7. Processor Selection Main Difference between models include:
amount of available RAM and Program memory
external communication connections and protocols
cost
After collaborating with Dan Shaughnessy, the base model was determined to meet minimum customer specifications for processor speed, work memory capacity, and external communication setup

8. Processor Module
BMXP best cost effective solution, saves Gleason $600
Connection of HMI via Modbus serial link works since display is nothing more than dummy terminal

9. I/O Connection Interfaces
3 systems analyzed:
Advantys Telefast ABE7 prewired system
Advantys OTB system
Advantys STB system
All 3 systems are capable of handling multiple communication protocols, some which are unnecessary

10. I/O Interface 1
Advantys Telefast ABE7 pre-wired I/O system – simple plug and play solution, requires PLC card with HE10 connector

11. I/O Interface 2
Advantys OTB – communication using CANopen, Modbus and Ethernet each with 20 I/O directly integrated

12. I/O Interface 3
Advantys STB – allows communication via Modbus, Ethernet, CANopen, Devicenet, Profibus, and Interbus. 32 modules can be connected to a single system

13. Recommendation
Advantys Telefast ABE7 pre-wired system offers the most simplicity, power, security, and maintenance for money
System is a direct wire up solution eliminating costly work hours to wire up I/O by hand
Without system 40+ wires stripped by hand where 8-10 wires can be completed/hr
Collaboration with Dan Shaughnessy proved that this system would save the most money and require the least effort to implement in current control setup

14. Advantys Telefast ABE7 options
Many models were analyzed and a choice was made on cost effectiveness, available current output, and mean time before failure (MTBF) for internal relays
Possible Systems: ABE7RS2, ABE7R17T111, ABE7P16T111, ABE7P16T2, ABE7P08T3, ABE7R16T2, and ABE7R16T3

15. Advantys Telefast ABE7 options
After looking at available options, one key criterion was output current rating for each system. Solenoid relays are 30W and require 1.25A to operate. Telefast systems rated at higher currents cost considerably more.
System was chosen to meet minimum current rating while keeping cost down. MTBF was also considered by analyzing graphs.

16. Solution ABE7R16T111 Uses 20-pin HE 10 connector
Uses 5mm ABR7S11 relays rated at 6A
MTBF 1 million cycles
Standard Cost:$450

19. Conclusion
PLC system is complete with processor selection and proposed changes to the digital I/O system
Result: reduction in cost and simplicity
