An alternative to the practice of accessing external sense lines and relays at the individual bit level, it treats the sense lines as a 12 bit integer and the relays as a 6 bit integer. The status of the 12 bits can then be read as a decimal number between 0 and 4095 and the relays controlled by outputting a decimal number between 0 and 63. Any combination of bits may then be controlled by these integers. An input pattern can be decoded to give individ- ual bits and an output pattern set up using the decimal equivalents of the bit pattern.
