Here is an expanded introduction in English based on the provided content about the Omron CS1W-BC082 CPU Backplane:

The Omron CS1W-BC082 is an 8-slot CPU backplane designed for use with the CS Series programmable logic controllers (PLCs). This backplane accommodates up to eight modules but does not include the CPU or power supply units. It is exclusively compatible with CS Series PLC modules.

For large-scale control applications, the CS1 system supports flexible expansion configurations. Two expansion unit series can be connected over distances of up to 50 meters, allowing for long-distance extension. This configuration can include up to 72 units and 7 devices. Alternatively, within a 12-meter range, the system can support up to 80 units and 7 devices, meeting demanding control requirements.

To achieve long-distance expansion, an I/O Control Unit and multiple I/O Interface Units can be used to connect two series of CS1 expansion units. These expansion units can each extend up to 50 meters, and the combined system can include up to 72 units and 7 devices. CS1 Basic I/O Units, CS1 High-function I/O Units, and CS1 CPU Bus Units can be installed in any slot within the expansion system without requiring special remote programming procedures.

Note: C200H units are not supported for installation in long-distance expansion systems.
