MKS 146 Vacuum Gauge Measurement communication driver

MKS 146 Vacuum Gauge Measurement communication driver is the driver to communicate with type 146 series controller of MKS Instruments, Inc. in U.S.A.

1. Read Settings

<Figure 1> is read setting example of MKS 146 Vacuum Gauge Measurement communication driver.

<Figure 1>  Read setting example of MKS 146 Vacuum Gauge Measurement communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(2), Data Bit(7), Stop Bit(1) respectively, according to setting of controller.

Also you can set 'use of BCC check'( 0 : don't use, 1 : use, default = 0) by using option part.

Note) Baud rate(300 ~ 9600), parity bit(0, 1, 2), data bit(7, 8) of MKS TYPE 146 controller can set by front panel button.

MKS 146 Vacuum Gauge Measurement communication driver read schedule

Read schedule setting parameters are as follows:

1) Station – don't care.

2) Read command – command and channel = 601x, 602x, 603x, 604x, 605x, 606x, 6071, 608x, 6091, 60A*, 60B*, 60C1, 60D1, 60E1, 60F1, 7011, 7021, 7031, 7041, 7051, 7061.

( x : 1, 2, 3, 4, 5, 6 = channel number,  * : A, B, C, D =  Parameter, 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 – fixed to 1.

Read schedule example)

READ,     0,  6014,     0,    0,   1,

READ,     0,  6074,     0,    2,   1,

READ,     0,  7061,     0,   10,   1,

<Table 1> is read command and contents of MKS 146 Vacuum Gauge Measurement communication driver.

 MKS 146 Vacuum Gauge Measurement communication driver store the same data in WORD, DWORD, FLOAT, STRING( for related command ) memory, but the data format are different.

If you click the icon  in protocol option part at <Figure 1>, you can see the dialog box such as <Figure 2>. you can also set read schedule by using this part. 

<Figure 2> Example of MKS 146 Vacuum Gauge Measurement communication driver’s Option dialog box

You can set read schedule by using , , button and listbox of <Figure 2>.

Also, you can set use of BCC check by using the part of 'Use BCC Data Filed' shown in <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 set MKS 146 Vacuum Gauge Measurement by using 'write settings'. 

Digital Write

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             don't care.

3)  ADDRESS          don't care.

4)  Extra1                  writing command and element, refer to <Table 3>. ( don't input 1st @ character, last CR and BCC )

5) Extra2                   don't care.

<Table 3> is write command and element of MKS 146 Vacuum Gauge Measurement communication driver.

<Table 3> Write command and element of MKS 146 Vacuum Gauge Measurement communication driver

Write example 1)

PORT:0,  station:1, ADDRESS:0000, Extra1: 0812:ON,  Extra2 : 0

The setting parameter shown above is Channel Power ON of no. 2 setting example.

Write example 2)

PORT:0,  station:1, ADDRESS:0000, Extra1: 0812:OFF,  Extra2 : 0

The setting parameter shown above is Channel Power OFF of no. 2 setting example.

Analog Write 

Analog write and digital write have the same setting parameters except output value. 

3. Connection of communication cable and main power

Connection of communication cable and main power are as follows:

Connection of communication cable

Please connect direct RS-232C communication cable to 9 pin connector of MKS TYPE 146 controller.

<Figure 4> is connection example of main power and communication cable to MKS TYPE 146 controller.

Note) 9pin connector of MKS TYPE 146 controller use direct RS-232C communication cable.

<Figure 5> is appearance of MKS TYPE 146 controller.

 Connection of main power

Please connect 220V AC( or 110V ) AC main power to power input connector such as <Figure 4>.

Note) Check main power input type,  230V or  110V selection switch.

4. Setting of baud rate

MKS TYPE 146 controller can set baud rate by using setting button of front panel. ( refer to <Figure 5> )

1) Please ‘DISPLAY MODE’ button several times and enter to ‘SETUP’ mode.

2) Press 'Up', 'Down' button several times when blinking the left, up side number.

3) Press '5' button. Then will be displayed '9600' (or other character ).

4) Press ‘ENTER’ button. Then, will be blink 'the number'.

5) Please select baud rate(300, 1200, 2400, 4800, 9600) by pressing 'Up', 'Down' button.

6) Press 'ENTER' button. Then will be displayed ‘146’( or DL) character.

7) Select protocol type to '146' and press 'ENTER' button. Then will be displayed ‘7E’, ....

8) Select 'data bit' by pressing '7' or '8' button. Select 'parity bit'( EVEN/ODD/NONE ) by using 'Up', 'Down' button.

9) Complete setting by pressing ‘DISPLAY MODE’ button.
