Abstract
A programmable controller has input and output multiplexer modules through which I/O data may be transferred. A multiplexer array is stored in the controller memory for storing this I/O data and conventional programmable controller instructions in the user control program may be employed to examine or set specified bits in the stored array. The multiplexer module may take the form of two separate modules in which one module generates a select code to a matrix of switches or operating devices and the other module transfers data to or from a selected row in the matrix.
