SHN-2800 Totalizer communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – Input equipment address between 0 ~ 99.
2) Read Command – ALARM1, ALARM2, A_STATUS, PV, TOTAL, C_TOTAL, AO, SCALE_H, SCALE_L, ADJ, AL1, AL2, DEADBAND, HIGH_O, LOW_O, FACTOR (Refer to <Table 1>)
3) Read Start Address – Don’t care.
4) Save Start Address for Communication Server – Input Memory Start Address which will store the data from equipment.
5) Read Size – Read Size is fixed with 1.

<Table 1> Read commands and stored values of SHN-2800 Totalizer Communication Driver
SHN-2800 Totalizer store the same data in WORD, DWORD, FLOAT memory, but the data format are different.
If
you click the icon 
in protocol option
part, you can see the dialogue box such as <Figure 2>. you can also set
read schedule by using this part.
<Figure 2> Example SHN-2800 Totalizer Communication Driver’s Option dialogue box
You
can set read schedule by using 
, 
, 
button and listbox
of <Figure 2>.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
2. Write settings
You can change the setting values of SHN-2800 Totalizer Equipment by using write commands.
Bit write
Bit write and word write have the same setting parameters except output value(0 or 1).
Word write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Equipment ID between 0 ~ 99.
3) ADDRESS Don’t care.
4) Extra1 60 ALARM1, ALARM2, TOTAL, C_TOTAL, SCALE_H, SCALE_L, ADJ, AL1, AL2, DEADBAND, HIGH_O, LOW_O, FACTOR, POINT, T_POINT (Refer to <Table 2>)
5) Extra2 The number of decimal places. 0 = No decimal places, 1 ~ 7 = 1 ~ 7 decimal places.
<Table 2> is a description of write commands and the range of write value of SHN-2800 Totalizer communication driver.
| Command | Contents |
|
| ALARM1 | ALARM 1 Value Setting |
(Including decimal places) |
| ALARM2 | ALARM 1 Value Setting | |
| TOTAL | Integrated-Value Reset | |
| C_TOTAL | Instantaneous-Integrated-Value Reset | |
| SCALE_H | Scale High Value Setting | |
| SCALE_L | Scale Low Value Setting | |
| ADJ | Sensor Adj Value Setting | |
| AL1 |
|
0 = High Alarm, 1 = Low Alarm |
| AL2 |
|
|
| DEADBAND | AL DeadBand Value Setting |
(Including decimal places) |
| HIGH_O | High Output Value Setting | |
| LOW_O | Low Output Value Setting | |
| FACTOR | Factor Value Setting | |
| POINT | Decimal Places Setting related Instantaneous-Value | 0 = No decimal places, 1 ~ 7 = 1 ~ 7 decimal places |
| FACTOR | Decimal Places Setting related Integratead-Value |
<Table 2> Write commands and the range of write value of SHN-2800 Totalizer Communication Driver
Write example 1)
PORT : 0 STATION : 1 ADDRESS : 0000 EXTRA1 : TOTAL EXTRA2 : 0
The setting parameter shown above is an example of word write for reseting integrated-value of SHN-2800 Totalizer Equipment connected with 0 port, set to 1 station.
Write example 2)
PORT : 0 STATION : 1 ADDRESS : 0000 EXTRA1 : SCALE_H EXTRA2 : 1
The setting parameter shown above is an example of word write for changing Scale High Value of SHN-2800 Totalizer Equipment connected with 0 port, set to 1 station.
Because of ‘Extra2 = 1’, Scale High Value has one decimal place. Therefore, ‘Actual Output Value = Setting Value x 10’.
Block-Write
SHN-2800 Totalizer communication driver don’t support ‘Block write’.
3. Communication Cable Connection of EnerPulse Power Supply Equipment
You can connect SHN-2800 Totalizer Equipment and communication cable in the following ways.
Communication Cable Connection
