Direct Logic 205 Analog IO modules. 7 of 12 stencils.
This is a stencil for the security extension of the i* requirements in engineering notation.
This stencil can be used to model state-event-fault-trees. On the one hand, according state machines can be models easily and on the other, it provides skeletons for the event-tree part. It uses the ISO-Icons for AND, OR and NOT.
Six pairs of custom circles with 3, 5, 6, 8, 12, or 16 evenly spaced magnets each, and with either the first magnet, or the first side of the magnet polygon, at the top. For numbers of magnets other than 2, 4 and 8, the OmniGraffle 5 Connections Inspector doesn't allow for radially even distribution of magnets. (The...more
