configuration of AI523(AC500)
In configuration of AI523, for example for AI0 we have two variable. one of them is analog input I0+(type is INT)and other is digital input I0+(type is BOOL),also about other eg , AI0.....15.
whats the usage of digital input I0+?
what i have to do for setting this input analog for pt100?
For each channel of AI523 Analog Input Card, you have two possibilites of usage:
i)You can use as an analog channel.
ii)You can use as a digital channel.
If you set the configuration of channel as Digital Input, related channel behaves like an Digital Input.
If you want to use Analog Input channel for PT100 you have to configure channel as PT100 2 wire or PT100 3 wire.
For more detail, please see attached picture.
Hope it helps you.
