Measurement With Up To 12 Channels; Forming Groups Of Temperature Sensors - Siemens SINAMICS S120 Function Manual

Measurement with up to 12 channels

Temperature measurement with two 2-wire sensors
With p4108[0...5] = 1 you can acquire the signals from two sensors in 2-wire technology. The
first sensor is connected to terminals 1 and 2. The second sensor (number = first sensor + 6)
is connected at terminals 3 and 4. You can find additional information in function diagram
9627 in the SINAMICS S120/S150 List Manual.
When connecting two 2-wire sensors to terminal X531, the first sensor is assigned to
temperature channel 1. The second sensor is assigned to channel 7 (1+6).
Up to 12 temperature sensors can be connected to a TM150.
Note
Connection diagram for 12 temperature channels
The temperature sensors connected to a TM150 are not numbered consecutively. The first 6
temperature channels retain their numbering of 0 to 5. The other 6 temperature channels are
consecutively numbered from 6 to 11, starting at terminal X531 (see function diagram 9627
in the SINAMICS S120/S150 Lists Manual).
Example of 8 temperature channels:
2x2 conductors at terminal X531: p4108[0] = 1 ≙ sensor 1 is at channel 0 and sensor 2 is at
channel 6
2x2 wires at terminal X532: p4108[1] = 1 ≙ sensor 1 is at channel 1 and sensor 2 is at
channel 7
1x3 wires at terminal X533: p4108[2] = 2 ≙ sensor 1 is at channel 2
1x3 conductor is at terminal X534: p4108[3] = 2 ≙ sensor 1 is at channel 3
1x4 conductor is at terminal X535: p4108[4] = 3 ≙ sensor 1 is at channel 4
1x2 conductor is at terminal X536: p4108[5] = 0 ≙ sensor 1 is at channel 5

Forming groups of temperature sensors

You can combine the temperature channels to form groups using parameter p4111[0...2].
For each group, the following calculated values are provided from the temperature actual
values (r4105[0...11]):
● Maximum: r4112[0...2], (index 0,1,2 = group 0,1,2)
● Minimum: r4113[0...2]
● Average value: r4114[0...2]
