SP117337_Ring Loader.prg is the ring loader. It operates as the master. It sends commands telling RUISRVUP_Form Tool.PRG to form rings and waits for a signal that the form tool i s out of the way. The communication happens with ethernet. The windows graph application "Informtool Graph" serves as a slave that reports an over force to RUISRVUP_Form Tool.PRG. Please note that because "Informtool Graph" is running in windows it is not a de terministic system and the vendor should make this program run in a real time Op erating System.
