Logic 12d: Partial control logic for apparatus with openings
Overview (Logic 12d)
This logic is for constructing partial control of safety devices with dual channel solid state outputs,
such as safety light curtains, for safety protective measures of production machinery, robots. Safety
outputs perform as dual channel outputs.
This logic enables the connection of 1 dual channel direct opening inputs, and 1 dual channel safety
inputs, 3 dual channel dependent inputs.
