"SLI_PROC_C" block
The "SLI_PROC_C" block simulates the process value ("inputValue") of the rising
temperature of a plant. The block "SLI_PROC_C" contains the manipulated variable of the
controller ("outputValue) and simulates the temperature behavior of the process. This
temperature is fed as process value ("inputValue") into the controller.
A change in the values of the "resetAll" tag (of the comRst parameter) has the following
effects:
Parameter comRst
("resetAll")
The instruction "PID_Compact" is
running
The instruction "PID_Compact" was
stopped
comRst ("resetAll")
remains set to the value
"FALSE"
The "SLI_PROC_C" block outputs a
new process value ("inputValue")
based on a manipulated variable
("outputValue").
The "SLI_PROC_C" block does not
receive a manipulated variable >
"0.0", but it still outputs a new pro-
cess value > "0.0".
comRst ("resetAll"):
Change from "FALSE"
to the value "TRUE"
Both manipulated variable ("output-
Value") and output process value
("inputValue") are reset to "0.0".
The output process value ("input-
Value") / the temperature of the
"SLI_PROC_C" block is reset to
"0.0".
comRst ("resetAll"):
Change from "TRUE" to
the value "FALSE"
Temperature control starts again. The output process value / the tem-
perature ("inputValue") remains
"0.0".
