used.)
2)Read/Write of 16 bit data
When using a positive value between K32,768 and K65,535 with 16 bit counters, read/writes of data, such as the current value, ring length, preset data, YH1/YH2 compare value, maximum count value and the minimum count value should use the 32-bit forms of FROM/TO instructions ((D)FROM, (D) TO).
3)Read/write of 32 bit data
The usage of a 32-bit FROM/TO instruction is recommended.
In the event that a 16-bit FROM/TO instruction is used, the following cases need to be considered.
?If the writing order is low word first and then high word, the 32 bit data will be written normally. Data becomes valid after both low and high words are written.
?In the event that data is not written in the order low word first and then high word, the error bit b7 of BFM #29 turns ON.

Ring length [BFM #3, #2 (CH1), #43, #42 (CH2)]
When setting the upper limit value of the 16 bit counters, the setting range is K2 to K65536. (Default value: K65536)
Please use the DTO instruction and write data as 32 bit data.
When ring length K100 is specified, the current value of the counter is changed as 5.2.4Command [BFM #4 (CH1), #44 (CH2)]
*1When b0 is set to ON and the DISABLE input terminal to OFF, the counter is
permitted to start counting input pulses.*2Unless b1 is set to ON, YH1 (compared output) does not turn ON.*3Unless b2 is set to ON, YH2 (compared output) does not turn ON.
*4When b3=ON, YH2 output is reset if YH1 output is set, and YH1 output is reset if
YH2 output is set. When b3=OFF, YH1 and YH2 output act independently, and do not reset each other.
The mutual reset action becomes valid only when both the YH1 comparison
output and the YH2 comparison output are permitted (b1, b2=ON).*5When b4=OFF, the preset function using the PRESET input terminal is disabled.*6When bit 5 is set to ON, the counter will be stopped and reset and the outputs
YH1 and YH2 will be switched OFF when the PLC is set from RUN to STOP .*7When bit 8 in BFM #4 is set to ON, the error flags bit 1 to 6 in BFM #29 will be
reset. The shared error flags (bit 7 and bit 8) will also be reset if no error on the other counter channel requires them to remain ON. When bit 8 in BFM #44 is set to ON, the error flags bit 10 to 15 in BFM #29 will be reset. The shared error flags (bit 7 and bit 8) will also be reset if no error on the other counter channel requires them to remain ON. After clearing BFM #29 error flags this flag will be reset automatically.*8b9 to b12 can perform a forced set of the YH1 output or the YH2 output, and

5.2.5Preset data [BFM #11, #10 (CH1), #51, #50 (CH2)]
When BFM #4, #44 b4 is ON and the PRESET input is switched from OFF to ON,preset data is stored in BFM #21, #20 (CH1) #61, #60 (CH2) (counter current value).
5.2.6
YH1 compare value [BFM #13, #12 (CH1), #53, #52 (CH2)], YH2 compare value [BFM #15, #14 (CH1), #55, #54 (CH2)]
?The comparison set value for the output currently written here and the present value of the counter are measured, and when the comparison result is equal,the YH1 output or the YH2 output is set to ON within 30 μs.
?Output occurs when the current value becomes equal to the compare value but only if b1 and b2 of BFM #4, #44 are ON. Once an output is set, it remains ON 5.2.7Counter current value [BFM #21, #20 (CH1), #61, #60 (CH2)]
The current value of the counter can be read by the PLC. It will not be an accurate 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.
5.2.8
Maximum count value [BFM #23, #22 (CH1), #63, #62 (CH2)],Minimum count value [BFM #25, # 24 (CH1), #65, #64 (CH2)]
These BFM store the maximum and minimum value reached by the counter. If the power is turned off, the stored data is cleared. Any value written to maximum and minimum count value in 16 bit counter mode which is exceeding the valid range (0 <= value < ring length) will be automatically adjusted. Values < 0 will be adjusted to 0, values >= ring length will be adjusted to "ring length" - 1.

