Introduction to 6ES7331-7KF02-0AB0
SIMATIC S7-300, ANALOG INPUT SM 331, OPTICALLY ISOLATED, 8AI, RESOLUTION 9/12/14 BITS, U/I/THERMOCOUPLE/RESISTANCE INTERRUPT, DIAGNOSTICS; 1X20PIN REMOVE/INSERT W. BACKPLANE BUS
Properties of 6ES7331-7KF02-0AB0
● 8 inputs in 4 channel groups
● Programmable measurement type at each channel group
– Voltage
– Current
– Resistance
– Temperature
● Programmable resolution at each channel group (9/12/14 bits + sign)
● Any measuring range selection per channel group
● Programmable diagnostics and diagnostic interrupt
● Programmable limit value monitoring for 2 channels
● Programmable hardware interrupt when limit is 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, that is, the measured value resolution increases in proportion to length of the integration time at the analog input channel.
Diagnostics
For information on diagnostics messages at the "group diagnostics" parameter, refer to chapter Diagnostic messages of analog input modules.
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 The input impedance depends on the
setting of the measuring range module, see table Measurement types and ranges.

Note
• "Resistance measurement" is only available at one channel per group. The "2nd" channel of the group is used accordingly for current measuring mode (IC). The "1st" channel of the group returns the measured value. The "2nd" channel of the group is assigned the default overflow value "7FFFH."
• There is no compensation for power resistors for "2- and 3-wire connections".
Wiring: Thermocouples with external compensation
Insert a bridge between Comp+ and MANA when using the internal compensation.

this case, you must ensure that low-resistance equipotential bonding is in place so that
the permitted common-mode voltage is not exceeded.
• Interconnect M- and MANA when using non-grounded thermocouples

Measurement types and ranges
Introduction
Module SM 331; AI 8 x 12 Bit has measuring range modules
The measurement type and range is configured at the "measuring range" parameter in STEP 7.
The default setting of the module is "voltage" measurement with "± 10V" range. You can use these default settings without having to program the SM 331; AI 8 x 12 Bit in STEP 7.
Measuring range modules
You may have to change the position of the measuring range modules to suit the measurement type and range (see the chapter Setting the measuring types and ranges of analog input channels ).
The necessary settings are also available on the module's imprint. Mark the position of the measuring range module on the front door.
Additional information on SM 331; AI 8 x 12 Bit
Unused channels
As certain programmed inputs may remain unused due to the channel group configuration,make allowances for the special features of these inputs outlined below in order to be able to use the diagnostics functions at these used channels:
● Voltage measurement (except 1 V to 5V) and for thermocouples: Short-circuit unused channels and connect these with MANA. This optimizes interference immunity of the analog input module. Set the "disabled" value at the "measurement type" parameter for unused channels. This setting reduces module cycle times. Also short-circuit the COMP input if this is not used.
● Measuring range 1 V to 5 V: wire the used and unused inputs of the same channel group in parallel.
● Current measurement, 2-wire transducer: There are two options of wiring the channel circuit.
a) Open unused input; channel group diagnostics disabled. If you were to enable diagnostics, the analog module would trigger a single diagnostic interrupt, and light up its SF LED.
b) Loading the unused input using a 1.5 kΩ to 3.3 kΩ resistor. This allows you to enable diagnostics for this channel group.
● Current measurement 4 mA to 20 mA, 4-wire transducer: wire the unused inputs of the same channel group in series.
All channels deactivated
If you disable all input channels of the module and enable diagnostics at the parameters of SM 331; AI 8 x 12 Bit, the module does not report "external auxiliary voltage missing."
Line continuity check for the 4 mA to 20 mA measuring range
If you configured a measuring range of 4 mA to 20 mA, and enabled the line continuity check, the analog input module logs a wire-break event to diagnostics data when the current drops below 3.6 mA.
The module also triggers a diagnostics interrupt if this function is enabled in the program.A wire break can only be signaled by means of the lit SF LED and the diagnostic bytes must be evaluated in the user program if diagnostics interrupts are disabled.
If you configured a measuring range of 4 mA to 20 mA, disabled the line continuity check,and enabled diagnostic interrupts, the module triggers a diagnostic interrupt when the underflow value is reached.
Line continuity check
The line continuity check is designed only for temperature measurements (thermocouples and thermoresistors.)
