At the pin assignment above you can see how the sensors are to be connected at 2, 3
respectively 4 wire measurement.
n
With every channel a 2 wire measurement may be performed.
n
3 wire measurement is only possible via the channels 0 and 1.
–
Please consider with 3 wire measurement that the corresponding channel is
always deactivated in the parametrization. The corresponding channel of channel
0 is channel 2 and of channel 1 is channel 3. Not used channels must always be
de-activated in the parametrization.
n
4 wire measurement is only possible via the channels 0 and 1.
–
The measurement current for channel 0 is applied at pin 1 and 2. The measure-
ment for channel 0 happens at pin 3 and 4. The analog value for channel 0 is rep-
resented in input word 0.
–
The measurement current for channel 1 is applied at pin 5 and 6. The measure-
ment for channel 1 happens at pin 7 and 8. The analog value for channel 1 is rep-
resented in input word 1.
–
Please consider with 4 wire measurement that the corresponding channel is
always deactivated in the parametrization. The corresponding channel of channel
0 is channel 2 and of channel 1 is channel 3. Not used channels must always be
de-activated in the parametrization.
At CPU, PROFIBUS and PROFINET the input respectively output area is embedded to
the corresponding address area.
IX - Index for access via CANopen with s = Subindex, depends on number and type of
analog modules
SX - Subindex for access via EtherCAT with Index 6000h + EtherCAT-Slot
More can be found in the according manual of your bus coupler.
