【英文介绍】
Allen-Bradley SLC 500 Series controllers (5/03 PLC controllers or later) use Allen-Bradley SST-ASI-SLC AS interface scanners for fast and reliable connection to field devices and sensors. The SST-ASI-SLC scanner is installed in the Allen-Bradley Industrial Automation network to provide data access and protocol, Used to connect Allen-Bradley SLC 500 series PLCS to basic binary (on/off) field I/O devices such as feedback sensors, on/off actuators, buttons, rotary encoders, analog inputs, and valve position sensors. The SST-ASI-SLC scanner is capable of connecting Allen-Bradley PLC to 2 separate ASI networks, each of which can have 62 nodes (slave stations). The device supports international standards for such data exchange. It can be easily installed and connected to the PLC backplane, which integrates power and data transmission in a single flat cable. The interface supports AS-Interface peripheral fault detection for diagnosing and switching analog signal values from peripherals. There are 3 diagnostic leds at the top of the module to indicate the overall status of scanner operation, channel 1 and channel 2.
It only requires a certified ASI power supply. Slave devices on the network (which can have up to 3 outputs and 4 inputs) are cyclically polled. The total cycle time is always less than 10 milliseconds. The brain of the device is a Renesas Electronics M16C processor.
