is enabled.

2. When b1 is set to 1, YH0 (hardware comparison

output) output is enabled.

3. When b2 is set to 1, YH1 (hardware comparison

output) output is enabled.

4. When b3 is set to 1, YH0 and YH1 affect each

other (they cannot be ON/OFF simultaneously). In
other words, when YH0=ON, YH1 must be OFF
and when YH0=OFF, YH1 must be ON. When
b3=0, YH0 and YH1 activate independently.

5. When b4=0, terminal “PRE” is disabled.
6. When b8=1, all error flags (CR#29) will be cleared.
7. When b9=1, YH0 output will be cleared to be OFF.
8. When b10=1, YH1 output will be cleared to be

OFF.

9. When b11=1, YH0 output will be ON.
10.When b12=1, YH1 output will be ON.

Setting notes:

After setting CR#4, b8~b12 will be cleared to 0.

It needs to set to disable count(b0=0) before setting count mode (CR#5).

TRIAL RUN & TROUBLESHOOTING

MPU connects to HC extension module

1. Make sure that the power of MPU and extension unit is OFF before wiring.

2. Open extension port of EH MPU and connect to HC extension unit with cable. There is no

connection order for EH MPU to connect extension unit, mix connection is allowed.

3. The power supply of HC extension unit must be external +24VDC power supply.

4. Before power up, check if the load circuit of output points YH0 and YH1 is correct, especially

the circuit between YH0+, YH0- and YH1+, YH1-. There is a Zener Diode that is connected
between YH0+, YH0- and YH1+, YH1- in HC. If the positive/negative pole is wrong, it may
cause unexpected result.

5. Before power up, check if A phase or B phase connects to correct voltage level. (there are

three voltage level: +24, +12V and +5V) If +24V signal connects to +5V input terminal, it may
damage internal circuit.

6. After power up MPU, it will start to detect extension module. If no external +24VDC power is

applied to HC at this time or power is applied after EH MPU completing detecting extension
module, the connection will fail. Therefore, power wiring and power supply timing should be
as following.

Timing analysis

When power supply for HC is +24V_INT:

t5＞t3, power is ON and the connection of HC
extension unit is normal.

When power supply for HC is +24V_EXT:

Because start time (t2) of external power supply
for HC extension module is unknown, user must
make sure that t2+t4 ＜ t1+t5, otherwise HC
extension module cannot be detected by MPU.

7. The maximum special extension modules number for EH MPU connects is 8 special

extension modules. After power is ON, EH will save module codes of connected special
modules in D1320~D1327 in order. The module code of 01HC is H’0120. It indicates
communication is OK when H’0120 is displayed in the corresponding special D register by
using HPP02 or other monitor software.

Troubleshooting

Judge the errors by the indicators on the front panel. When errors occurred on DVP PLC,
please check:

☼ “POWER” LED

The “POWER” LED at the front of HC extension module will be lit (in green) if the power
is on. If the indicator is not on when power up, please remove the wiring on terminals
+24V. Once the indicator lights after this, it means that the 24V DC power supply of the
PLC is overloaded. Please do not use the DC power supply from the +24V terminals,
but use a DC24V power supply instead.

☼ L.V. LED

The “L.V.” LED at the front of HC extension module will be lit if input voltage is not
enough. The extension module won’t active at this time.
