Delta DOP Series HMI Connection ManualDOP-A/AE/AS Series
Jetter Nano Series PLC | Back to Table |
A. HMI factory settings
Baud rate: 9600, 8, EVEN, 1
Controller station number: 0. (no PLC station number in protocol, therefore, only 1(HMI) to 1 (PLC) communication is allowed.)
Control area/status area: WR0 / WR10.
NOTE
1)Please notice that no PLC station number in protocol, therefore, only 1(HMI) to 1 (PLC) communication is allowed.
2)Only 1 Bit or 1 Word can be transferred for each communication.
3)In general, each register occupies max. 24 Bits. However, some registers occupies 8 Bits only.
4)Because the initial time of this controller is longer, it is recommended to set HMI startup delay time (Recommended time is 10 seconds).
5)When the register R is used for Double Word device, please set its format as signed format. (The default format in Screen Editor is signed format)

Data

16Bits
24Bits
Only the first 16 bits are used for WRn registers.
Only the first 24 bits are used for Rn registers, the highest 8 bits (Bit 24 ~ 31) are set to 0 by default setting.
NOTE
1) The difference between WRn and Rn:
yWhen using devices that the data length is in Word, only Bit 0 ~ 15 are valid for both of WRn and Rn registers.
yWhen using devices that the data length is in Double Word,
if the read/write address format is set to WRn, the Bit 0 ~ 15 of WRn register is the low word of a read/write value, the Bit 0 ~ 15 of WRn+1 register is the high word of a read/write value.
