6.10 Analog input module SM 331; AI 8 x TC; (6ES7331-7PF11-0AB0)
Order number
6ES7331-7PF11-0AB0
Properties
● 8 inputs in 4 channel groups
● Programmable measurement type at each channel group
– Temperature
● Programmable resolution at each channel group (15 bits + sign)
● Any measuring range selection per channel group
● Programmable diagnostics and diagnostic interrupt
● Programmable limit value monitoring for 8 channels
● Programmable hardware interrupt when limit is exceeded
● High-speed update of measured values at up to 4 channels
● Programmable hardware interrupt at end of cycle
● Electrically isolated from the CPU
● Supports parameter reassignment in RUN
Resolution
The resolution of measured values is independent of the selected integration time.
Diagnostics
For information on diagnostics messages at the "group diagnostics" parameter, refer to
chapter Diagnostic messages of analog input modules (Page 296).
Hardware interrupts
Hardware interrupts for channel groups 0 and 1 can be programmed in STEP 7 . However,
set a hardware interrupt only for the first channel of a channel group, that is, either at
channel 0, or at channel 2
Terminal assignment
The diagrams below show various wiring options. These examples apply to all channels
(channel 0 to 7).
