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 (Internet 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.

Valentine’s Day celebrates romance, love and affection between couples and hope to be couples. Customarily the exchange of flowers, chocolates and other gifts occurs on February 14th each year.
How and Why did this custom develop?
The Roman Fertility Festival Lupercalia was celebrated in mid-February each year. Emperor Claudius II banned young men from marrying sometime before 270 A.D believing that single men made better soldiers. Young love would not be stopped and a sympathetic temple priest named Valentine would secretly marry young couples. When this was found out, Claudius II had Valentine publicly beheaded in 270 A.D. In 496 A.D. Pope Gelasius I proclaimed Valentine a Saint and declared February 14th as Saint Valentine’s Day replacing the Pagan Lupercalia Festival. Valentine is the Patron Saint of affianced couples, bee keepers, engaged couples, lovers and happy marriages.
Much much later, the exchanging of cards and chocolates on this day became popular in England and spread to North America where commercial drivers to sell cards, chocolates and flowers proved an economic bonanza that spread worldwide.
Think of and enjoy your loved ones today! Happy Valentine’s Day!
March 13th is one of three Friday the 13ths in 2015. March and November will offer two additional Friday the 13ths . While each year has at least one Friday the 13th, it will be 2026 before another year presents three Friday the 13ths.
The superstitious believe that Friday the 13th brings bad luck. Some believe that this originates from the date that the Knights Templar were arrested and their assets seized under the orders of French King Phillip IV on Friday the 13th, 1307. The Knights Templar name was derived from their first headquarters established in Jerusalem as Temple of Solomon in 1120 in the captured Al Aqsa Mosque on the Temple Mount which was allegedly built upon the ruins of Solomon’s original temple.
The Knights Templar were formed to protect Christian Pilgrims on their journey to Jerusalem and started with nine knights including Godfrey de Saint-Omer and André de Montbard. Their emblem of two Knights riding a single horse represented their poverty compared to other rival Knightly Orders such as Hospitaller and Teutonic . They lived on donations from Christian nobleman and Kings and were granted special privileges by the Church. Quickly their Order grew in size and assets. The likely high point of their military crusades was the defeat of Saladin’s army of 26,000 at the Battle of Montgisard with a few thousand soldiers led by 500 Templar Knights with their fierce attacks in full armor mounted on horses in 1177.
Over the years, the Knight Templars influence grew far away from the battlefield with administration, castles and estates in France and England. They developed one of the first banking systems so that travelers could make a deposit at the local Templar and receive a coded letter that when delivered to another Templar site allowed them to receive funds less a donation. This allowed travelers to avoid being robbed of gold or other riches by bandits when traveling.
As leadership changed, so did the Knights fortune. The Knights Templar rode across a desert in full armor with no rest to reach the Battle of the Horns of Hattin in 1187 where they were defeated soundly by Saladin when Muslim forces recaptured Jerusalem. Their military influence waned to non-existent as their financial position rapidly grew. While the Knights took an oath of poverty, the wealth the Order controlled was vast.
King Phillip the IV persuaded the new Pope Clement who had moved the Catholic Curia to Avignon France and under Phillip’s influence to investigate alleged crimes of the order so as to avoid paying the huge debt he owed the Knights Templar from financing his war with England. The Knights were accused of Satanic and Pagan like rituals and Heresy.
And so, on the morning of Friday the 13th, 1307 began the destruction of the order with the arrests and torture of the Knights culminating with Grand Master Jaques de Molay and Geoffroi de Charney, Preceptor of Normandy, being burnt at the stake in Paris on March 18, 1314 after recanting their earlier confessions. Jaques de Molay allegedly screamed through the flames that “God knows who is wrong and has sinned and a calamity will occur to those who condemned us to death”. Pope Clement died within a month and King Phillip died of a hunting accident within a year.
The Great Fortune of the Knights Templar was never found and legends abound with most featuring escapes with Treasure by the surviving Knights to England, Scotland, and North America.
Congratulations to the New England Patriots and MVP Tom Brady on their Super Bowl Victory over the Seattle Seahawks!
What about Snow Gate?
PSC is closed today after being hit by another Winter Snow Storm in Boston. In a developing story called Snow Gate, it has been reported that Process Sensors is closed today based on snow and road conditions. The closing may be “covering” for all the New England Patriots fans recovering from too much chile and chowder celebrating the most widely viewed Super Bowl of all time, decided in the last few minutes. Story developing …
GLENDALE, Ariz. (AP) — Ten years removed from his last Super Bowl win, Tom Brady wasn’t letting this one slip away.
Sure, the brilliant Brady needed a huge play by an undrafted rookie to preserve New England’s 28-24 Super Bowl victory over Seattle on Sunday night. But Brady’s imprint was all over the Patriots’ sensational fourth-quarter rally for their fourth NFL championship of the Brady-Bill Belichick era.
“You know, whatever it takes,” the record-setting Brady said after throwing for four touchdowns, including a 3-yarder to Julian Edelman with 2:02 remaining as New England rallied from a 10-point deficit. “Every team has a journey and a lot of people lost faith in us … but we held strong, we held together, and it’s a great feeling.”
Parts of Connecticut, Maine, Massachusetts, New Hampshire, New York and Rhode Island have seen more than a foot of snow.
Snow amounts in New York have ranged from 7.8 inches at Central Park in New York City to more than 28 inches in eastern Long Island. La Guardia airport in New York City has seen 11 inches.
In Massachusetts, up to 26.2 inches of snow has been measured in Shrewsbury, while Boston endured heavy snow and wind gusts over 30 mph from 1 a.m. to 9 a.m. ET. Wind gusts in eastern Massachusetts have topped 70 mph and coastal flooding has closed some roads.
Thunder snow was reported in coastal portions of Rhode Island and Massachusetts late Monday night and early Tuesday.
