Writing Screen Data to the IS-300CR
To update the screen data, user must first populate every individual screen data tag with the validated
data value. User may also perform a screen data read request and then modify / update only the value
of the tag that the user wants to change.
For example, to update the data tag ‘screen1Data.par19_offTime’ value from ‘4500’ to ‘5000’, user must
have these tags populated:
This is always hardcode = 1 since there is only device #1 of
IS-300CR
ioControl.par.scheduleNumber = ‘001’
ioControl.par.screenNumber = ‘01’
screen1Data.par19_offTime = ‘5000’
Update the tag data with new data value
Screen1Data.parXXXX = XXXXX
Update the rest of the tags with new data value
ioControl.com.prepareWriteData = ‘1’
Optional if you only want to populate the
ioControl.par.dataToWriteToIS800
ascii buffer for preview
and debugging purpose.
and finally set the write request flag to 1 to write screen data to IS-300CR:
ioControl.com.writeToIS800 = 1
Once the screen data is written successfully, the ‘ioControl.com.writeToIS800’ write request flag will be
reset back to 0. Make sure to monitor for the ‘ioControl.com.writeNakError’ status tag for any failure
if value > 0.
