HMIs Adapt to Reality on the Plant Floor


The Industrial Internet of Things promises to make factories more productive and agile through connectivity, cloud computing and data analysis. This new era in industry relies on a host of tools and technologies, including sensors, actuators, software, low-power wireless networks and device monitoring.

One area within industrial plants that is adapting to these changing dynamics is the human-machine interface (HMI). At its most fundamental level, the HMI allows machine operators to monitor equipment and respond to changes. In recent years, however, it has evolved into a central system enabling data-driven decision-making in an increasingly mobile environment.

RS-232 Communications


* curated information from The PLC Manual

RS-232 is an asynchronous communications method (a marching band must be “in sync” with each other so that when one steps they all step. They are asynchronous in that they follow the band leader to keep their timing).

We use a binary system to transmit our data in the ASCII format. PLCs serial port is used for transmission/reception of the data, it works by sending/receiving a voltage, With RS232, normally, a 1 bit is represented by a voltage -12 V, and a 0 by a voltage +12 V. (The voltage between +/- 3 volts is considered There are 2 types of RS-232 devices.)

DTE – Data Terminal Equipment and a common example is a computer.

DCE – Data Communications Equipment and a common example is a modem.

PLC may be either a DTE or DCE device.

When plc and external device are both DTE, (or both DCE) devices they can’t talk to each other. The solution is to use a null-modem connection.

Usually, The plc is DTE and the external device is DCE.

Using RS-232 with PLC

Some manufacturers include RS-232 communication capability in the main processor. Some use the “programming port” for this. Others require a special module to “talk RS-232” with an external device.

External device may be an operator interface, an external computer, a motor controller, a robot, a vision system, etc.

To communicate via RS-232 we have to setup:
1. Where, in data memory, will we store the data to be sent?
2. Where, in data memory, will we put the data we receive from the external device?

PLC Communication II


* Curated information from The PLC Manual

START/STOP Bits

start bit. This is a synchronizing bit added just before each character we are sending. This is considered a SPACE or negative voltage or a 0.

stop bit. This bit tells us that the last character was just sent.
This is considered a MARK or positive voltage or a 1.

Parity bit

Parity bit is added to check whether corruption has occurred. Common forms of parity are: None, Even, and Odd. During transmission, the sender calculates the parity bit and sends it. The receiver calculates parity for the character and compares the result to the parity bit received. If the calculated and real parity bits don’t match, an error occurred and we act appropriately.

Baud rate

it is the number of bits per second that are being transmitted or received. Common values (speeds) are 1200, 2400, 4800, 9600, 19200, and 38400.

RS232 data format

RS232 data format (baud rate-data bitsparity-stop bits). 9600-8-N-1 means a baud rate of 9600, 8 data bits, parity of None, and 1 stop bit.

Software handshaking

Software handshaking (flow control) is used to make sure both devices are ready to send/receive data. The most popular “character flow control” is called XON/XOFF. The receiver sends the XOFF character when it wants the transmitter to pause sending data. When it’s ready to receive data again, it sends the transmitter the XON character.

STX & ETX

Sometimes an STX and ETX pair is used for transmission/reception as well. STX is “start of text” and ETX is “end of text”. The STX is sent before the data and tells the external device that data is coming. After all the data has been sent, an ETX character is sent.

ACK / NAK Pair

The transmitter sends its data. If the receiver gets it without error, it sends back an ACK character. If there was an error, the receiver sends back a NAK character and the transmitter resends the data.

PLC Communications


* curated information from The PLC Manual

PLC Communications

Extension modules

PLC I/O number can be increased through certain additional modules by system extension through extension lines. Each module can contain extension both of input and output lines.
Extension modules can have inputs and outputs of a different nature from those on the PLC controller. When there are many I/O located considerable distances away from the PLC an economic solution is to use I/O modules and use cables to connect these, over the long distances, to the PLC.

Remote I/O connections
When there are many I/O located considerable distances away from the PLC an economic solution is to use I/O modules and use cables to connect these, over the long distances, to the PLC.

Remote PLCs
In some situations a number of PLCs may be linked together with a master PLC unit sending and receiving I/O data from the other units.

