About the 8055-SCP-654R
The 8055-SCP-654R is a Model 650 Processor unit designed and produced by Square D as part of the SY/MAX 8055 series of processors.
The 8055-SCP-654R is a single-shot processor that has a built in ThinWire Ethernet communication port. Along with that, the 8055-SCP-654R processor will support software that runs on a host computer. The 8055-SCP-654R processor is designed to be able to handle high-speed information transfers between the computer applications and the manufacturing floor. Outfitted with a very powerful instruction set, the 8055-SCP-654R processor can handle upwards of 8000 I/O in mid-sized to large-sized control applications.
The 8055-SCP-654R processor has eight vertically line-up LED status indicators on the faceplate. The “RUN,” LED light, which is the top one, is green, while the other eight ones have a red color. The last seven red lights are as follows from top to bottom: “HALT,” “MEMORY,” “FORCE,” “I/O,” “BATTERY LOW,” “WRITE PROTECT,” and “PEER COMM ERROR.” Below these LED indicators lies a small door that houses the 8055-SCP-654R processor’s battery. Below this battery compartment, there is a small key switch that has four positions: “RUN PROGRAM,” “RUN,” “HALT,” and “DISABLE OUTPUTS.”
The Model 650 processor units must be physically installed into a SY/MAX digital or register rack. To install, put a lithium battery inside the battery door, tightening the door with a screw upon successful positioning of the battery. Next, ensure that the rack you are installing the processor into is mounted in an area where the temperature will not exceed 140 degrees Fahrenheit or 60 degrees Celsius. Also, make sure that the rack is mounted in such a way that the Model 650 processor will be installed vertically.
