Logic 14A: Partial stop logic applicable for selection of active safety input
devices
Overview (Logic 14A)
For production machines, robots, and the like, a hazard is generally isolated by a protective door
(guard), however, when performing teaching or maintenance, the machine is operated in the
condition that a person is in the danger zone. For such a situation, this logic described is applicable
to the mode selection between Teach mode (maintenance mode) and Auto mode (operating mode).
Safety outputs perform as single channel outputs.
This logic enables the connection of 3 dual channel direct opening inputs, 1 mode select input, and 1
dual channel dependent input.
