Analog Input Module Sm 331; Ai 8 X 16 Bit; (6Es7331-7Nf00-0Ab0) - Siemens SIMATIC Manual

6.3

Analog input module SM 331; AI 8 x 16 bit; (6ES7331-7NF00-0AB0)

Order number
6ES7331-7NF00-0AB0
Properties
● 8 inputs in 4 channel groups
● Programmable measurement type at each channel group
– Voltage
– Current
● Programmable resolution for each channel group (15 bits + sign)
● Any measuring range per channel group
● Programmable diagnostics and diagnostic interrupt
● Programmable limit value monitoring for 2 channels
● Programmable hardware interrupt when limit is exceeded
● High-speed update of measured values
● Electrically isolated to the CPU
● Supports parameter reassignment in RUN
Resolution
The resolution of measured values is independent of the selected integration time.
Diagnostics
For information on diagnostic messages at the "group diagnostics" parameter, refer to the
table
Hardware interrupts
Hardware interrupts for channel groups 0 and 1 can be programmed in
set a hardware interrupt only for the first channel of a channel group, that is, either at
channel 0, or at channel 2
