For pt.VI see ibid., vol.40, no.10, p.AK137 (1985). Principles are described for binary and hexadecimal codings, and for a basic circuit for a fast astable multivibrator. The latter is used with a programmable logic controller (PLC) to switch alternately between program and I/O data. Details are portrayed for occupied/vacant locations in an automatic vehicular parking system. Advantages claimed for PLCs are reliability, flexibility, short installation time and rapid loop data transfer.
