“Safe AND”
The IO mapper block “Safe AND“ is used to additionally map activation sig-
nals [mode selection signal (MS), enabling control signal (EC), SMMx signal
(A_SSMx)] to other, also functional, signals from the machine/installation.
The output of the block can be used to control the operating states [normal
operation, Safe stop (SMST1 and SMST2), Safe motion (SMM1 to SMM16)],
the holding brake and/or the locking of the safety door locking device.
Function
Logic AND operation of the inputs SAFE-In 1, In 2, In 3 and In 4. At least 2
inputs have to be used; apart from that, two optional inputs are available. The
status TRUE is internally pre-assigned to optional inputs that are not used.
