ABSTRACT:
An I/O module expansion unit having slots to install I/O modules thereon is provided for a distributed automation system. With the I/O module expansion unit, storing the configuration checksums generated with an algorithm from the software and hardware information of I/O modules, the distributed automation system can simplify the identification of an I/O module. By directly writing the configuration parameters stored in the I/O module expansion unit into the installed I/O module, the distributed automation system can simplify the setting and replacement of an I/O module. The I/O module expansion unit may also fast detect a hot-swap of an I/O module by wiring to the slots.
