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.
DPTH-100T Inverter communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – Controller address = 0 ~ 255.
2) Read Command – Command = DATA. ( Refer to <Table 1> )
3) Read Start Address – Don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Fixed to 1. ( Refer to <Table 1> )
Read schedule example)
READ, 1, DATA, 0, 0, 1,
<Table 1> is data saving address and contents of DPTH-100T Inverter communication driver.
<Table 2> is each bit status of 'Status' and 'Fault' value.
