| <Figure 1> Read Schedule setting example of PowerSync 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 setting of controller.
PowerSync communication driver¡¯s read schedule
Read schedule setting parameters are as follows:
1) STATION – 0 ~ 15 station number of compressor.
2) Read command – don't care.
3) Read start address – don't care.
4) Save Start Address for Communication Server – Input save start address of communication server.
5) Read Size – fixed to 74 word. ( refer to <table 1> )
Read schedule example)
READ, 0, 0, 0, 0, 74,
READ, 1, 0, 0, 100, 74,
READ, 2, 0, 0, 200, 74,
