Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to controller.
In protocol option part, you can set 'Write after delay time'( 0 ~ 5000 , default = 1000 mSec ).
Note) Please refer Chapter 4 the baud rate setting.
KEYENCE RD Series communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – Don't care.
2) Read command – Command = M – read of current measurement.
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. ( H – 5, M - 1 )
Read schedule example)
READ, 0, M, 0, 0, 1,
KEYENCE RD Series communication driver store the same data in WORD, DWORD, FLOAT, STRING memory, but the data format are different.
If you click the icon 
in protocol option part at
<Figure 1>, you
can see the dialog box such as <Figure 2>. you can also set read schedule by
using this part.

You can set read schedule by using 
, 
, 
button and listbox of <Figure
2>.
Also, you can set 'Write after delay time' by using the part of 'Write After Sleep' of <Figire 2>.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can read, write by using 'writing settings'.
Digital Write
Digital write and analog write have the same setting parameters except output value.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Data saving start address when M, SR, J0 ~ J17 command. (Read, refer to <Table 1>)
4) Extra1 Command.
M, SR, J0 ~ J17 : read command,
AA0, AA1, ¡¦ : write command. ( refer to <Table 1>)
5) Extra2 Writing value or type of output value when I, SD command.
I : writing Span value. ( -9999 ~ 9999, 0 = don't use writing value )
SD : type of output value. ( 0 = HH value, 1 = HI value, 2 = LO value, 3 = LL value )
