Device part of  <Figure 1> input com portCOM4), baud rate( 9600 ), parity bit( 0 ), data bit( 8 ), stop bit( 1 )respectively, accordint to the setting of equipment.

 

Read schedule of SF-2200 Protocol communication driver

Read schedule setting parameters are as follows:

1) station – don't card.

2) read command – Command = SERIAL, TEMP, PRES, CORR, FLOW, BATT.

3) read 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, TEMP, 0, 0, 1,
READ, 0, PRES, 0, 2, 1,
READ, 0, FLOW, 0, 4, 1,

SF-2200 Protocol communication driver store the same data in WORD, DWORD, FLOAT, DOUBLE, INT64 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.
