MOD-SEL (safety selector)
The MOD-SEL function block verifies the status of
the inputs from a mode selector (up to 4 inputs):
If only one input is 1 (TRUE) the corresponding
output is also 1 (TRUE). In all other cases, and thus
when all inputs are 0 (FALSE) or more than one
input is 1 (TRUE) all the outputs are 0 (FALSE).
Parameters
Input type:
- Double selector Allows connection of two-
way mode selectors.
- Triple selector Allows connection of three-
way mode selectors.
- Quadruple selector - Allows connection of four-way mode selectors.
Filter (ms): This is used to filter the signals coming from the mode selector. The filter can
be configured to between 3 and 250 ms and eliminates any bouncing on the contacts. The
length of the filter affects the calculation of the unit's total response time.
Simultaneity (ms): always active. Determines the maximum permissible time (ms) between
switching of the various signals from the external contacts of the device.
Enable Error Out: If selected reports a fault detected by the function block.
Item description: This allows a description of the component's function to be entered. The
text is displayed in the top part of the symbol.
