Overview o o o Processor Module Options and Selection External I/0 Connection Interfaces and Selection Updated parts List

Processor Module 1 o o o BMXP 341000: Base Model Integrated Communication Port: Serial RTU/ASCII Modbus communication with master/slave mode and speed up to 19. 2 Kbps Memory: n n n o RAM = 2048 Kb, Program = 1792 Kb, Memory Card = 8 Mb Standard Cost: $585

Processor Module 2 o o BMXP 342010: Upgraded Model Integrated Communication Port: n n o Memory: n n n o Serial RTU/ASCII Modbus communication with master/slave mode and speed up to 19. 2 Kbps CANopen Master allows devices to communicate with a Modbus TCP/IP network through a gateway RAM = 4096 Kb, Program = 3584 Kb, Memory Card = 8 Mb Standard Cost: $1235

Processor Module 3 o o BMXP 342020: Upgraded Model Integrated Communication Port: n n o Memory: n n n o Serial RTU/ASCII Modbus communication with master/slave mode and speed up to 19. 2 Kbps Ethernet Modbus/TCP, BOOTP/DHCP, FDR RAM = 4096 Kb, Program = 3584 Kb, Memory Card = 8 Mb Standard Cost: $1550

Processor Module 4 o o BMXP 342030: Upgraded Model Integrated Communication Port: n n o Memory: n n n o CANopen Master allows devices to communicate with a Modbus TCP/IP network through a gateway Ethernet Modbus/TCP, BOOTP/DHCP, FDR RAM = 4096 Kb, Program = 3584 Kb, Memory Card = 8 Mb Standard Cost: $1830

Processor Selection o Main Difference between models include: n n n o 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

Processor Module o o BMXP 341000 best cost effective solution, saves Gleason $600 Connection of HMI via Modbus serial link works since display is nothing more than dummy terminal

I/O Connection Interfaces o 3 systems analyzed: n n n o Advantys Telefast ABE 7 prewired system Advantys OTB system Advantys STB system All 3 systems are capable of handling multiple communication protocols, some which are unnecessary

I/O Interface 1 o Advantys Telefast ABE 7 pre-wired I/O system – simple plug and play solution, requires PLC card with HE 10 connector

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

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

Recommendation o o Advantys Telefast ABE 7 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

Advantys Telefast ABE 7 options o o 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: ABE 7 RS 2, ABE 7 R 17 T 111, ABE 7 P 16 T 2, ABE 7 P 08 T 3, ABE 7 R 16 T 2, and ABE 7 R 16 T 3

Advantys Telefast ABE 7 options o o After looking at available options, one key criterion was output current rating for each system. Solenoid relays are 30 W and require 1. 25 A 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.

Solution o o o ABE 7 R 16 T 111 Uses 20 -pin HE 10 connector Uses 5 mm ABR 7 S 11 relays rated at 6 A MTBF 1 million cycles Standard Cost: $450

Updated Parts List

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