5.1.2
Input "Measurement start / Test job start"
This PLC command causes the SND40 to start a measurement. This function is available via the
Fieldbus and the parallel interface. The measurement can be made in the program / operating
status Automatic / Ready and Set-up / Edit.
5.1.3
Input "Program selection"
Via the PLC interface the programs 1 to 31 can be selected binary coded. In addition, the signals
M1 to M16 are used.
Pattern for the binary coding
Program 0
Program 1
Program 2
Program 3
...
Program 31
The program is taken over with the signal "program selection". The program selection fails, if
a)
program No.0 is selected
b)
the selected program is missing
c)
or the selected program contains inadmissible parameters.
Case a) the failure message "selected program No. is 0 (invalid)" is shown, the program will not be switched. Via the bus
the fault code 14 is set.
Case b) the failure message "program parameter index 1 invalid" is shown, or fault code 20 via the bus. The program
switch to the desired program is not executed. The currently active program becomes deactivated. The program number via
bus is not changed.
Case c) the failure message "program parameter index xxx" is displayed or fault code 20 via the bus. The program switch
to the desired program is executed.

Sensor cable broken
PLC program number is incorrect e.g. 0
Speed measurement not possible
Sensor short circuit
Leak flux module defect
PLC program not implemented
Fan defect

Note:
The SND40 has 32 programs in the program memory.
Program 32 cannot be selected, but it can be used as backup memory.
