Connection diagram for 12 temperature channels
The temperature sen
sors 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.
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 conductor at terminal X532: p4108[1] = 1 ≙ sensor 1 is at channel 1 and sensor 2 is
at channel 7
● 1x3 conductor at terminal X533: p4108[2] = 2 ≙ sensor 1 is at channel 2
● 1x3 conductor at terminal X534: p4108[3] = 2 ≙ sensor 1 is at channel 3
● 1x4 conductor at terminal X535: p4108[4] = 3 ≙ sensor 1 is at channel 4
● 1x2 conductor at terminal X536: p4108[5] = 0 ≙ sensor 1 is at channel 5
Forming groups of temperature sensors
Using p4111[0...2], temperature channels can be combined to form groups. 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]
Example:
The temperature actual value from channels 0, 3, 7, and 9 should be combined in group 1:
● p4111[1].0 = 1
● p4111[1].3 = 1
● p4111[1].7 = 1
● p4111[1].9 = 1
The calculated values from group 1 are available in the following parameters for
interconnection:
● r4112[1] = maximum
● r4113[1] = minimum
● r4114[1] = average value
