When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can read and 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 output contents or data year when DATA, SET command. Note ) 0, 9999 = display controller, other RTU output command.
0 or 9999 – Modern Tech Display – setting of write
DATA, SET command – read of old data, year of data modification request.
other command – don't care.
3) ADDRESS readed data saving start (WORD) address or data month, day.
SET command – month, day of data modification request ( higher 2 digit : month, lower 2 digit : day ),
RESET (RST), SYNC (TSYN ) command – don't care,
other command – readed data saving start (WORD) address.
4) Extra1 write command.
RESET (RST) – reset of controller,
SYNC (TSYN) – time syncronization, ( time syncronization with computer )
CURR – read of current rainfall,
LOG – read of status LOG data,
STS – read of controller status,
TIME – read of current time,
RAIN – read of current rainfall 2 value,
RAIN3 – read of current rainfall 3 value,
RAIN4 – read of rainfall intensity,
RAIN5 – read of the day before rainfall,
VER – read version information.
DATA – read of saved old data : output value = old data hour, minute, ( higher 2digit : hour, lower 2digit : minute )
SET – old saved data modification request.
5) Extra2 data time setting when DATA, SET command.
DATA command – old data read month, day ( higher 2digit : month, lower 2digit : day ),
SET command – hour, minute of data modification request ( higher 2digit : hour, lower 2digit : minute ),
other command : don't care.
Note ) Write command for reading(CURR, LOG, STS, TIME, RAIN, RAIN3, RAIN4, VER, DATA) save the readed data from 'Address' at WORD memory.
The 1st address of saveing data is success flag( 1 : read OK, 0 : read error ).
Note ) Readed value for DATA write command save( 1 hour every data ) at 'Analog Input Tag' of 'Old Data Save Tag'.
