Revision January, 2008, Doc. Name: 2007PDD23000007 

Baud rate: 9600, 8, EVEN, 1 (RS-232). 

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. 

 

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)

24 Bits 

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. 

(24-bit Integer :  If in decimal format, the range is -8388608 ~ +8388607. If in hexadecimal format, the range 

is 0x000000 ~ 0xFFFFFF.) 

  

1)  The difference between WRn and Rn: 

y

 

When using devices that the data length is in Word, only Bit 0 ~ 15 are valid for both of WRn and 

Rn registers. 

y

 

When 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.
