| <Figure 1> Read setting example of Sunny Net driver |
Device part of <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively.
If you want to communicate by using Ethernet module, set the device settings as UDP/IP, IP, Service port(24272).
In protocol option part, you can set the following: station number of computer(source) (0 ~ 65535, Default = 0 ), whether to use synchronization code(0 = Not use, 1 = Use, Default = 0) for power line communication, whether to use SMA Net Frame(0 = Not use, 1 = Use, Default = 0 ), device type number(0 = Default, 1 = SCC, 2 = SBC+, Default = 0 ), delay time for each packet when using multi packet(0 ~ 5000 mSec, Default = 0), delay time after Time Sync(10 ~ 3000 mSec, Default = 10). Each argument is a comma-delimited( , ).
You can set station number, baud rate, etc by front control button.
Note) When you using 'Sensor Box', the delay time after Time Sync should be set '170 or over'.
Sunny Net communication driver's read schedule
Read schedule setting parameters are as follows:
1) Device Number – The set Address(0 ~ 65535) of Sunny Boy device.
2) Read Command – Fixed to 11(data read).
3) Read Start Address – Don't care.
4) Save Start Address for Communication Server - Saving start address of Communication Server.
5) Read Size – Always fixed to 1.
6) Read Data Save Method – 0 : Save as type of Normal, SBC and SCC+,
1 ~ 255 : Set the save method for read data at WorkDirectory\SCAN\CH_INFO%03d.ini file. (Refer to <Table 4>)
Read schedule example)
READ, FFh, 11, 0, 0, 1,
<Table 1> ~ <Table 3> are order and contents to save read value of Default, SCC and SBC+ device type which are read by 11(data read) command to communication memory.
