3.1.1 System Block Diagram Description
{ The System construction provides programming and data collection control for up to 32
spindles through the use of a single optional User Console or Printer Interface Unit (PIFU).
{ Communication for up to 32 Axis Units (Spindle Controllers) is accomplished via an RS422
Daisy chain connection on the front of each Axis unit.
{ A PC with an RS422 interface may be used for Axis unit programming as well as for data
collection and printing functions.
{ A PIFU may be used as a means to provide output data to a printer or host data collection
device.
{ Discrete 24 VDC true low I/O on the Axis unit provide direct communications with the PLC
for individual spindle control or for PLC controlled multiple spindle syncronous fastening
operations.
{ Tool assemblies connect to their respective Axis Controller Units via a set of three homerun
cables: Motor, Encoder, and Sensor / Preamp (Transducer) cables.
