1. Read settings

 

<Figure 1> is read setting example of Soleaf PCS(Dass Tech) communication driver.

<Figure 1> Read setting example of Soleaf PCS(Dass Tech) 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 device.

Also, you can input whether to confirm check sum of read data(1 : Use, 0 : Not use, Default = 0) at Option part.

 

Notice) Check sum is only used at inverter device of high capacity.

 

Soleaf PCS(Dass Tech) driver's read schedule

Read schedule setting parameters are as follows:

1) Device ID Number – ID number between 0 and 255.

2) Read Command – Set among MOD, ST1, ST2, ST3, ST4, ST5 and ST6. (Refer to <Table 1>)

3) Read Start Address – Don't care. (Set as 0)

4) Save Start Address for Communication Server - Saving start address of Communication Server.

5) Read Size – Always fixed to 1. Fixed according to read command. (Refer to <Table 1>)