WIRING
PRECAUTIONS
?When drilling screw holes or wiring, make sure cutting or wire debris does not enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
?Make sure to observe the following precautions in order to prevent any damage to the machinery or accidents due to abnormal data written to the PLC under the influence of noise:
1)Do not bundle the main circuit line together with or lay it close to the main circuit, high-voltage line or load line. Otherwise, noise disturbance and/or surge induction are likely to take place. As a guideline, lay the control line at least 100mm (3.94") or more away from the main circuit or high-voltage lines.2)Ground the shield wire or shield of the shielded cable at two points; on the PLC and the device on other end. However, do not use common grounding with heavy electrical systems.

5.Buffer Memories (BFM)
5.1Buffer memory List
Note:
1)When writing to BFM #0 (CH1 counter mode), BFM #1 to #27 and #29 bit1 to 6 will be initialized. When writing to BFM #40 (CH2 counter mode), BFM #41to #67 and #29 bit10 to 15 will be initialized.
When setting the counter mode, use a TOP (pulsed) instruction, or M8002(initial pulse) to drive the TO instruction. (The continuous operation type cannot be used.)
2)Read/Write of 16 bit data
When using a positive value between K32,768 and K65,535 with 16 bit counters, read/writes of data, such as the current value, ring length, preset data, YH1/YH2 compare value, maximum count value and the minimum count value should use the 32-bit forms of FROM/TO instructions ((D)FROM, (D) TO).
3)Read/write of 32 bit data
The usage of a 32-bit FROM/TO instruction is recommended.
In the event that a 16-bit FROM/TO instruction is used, the following cases need to be considered.
?If the writing order is low word first and then high word, the 32 bit data will be written normally. Data becomes valid after both low and high words are written.
?In the event that data is not written in the order low word first and then high word, the error bit b7 of BFM #29 turns ON.

1)16/32-bit counter modes a)32-bit counter modes
Modes: K0, K2, K4, K6, K8, K10
A 32-bit binary counter which executes UP/DOWN counting will change from the lower limit value to the upper limit value or the upper limit value to the lower limit value when overflow occurs. Both the upper and lower limit values are fixed values: the upper limit value is +2,147,483,647, and the lower limit value is -2,147,483,648.b)16-bit counter modes
Modes: K1, K3, K5, K7, K9, K11
A 16-bit binary counter handles only positive values from 0 to 65,535. Changes to zero from the upper limit value or to the upper limit value from zero when overflow occurs;the upper limit value is determined by BFMs #3 and #2 (CH1), #43 and #42 (CH2).3)2-phase counter [2 edge-count] (K2, K3)4)2-phase counter [4 edge-count] (K4, K5)

Ring length [BFM #3, #2 (CH1), #43, #42 (CH2)]
When setting the upper limit value of the 16 bit counters, the setting range is K2 to K65536. (Default value: K65536)
Please use the DTO instruction and write data as 32 bit data.
When ring length K100 is specified, the current value of the counter is changed as 5.2.4Command [BFM #4 (CH1), #44 (CH2)]
*1When b0 is set to ON and the DISABLE input terminal to OFF, the counter is
permitted to start counting input pulses.*2Unless b1 is set to ON, YH1 (compared output) does not turn ON.*3Unless b2 is set to ON, YH2 (compared output) does not turn ON.
*4When b3=ON, YH2 output is reset if YH1 output is set, and YH1 output is reset if
YH2 output is set. When b3=OFF, YH1 and YH2 output act independently, and do not reset each other.
The mutual reset action becomes valid only when both the YH1 comparison
output and the YH2 comparison output are permitted (b1, b2=ON).*5When b4=OFF, the preset function using the PRESET input terminal is disabled.*6When bit 5 is set to ON, the counter will be stopped and reset and the outputs
YH1 and YH2 will be switched OFF when the PLC is set from RUN to STOP .*7When bit 8 in BFM #4 is set to ON, the error flags bit 1 to 6 in BFM #29 will be
reset. The shared error flags (bit 7 and bit 8) will also be reset if no error on the other counter channel requires them to remain ON. When bit 8 in BFM #44 is set to ON, the error flags bit 10 to 15 in BFM #29 will be reset. The shared error flags (bit 7 and bit 8) will also be reset if no error on the other counter channel requires them to remain ON. After clearing BFM #29 error flags this flag will be reset automatically.*8b9 to b12 can perform a forced set of the YH1 output or the YH2 output, and
reset.
The output is not changed when the forced set and reset are performed simultaneously.

