GOALS

ImplementationHardware Programmable Logic Controllers (PLCs) - Standardized on Allen-Bradley SLC and Micrologix controllers

ImplementationHardware Programmable Logic Controllers (PLCs) - Standardized on Allen-Bradley SLC and Micrologix controllers MAS/MDS radios and modems for Radio Communication

ImplementationHardware Programmable Logic Controllers (PLCs) - Standardized on Allen-Bradley SLC and Micrologix controllers MAS/MDS radios and modems for Radio Communication Mille Research modems for Phone Line Communication

ImplementationSoftware Standardized on Rockwell Software RSLogix for programming RSLinx for communications RSView for Operator Interface RSMessenger for Alarm Paging LapLink Software allows connection to operator workstation from a remote computer through a dial-up modem

ImplementationExpandable and Flexible System must be easily expandable Implement additional sites without plant shutdown Allow for additional I/O and control philosophy changes System must be flexible Allow for a variety of communication interfaces Allow for a variety of instrumentation
