Map safe process signal to variable
43110
The logical device generates a safe process signal. To be able to use this signal in the safety
application it has to be mapped to a variable.
To map the created process signal of a logical device to a safe variable:
►
Select the tab [I/O mapping] in the device editor.
>
Editor window shows table with mapping settings.
►
Enter the name of the variable in the variable field of bit 0 to which the safe process signal is to be mapped.
>
CODESYS uses the entered designation to create a global variable of type SAFEBOOL.
>
Safety application can access the safe process signal via the variable.
The created variable is stored in the global variable list (GVL)
IoConfigRemote_Globals
.
► Always choose an unambiguous name for the variable.
