Safe AND with ES bypass and protection against restart
The IO mapper block "Safe AND with ES bypass and protection against restart"
is used for parallel processing of multiple emergency stop signals (ES) and
the protection against automatic restart. The individual emergency stop signals
(ES) can be dynamically masked using bypass signals.
Function
The "SAFE-In_W1" and "In_W2" to "In_W4" inputs are ANDed. Via the optional
bypass inputs SAFE-In_Bypass_W1 and In_Bypass_W2 to In_Bypass_W4, these
inputs can be masked for the AND operation. The result of the AND operation is
connected with the input of the restart lockout block ( ).
If the AND operation of the inputs provides logic "0", the output of the restart
lockout block is set to logic "0”. To set this output to logic "1” again, a 0-1-0
change (with trigger to the falling edge) has to be detected at the In_Start
input.
