Additional information to SM 331; AI 8 x 13 Bit

Unused channels
For unused channels, set the "disabled" instruction at the "measuring method" parameter.
This reduces the module's cycle time.
Link the M- terminals of the unused channels with one another.
6.7 Analog input module SM 331; AI 8 x 12 Bit;(6ES7331-7KF02-0AB0)
6.7
Order number
6ES7331-7KF02-0AB0
Properties
● 8 inputs in 4 channel groups
● Measuring method adjustable per channel group
● Resolution adjustable per channel group (9/12/14 bits + sign)
● Measuring range selection any, per channel group
● Programmable diagnostics and diagnostic interrupt
● Limit value monitoring adjustable for 2 channels
● Hardware interrupt can be set when limit exceeded
● Electrically isolated to CPU and load voltage (not for 2-wire transducers)
Resolution
The measured value resolution is directly proportional to the selected integration time, i.e.
the measured value resolution increases in proportion to the increase in the length of the
integration time at the analog input channel.
Diagnostics
For information on diagnostics message consolidated at the "group diagnostics" parameter,
refer to the table
