6.5 Analog input module SM 331; AI 8 x 14 Bit High Speed; isochrone;
(6ES7331-7HF0x-0AB0)
Order number
6ES7331-7HF00-0AB0 or 6ES7331-7HF01-0AB0
Properties
● 8 inputs in 4 channel groups
● Measurement type programmable for each channel group:
– Voltage
– Current
● Programmable resolution for each group (13 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
● Supports isochronous mode
● Electrical isolation from the CPU
● Electrically isolated from load voltage (not for 2-wire transducers)
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
