KVC450 Compact SHIM Gauge communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – 0 ~ 15, ID No.
2) Read Command – Command = VIR, SP1, SP2, UN.(Refer to <Table 1>)
3) Read Start Address – Don't care.
4) Save Start Address for Communication Server – saving start address of Communication Server.
5) Read Size – Read Size is fixed with 1.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> will be shown.
You can setting SP1, SP2 or Unit values of KVC450 Compact SHIM Gauge by using write commands.
Digital write
Digital write and analog write have the same setting parameters except output value(0 or 1).
Analog write
Analog write setting parameters are as follows:
1) PORT : Port no. (0 ~ 255)
2) STATION : 0 ~ 15, ID No.
3) ADDRESS : Don't care.
4) EXTRA 1 : Write Command = SP1, SP2, TORR, PA. (Refer to <Table 3>)
5) EXTRA 2 : Don't care.
<Table 2> is a description of write commands and contents of KVC450 Compact SHIM Gauge communication driver.
| Write Command | Contents | Output Value | |
| SP1 | Setting of SP1 Value | Float/Double Value | |
| SP2 | Setting of SP2 Value | Float/Double Value | |
| TORR | Unit Change to Torr | Don't care | |
| PA | Unit Change to Pascal | Don't care | |
| <Table 2> Write commands for KVC450 Compact SHIM Gauge communication driver | |||
Write example 1)
PORT:0, station:0, ADDRESS:0000, Extra1:SP1, Extra : 0
The setting parameter shown above is an example of word write for SP1 Setting of KVC450 Compact SHIM Gauge connected with 0 port.
Write example 2)
PORT:0, station:0, ADDRESS:0000, Extra1:TORR, Extra : 0
The setting parameter shown above is an example of word write for unit change to 'Torr' of KVC450 Compact SHIM Gauge connected with 0 port.
Block write
KVC450 Compact SHIM Gauge communication driver doesn’t support ‘Block write’.
