with a Modbus TCP/IP network through a
gateway
 Ethernet Modbus/TCP, BOOTP/DHCP, FDR
 Memory:
 RAM = 4096Kb,
 Program = 3584 Kb,
 Memory Card = 8 Mb
 Standard Cost: $1830
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
Processor Module
 BMXP341000 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
 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
I/O Interface 1
 Advantys Telefast ABE7 pre-wired I/O
system – simple plug and play solution,
requires PLC card with HE10 connector
I/O Interface 2
 Advantys OTB – communication using
CANopen, Modbus and Ethernet each with
20 I/O directly integrated
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
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
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
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.
Solution
 ABE7R16T111
 Uses 20-pin HE 10
connector
 Uses 5mm
ABR7S11 relays
rated at 6A
 MTBF 1 million
cycles
 Standard
Cost:$450
Updated Parts List
Conclusion
 PLC system is complete with
processor selection and proposed
changes to the digital I/O system
 Result: reduction in cost and
simplicity
