INFICON UL200 communication driver is the driver to communicate with leak detector controller of INFICON GmbH in Germany.

 

1. Read Settings

 

<Figure 1> is read setting example of INFICON UL200 communication driver.

<Figure 1>  Read setting example of INFICON UL200 communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to the controller.

Also you can set 'saving start address of readed string' (0 ~ 9999, default = 0 ), 'received string saving count'(default = 200), 'Timeout when multi line reading' by using option part.

 

INFICON UL200 communication driver read schedule

Read schedule setting parameters are as follows:

1) Station – Don't care(fixed to 0).

2) Read command – Command = S1 ~ S4,  S10 ~ S68,  G1 ~ G20,  Q0 ~ Q60, ... ( refer to <Table 1>, <Table 2> )

3) Read Start Address – Don't care(fixed to 0).

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – Fixed to 1.

<Table 2> Command and contents of Read, Setting command

Please refer to 'Interface Descriptions' or other manual of INFICON UL200 for more command information.

INET Lightrol communication driver store the same data in WORD, DWORD, FLOAT, STRING memory(except a part of read command), 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 the save position and count by using this part.

2. Writing settings

You can send command by using 'writing settings'. 

 

Digital Write 

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Don't care(fixed to 0).

3)  ADDRESS          Data saving start address for read command. (decimal unit)

4)  Extra1                   Command = S1 ~ S4,  S10 ~ S68,  G1 ~ G20,  Q0 ~ Q60, ... ( refer to <Table 1>, <Table 2> )

5)  Extra2                   Data saving method for read command.

1 – save only STRING memory,

2 – save WORD, DWORD, FLOAT memory,

0, 3, ... -  save STRING memory + WORD, DWORD, FLOAT memory.

 

Write example 1)

PORT:0,  station:0, ADDRESS:0400, Extra1: START,  Extra2 : 0

The setting parameter shown above is start measuring command example.

 

Write example 2)

PORT:0,  station:0, ADDRESS:0401, Extra1: CLEAR,  Extra2 : 0

The setting parameter shown above is calibration stop or delete error status command example.

 

Write example 3)

PORT:0,  station:0, ADDRESS:0402, Extra1: LR,  Extra2 : 0

The setting parameter shown above is 'leak rate, date, time, status' read request command example. After write command, the readed value(when read OK) save at 402 ~ 403 (WORD, DWORD, FLOAT memory) and 402 ~ 404 (STRING memory).

 

Write example 4)

PORT:0,  station:0, ADDRESS:0405, Extra1: S32,  Extra2 : 0

The setting parameter shown above is 'operation time of controller' read request command example. After write command, the readed value(when read OK) save at 405 WORD, DWORD, FLOAT, STRING memory.

 

Write example 5)

PORT:0,  station:0, ADDRESS:0406, Extra1: Q1,  Extra2 : 0
