Safe Position Detection with PCV100-F200-B17-V1D-6011
Software
The parameters for the program module must be configured as follows:
Inputs
Reader distance and hysteresis
In practical terms, the distance is determined from the difference between the two measured
values from the master reader and control reader. The Abstand_Hyst hysteresis is the
compensation needed in case the readers move mechanically, e.g. in curves.
Outputs
Use of Safe Signals
Figure 4.5
Network of position safe "F_Safepos_"
Freigabe
BOOL
Release of the function; the main function is activated
using the "CodeSprung" output
Wert_M
DINT
Position value of the master reader
Wert_K
DINT
Position value of the control reader
Abstand
DINT
Mechanical distance between the master reader and
control reader in mm (max. 5000 mm)
Abstand_Hyst
DINT
Permissible tolerance of the reader distance in mm
(max. 30 mm)
CodeSprg_Anfan
g
DINT
Last code position before the code jump; in the
example, activated with the value from DB. The
numerical value can also be entered directly
CodeSprg_Ende DINT
First code position after the code jump; in the example,
activated with the value from DB. The numerical value
can also be entered directly
S_OK
BOOL
Position is safe
Plaus_F
BOOL
Plausibility error; the parameters "Abstand",
"Abstand_Hyst", or "Wert_Offs" are outside of the
defined limit values
