Table 26: Variables - Job 1 - Danfoss TFX Installation And Operation Manual

5.2.3.4 Jobs
Every time a CAN message is received, jobs are performed
after mapping and before logging.
In the J tab, con gure the calculation operations you
OB S
need for your job.
For the example con guration, you need two jobs with
the function C P
AL CULATE ARAMETER
function, you perform calculation operations and overwrite
interface variables with calculated values.
JOB 1
With the rst job, you check whether the current speed is
above or below the threshold value. If one of these two
cases applies, the V U8 T

to the value 1. This triggers logging of the CAN message.

The buttons for entering the calculation operations have the
following functions:
Buttons Description
C = clear: deletes the entire calculation operation
CE = clear entry: only deletes the last symbol entered
Add variables to the calculation operation.
Click on the button to open a window. Assign xed
values, interface variables, or device variables to the
variables. After you have de ned a variable, the display
on the button jumps to the next variable.
The selected variables are listed under

Basic calculation types (addition, subtraction,
multiplication, division)
and = logical AND link
.
If all linked operands are true or not equal to zero, the
result is operation 1. otherwise, the result is operation 0.
or = logical OR link
If one of the linked operands is true or not equal to
zero, the result is operation 1. otherwise, the result is
operation 0.
If both linked variables are full-number values (integers),
the link is made by bits.
Comparison signs (equal to, smaller than, greater than,
not equal to, smaller or equal to, and larger or equal to)
The result is 1 when the comparison is true.
The result is 0 when the comparison is not true.
