Macro Restart Monitored (Max Number = 16) - Reer MZERO Installation, Use And Maintenance Manual

Parameters
Input Logic: enables the selection of the number of logic inputs (from 1 to 7). Selecting 1 the logic
will not be considered.
Select Logic: enables the selection of one of the following types of operator:
AND, NAND, OR, NOR, XOR, XNOR.
Restart Input Logic: enables the selection of the number of inputs for restart logic (from 1 to 7). If
you select 1 the logic will not be considered.
Restart Select Logic: enables the selection of one of the following types of operator for restart
logic: AND, NAND, OR, NOR, XOR, XNOR.
Enable Clear: If selected, enables an input to reset the memorization.
Enable Out: If selected activates an output with the result of the calculation done by the input
logic.
Restart request: If selected, it enables an output that can be used to signal the possibility of
performing the Restart. The behaviour is represented in the truth table.

MACRO RESTART MONITORED (max number = 16)
