Standard PLC-5 Processors
- Total I/O, Max. is the actual I/O circuits, regardless of the number of connection points or I/O image bits. The number of I/O image bits (8, 16, or 32) that correspond to an I/O module limit the number of I/O at that module; however, some modules may have less I/O than I/O image bits. This includes local I/O, extended local I/O, and Universal Remote I/O combined. This does not include DeviceNet I/O.
Any mix means that any number of the I/O can be inputs and any number can be outputs, with no placement restrictions.
Complementary means that to configure this many I/O, pairs of modules must have duplicate addresses. This pair must be either 2 output modules sharing the same output image bits or an input module and an output module complementing each other. In either case, module placement must conform to these restrictions. - I/O rack is an I/O addressing unit that can contain a max. of 128 I/O with unique addressing of I/O modules or 256 I/O with duplicate addressing of I/O modules.
