What Is Important?
DMC Core Values
1. Accuracy (Flow Meter)
Accuracy(Flow
Meter)
1. Need flow measurements to be very accurate
2. Variety of Flow Meters based on conditions
3. Different Flow Meters have different interfaces to Controls
Key Features
2. Remote Connectivity
Remote Connectivi
ty
1. Data is always collected by central station
2. Data connection is not always reliable
3. Need multiple interfaces to provide for different customer standards
DMC Core Values
3. Cost
Cost
1. Transfers money, but can’t cost much of it
2. Competition drives down cost
3. Lowest Cost usually makes the decision
Key Features
4. Controls
Controls
1. Reliability!
2. Need items that are quick and easy to configure
3. Need items with a range of communication options
4. Remote connectivity is hugely desired
Case Study
Project Requirements Configurable for Multiple Flow Meters
Variety of Communication Options
Local Control for Operator
Remote Monitoring
Availability for Expansion for Remote Connectivity
Low Hardware Costs
Customer ownership for future changes
Motivation for Change Current Solution
AB MicroLogix PLC Panel View Component HMI Different Versions of Code for
Different Flow Meters
Solution S7-1200 Comfort Panel Common Code Base for a
Variety of Flow Meters. Single PLC for variety of
different customer connections.
Which PLC?
The S7-1200 Communication/Remote
Connection Profinet, Modbus TCP, Ethernet,
Ethernet/IP on board Expansion for Modbus RTU,
Profibus, AS-Interface, and others
Cost Lower cost than most
competitor products Onboard IO helped drop overall
cost Common Code Base
Able to develop code to meet a
variety of different meters and sensors.
The S7-1200 Web Server
Web Server with data tables to provide remote troubleshooting
SMTP Option to add in emails
based on events PLC Data Logging
Built in Logging Functionality on the PLC (accessible via webserver)
Not implemented, but an option for growth.
Which HMI?
Comfort Panel Configurable Analog Scaling
Pop-up to change scaling of analog inputs.
Back-up Local Data Needed local data logging in
case connection went down. Wanted to trend non
financial values as well. Password Protection & User
Admin Needed custom password
protection for different screens
Results
1. Far more functionality for a lower cost
2. Less work for OEM when building different skids
3. Better looking HMI
4. Lots of room for expansion to future features
Recap
1. LACT Units are vital for business1. Good Flow Meter2. Smart Controls3. Good Communication
2. Siemens Solution1. S7-1200 is low cost high
feature processor2. Improved capability and
room for expansion
