SNACKEX 2015 closed its doors on 11 June after a record attendance of over 2,600 snack industry professionals from 83 countries.
SNACKEX is organised by the European Snacks Association (ESA) and is the only savoury snack and snack nuts event in Europe serving as the pre-eminent business meeting place for the whole industy.
The recent Pressure Sensitive Tape Council meeting in Baltimore allowed us an opportunity to present a paper on Near Infrared and Infrared measurement solutions in the PSA market. Dow supplied a new PSA Calculator that may be of value. Click Here for Dow PSA Calculator.

Software communication options can sometimes be confusing and complex when first encountered. Listed below is a glossary of common acronyms, what they represent and a brief outline of our PSC Viewer Suite Software and Guardian Communications. Please visit our Process Sensors Website for more information.
Ethernet: Physical method of cabling that connects devices on the Ethernet network. Basically, there are two types of Ethernet, Local Area Network (LAN) and Wide Area Network (WAN). LAN example might be computers in an office connecting to a central server. WAN example might be doing your banking over the internet. Our transmitters and Guardian Systems communicate on a Local Area Network.
IP (Industrial Protocol): The Internet Protocol is the most basic protocol. It simply moves a packet directly from one Ethernet device to another Ethernet device. Almost everything moves across the internet using IP.
TCP (Transport Control Protocol): TCP is a protocol that creates a connection between two nodes over Ethernet. TCP maintains a connection and uses acknowledged messaging to transfer messages between two devices. That means that all TCP messages generate a reply. If there’s no reply, there’s an error.
OPC: For old timers, OPC is OLE for Process Control. OLE is Object Linking and Embedding. These are Industry Standards for communication platforms so that end users and suppliers agree to exchange data in a specific format. Now OPC is Open Platform Communications. It is a Client / Server technology. One application acts as the server providing data and another application acts as the client using the data. OPC is a widely accepted industrial communication standard that enables the exchange of data between multi-vendor devices and control applications without any proprietary restrictions. OPC has also grown beyond its original OLE implementation to include other data transportation technologies including XML, Microsoft’s .NetFramework, and even the OPC Foundation’s binary-encoded TCP format.
Kepware is the communication platform we have selected for OPC communications. End user needs to purchase a copy of Kepware Runtime and download for some nominal fee like $100 for the system that is communicating with the Guardian (or transmitter). This is only required when customer requests OPC communication.
DDE (Dynamic Data Exchange): DDE is a method for exchanging information between applications running on Windows. A simple example is exchanging data between Word and Excel. All you really need to know is that it is a Windows based method to exchange data between applications. It’s been working since Windows 2.0!
CIP (Common Industrial Protocol): CIP is the basic component that forms the basis of EtherNet/IP. There are two parts to CIP, an Object/Attribute Library and a Messaging structure. CIP devices use a very specific data model based on Objects (related collections of data) and Attributes (Data Identifiers). CIP devices have a very specific set of messages that they support. There are Explicit Messages and Implicit Messages. Explicit messages are sporadic, one-time messages requesting data values or setting parameters. Implicit messages are ongoing I/O messages that are exchanged between two CIP devices.
EtherNet/IP is a very complex protocol but you can break it down into this; the Scanner (usually a PLC) exchanges data buffers with each Adapter. The Scanner sends Outputs to each Adapter device. Each Adapter device sends some Inputs back to the Scanner. This is not our physical across the web scanner, it is the PC scanning the network. The Adapter is our transmitter or Guardian.
Modbus is a serial communications protocol that allows multiple devices to be attached to the same network. An example might be connecting a moisture transmitter and separate temperature transmitter to the same network.
SCADA (Supervisory Control and Data Acquisition) is a system operating with coded signals over communication channels so as to provide control of remote equipment (using typically one communication channel per remote station). The control system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions
RS-485 is a Recommended Standard for local networks and multi-drop communications link that transmits data at 35Mbit/s at 10 meters and 100 kbits/s at 1200 meters.
HMI is a Human Machine Interface such as a PLC or a PC equipped with Wonderware or such.
Both EtherNet/IP and Modbus/TCP are Ethernet Application Layer protocols that use the TCP and IP protocols of the TCP/IP stack. They are both highly structured ways of moving data between automation devices in an industrial application. The difference is in how data is represented to the network. EtherNet/IP represents data using the CIP object structure. Modbus TCP represents data as a series of registers (16-bit unsigned values).
Guardian System Communication as an Example
Our NIR (Near Infrared) Transmitter communicates to the Scanner Controller Board via RS-485 Modbus Protocol. This is also how our transmitter communicates with the Operator Interface (OI). The Scanner Control Board communicates with the Guardian PC via Ethernet link using a Windows based Stand-Alone-System.
PSC Viewer Suite Software for the Guardian meets the needs of our customers. Customers can get data on scan and zone averages for archiving. Viewer Suite is not limited to just Ethernet. It can use USB and serial links (RS232 and RS485 multi-drop) as well.
Viewer Suite Software is not limited to scanning frames. It can be connected to multiple sensors and scanning frames at the same time. PSC Viewer Suite Software is smart. If it’s connected to a transmitter only, it presents transmitter software. If it’s connected to one or more scanners it automatically detects that and pulls up Guardian Viewer Suite Software. It can also recognize when it is connected to a mix of scanners and static transmitters.
The Viewer Suite Software saves Zone /Average data to Excel, CSV, XML and to its built-in supplied industry standard SQLite database which is used for simple roll reports. When an HMI is controlling the Guardian or advanced options are required OPC/Kepware and Modbus/TCP are available.
Jenna Marcello is a Junior at Emmanuel College in Boston who participates and sits on the Executive Board of Dance Marathon, the #1 Local Non-Profit Organization that raises money for Children’s Hospital. Jenna is pictured here with Boston Mayor Marty Walsh! Already politically connected Jenna!
The dance marathon a few weeks ago raised over $89,000. 400 Students from 10 p.m. to 10 a.m. danced their heart and lungs out. Think Back to the Future! What a great time all participants had and Jenna helped lead. Congratulations from all of us at PSC who work with her Proud Mother and Father Tony and Berni Marcello! Great Job Jenna!
From All of Us at PSC! Congratulations Jenna!
Left this on my Daughter Darby’s Wind Shield for April Fool’s Day with expected results!
Knowing she could be guilty and seeing college logo caused hesitation, with my straight faced denial, confusion set it.
Then super hugs and laughter over an April Fool’s Day Prank that worked like a Life Time Movie!