Cables
Twisted-pair cabling, often routed through steel conduit. Coaxial cable enables higher data rates to be transmitted and does not require the shielding of steel conduit.

Fiber-optic cabling has the advantage of resistance to noise, small size and flexibility.

Parallel communication
Parallel communication is when all the constituent bits of a word are simultaneously transmitted along parallel cables. This allows data to be transmitted over short distances at high speeds. Might be used when connecting laboratory instruments to the system.

Parallel standards
The standard interface most commonly used for parallel communication is IEEE-488, and now termed as General Purpose Instrument Bus (GPIB).
Parallel data communications can take place between listeners , talkers , and controllers. There are 24 lines: 8 data (bidirectional), 5 status & control, 3 handshaking, and 8 ground lines.

Serial communication
Serial communication is when data is transmitted one bit at a time. A data word has to be separated into its constituent bits for transmission and then reassembled into the word when received. Serial communication is used for transmitting data over long distances. Might be used for the connection between a computer and a PLC.

Serial standards
RS-232 communications is the most popular method of plc to external device communications. RS 232 is a communication interface included under SCADA applications. Other standards such as RS422 and RS423 are similar to RS232 although they permit higher transmission rates and longer cable distances.

 There are 2 types of RS-232 devices:
DTE – Data Terminal Equipment and a common example is a computer.
DCE – Data Communications Equipment and a common example is a modem.
 PLC may be either a DTE or DCE device.

ASCII
ASCII is a human-readable to computer-readable translation code
(each letter/number is translated to 1’s and 0’s). It’s a 7-bit code, so we can translate 128 characters (2^7 is 128).

Protocols
It is necessary to exercise control of the flow of data between two devices so what constitutes the message, and how the communication is to be initiated and terminated, is defined. This is termed the protocol.
One device needs to indicate to the other to start or stop sending data.
Interconnecting several devices can present problems because of compatibility problems.
In order to facilitate communications between different devices the International Standard Organization (ISO) in 1979 devised a model to be used for standardization for Open System Interconnection (OSI).

PLC Operation


* curated information from The PLC Manual

PLC Operation

Input Relays
These are connected to the outside world. They physically exist and receive signals from switches, sensors, etc. Typically they are not relays but rather they are transistors.

Internal Utility Relays
These do not receive signals from the outside world nor do they physically exist. They are simulated relays and are what enables a PLC to eliminate external relays.

There are also some special relays that are dedicated to performing only one task.

Counters
These do not physically exist. They are simulated counters and they can be programmed to count pulses.

Typically these counters can count up, down or both up and down. Since they are simulated they are limited in their counting speed.

Some manufacturers also include highspeed counters that are hardware based.

Timers
These also do not physically exist. They come in many varieties and increments.

The most common type is an on-delay type.

Others include off-delay and both retentive and non-retentive types. Increments vary from 1ms through 1s.

Output Relays
These are connected to the outside world. They physically exist and send on/off signals to solenoids, lights, etc.

They can be transistors, relays, or triacs depending upon the model chosen.

Data Storage
Typically there are registers assigned to simply store data. Usually used as temporary storage for math or data manipulation.

They can also typically be used to store data when power is removed from the PLC.

Artificial Intelligence Is Hot – Where Art Thou Heading AI? – Part 1


* Curated Information

Articial Intelligence (AI) can be defined as “an area of computer science that deals with giving machines the ability to seem like they have human intelligence” or “the theory and development of computer systems able to perform tasks that normally require human intelligence, which includes cognitive tasks such as planning, reasoning, and learning, and perceptual tasks such as recognizing speech, understanding text, and recognizing faces”. Some people prefer to use cognitive intelligence (maybe a somewhat more marketing-oriented term) instead of AI, some may use the term robotics, and some substitute machine intelligence or machine learning interchangeably with AI. 

However, cognitive technologies and machine learning are sub-fields of AI. All machine learning is AI, but not all AI is about machine learning. Similarly, deep learning, a subset of machine learning, is all about machine learning, but not all machine learning is deep learning.
