NETWORK ACTIVE I/O MODULE WITH REMOVABLE MEMORY UNIT |
摘要 |
<p>An Active Input/Output (I/O) Module (12) forming a node of an industrial control network includes a housing for mounting a plurality of input and/or output serial data bus connectors (22 and 26), input and output device data connectors (20 and 28), and main and auxiliary power connectors (34), if desired. A programmed microprocessor unit (15) is housed within the housing for controlling data and communication with a system main Programmable Logic Controller, or equivalent. A portion of the memory associated with the microprocessor for storing data specific to the node represented by the I/O module comprises a Removable Memory Unit (18), thus permitting the I/O module to be replaced upon failure with a new I/O module capable of receiving the Removable Memory Unit to re-constitute the I/O module without having to re-program the node-specific data on site.</p> |