5.2.5Preset data [BFM #11, #10 (CH1), #51, #50 (CH2)]
When BFM #4, #44 b4 is ON and the PRESET input is switched from OFF to ON,preset data is stored in BFM #21, #20 (CH1) #61, #60 (CH2) (counter current value).
5.2.6
YH1 compare value [BFM #13, #12 (CH1), #53, #52 (CH2)], YH2 compare value [BFM #15, #14 (CH1), #55, #54 (CH2)]
?The comparison set value for the output currently written here and the present value of the counter are measured, and when the comparison result is equal,the YH1 output or the YH2 output is set to ON within 30 μs.
?Output occurs when the current value becomes equal to the compare value but only if b1 and b2 of BFM #4, #44 are ON. Once an output is set, it remains ON 5.2.7Counter current value [BFM #21, #20 (CH1), #61, #60 (CH2)]
The current value of the counter can be read by the PLC. It will not be an accurate 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.
5.2.8
Maximum count value [BFM #23, #22 (CH1), #63, #62 (CH2)],Minimum count value [BFM #25, # 24 (CH1), #65, #64 (CH2)]
These BFM store the maximum and minimum value reached by the counter. If the power is turned off, the stored data is cleared. Any value written to maximum and minimum count value in 16 bit counter mode which is exceeding the valid range (0 <= value < ring length) will be automatically adjusted. Values < 0 will be adjusted to 0, values >= ring length will be adjusted to "ring length" - 1.

Error status in the FX 3U -2HC can be checked by reading the contents of b0 to b15of BFM #29 to auxiliary relays of the PLC.
The error flag of b1 to b8 is reset-table with ON of BFM #4 b8. The error flag of b7,b8 and b10 to b15 is resettable with ON of BFM #44 b8. The error flags in BFM #29 can also be reset by writing 0 to it. The Hardware error flag (bit 9 of BFM #29)can not be cleared.
5.2.12Model identification code [BFM #30]
This BFM stores the identification number for the FX 3U -2HC.The identification number for the FX 3U -2HC unit is K4020.
By reading this identification number, the user may create built-in checking routines to check whether the physical position of the FX 3U -2HC matches that of the software.
6.Example Program
The ON/OFF status of M10 to M25 is written in BFM #4 (CH1) of special function block No.2 by the following program, and b0 to b15 actions. Among these, b0 to b4 are always ON as controlled by M10-M14.
Furthermore, b8 (M18), b9 (M19), and b10 (M20) are controlled by input X004 of unit. Other instructions to read the current value of the counter, status etc. can be
Bit N0.Error Status

When the upper or lower limit is exceeded on a 32-bit counter.b15Set when the counter underflows the lower limit. (CH2)
Error status in the FX 3U -2HC can be checked by reading the contents of b0 to b15 of BFM #29 to auxiliary relays of the PLC. These error flags are resettable BFM #4, #44 b8.
7.Preliminary checks
1)Check that the I/O wiring and extension cable of the FX 3U -2HC are properly connected.
2)The FX 3U -2HC occupies 8 points of I/O on the FX 3U , FX 3UC expansion bus. The 8 points can be allocated from either inputs or outputs.
5V DC 245mA power is supplied from the main or extension power supply units for the FX 3U -2HC. 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. Remember to initialize the count (BFM #4, #44 b0), preset (BFM #4,#44 b4), and output (BFM #4, #44 b2, b1) prohibits. The YH1/YH2 outputs are reset during start.Note:
Inputting pulses higher than the maximum frequency may cause miscounting in the FX 3U -2HC or a FROM/TO error in the PLC main unit.
8.Diagnostics
1)The following LEDs on the main panel of the FX 3U -2HC may help you to troubleshoot the unit.a)
A, B:
Goes on/off as A, B input turn ON/OFF. It can be checked by rotating the encoder slowly.b)UP , DOWN:
Lights up to indicate whether the counter is going up (UP) or down (DOWN).c)PRE, DIS:
The appropriate LED lights up when the PRESET (PRE) terminal or the DISABLE (DIS) terminal is ON.d)YH1, YH2:
The appropriate LED lights up when YH1/YH2 output is turned on.
2)You can check the error status by reading the content of BFM #29 to the PLC.
