Omron C28P-CDR-A

Each Programmable controller is connected in series starting with a CPU and, if required, continuing on with Expansion I/O or Special I/O Units. All other Units are connected in series following the CPU and can be in any order desired except for the I/O Link Unit, which must always come last. Up to five Units, including the CPU can be connected as long as the total number of words occupied does not exceed ten.

The actual number of bits that can be used as I/O bits is determined by the model of the CPU and the PC configuration. There are different models of Expansion I/O Units and Special I/O Units and I/O Link Units which can be connected to any of the CPUs. Each CPU model provides a particular number of I/O bits and each Expansion I/O Unit, Special I/O Unit or I/O Link Unit provides a particular number of I/O bits. Configuration charts for the possible combinations of CPUs and Units are included later in this section. Refer to those to determine the actual available I/O bits.
