4-38 Revision Apr. 30th, 2007, 2007PDD23000002

$20 = 3A00H Set starting Bit. Because the value of high byte and low

byte will be exchanged when HMI sends command, even

though the starting Bit is 3A when sending data, it is

needed to input 3A00.

$28 = 0A0DH Set end Bit. Because the value of high byte and low byte

will be exchanged when HMI sends command, even

though the end Bit is 0D0A when sending data, it is

needed to input 0A0D.

$50 = PUTCHARS($20, 18, 500) Start to send data from $10, the data length is 18 bytes

and the timeout setting is 500ms.

$51 = GETCHARS($110, 18, 500) Receive the PLC response data after communication. The

received data is stored in $100, the data length is 18 bytes

and the timeout setting is 500ms.
