In this video, we are going to be talking about analog inputs to the PLC.
What do we mean by analog input? Analog values are continuous values, such as temperatures and pressures.
While we tend to think of them in digital terms, at some point we have to convert them from the continuous world into our digital world, and this is where analog inputs come in.
Voltage signals in the range of plus or minus 20 volts or so and current signals in milliamps are commonly used as both analog inputs to PLCs.
Every PLC manufacturer has I/O modules to deal with these kinds of signals, along with other, more specialized modules.

I would add that some of the most important reasons why 4-20mA is used over 1-5V: 1. The voltage reading could be inaccurate due to cable resistance voltage drop. 2. The current read in the transmitter and the PLC are identical, for any value of cable resistance, thus the transmitter can sense if the current is not the correct value it intended to transmit so it can adjust its impedance in line to bring back the current to the correct value. 3. Two wire transmitter connects are possible with current but not with Voltage. 4. Under ange (lower the 4mA), over range (higher than 20mA), and wire break (under 3.2mA) can interpreted by the PLC. 5. Current circuit is a very low impedance (normally less than 750 Ohms) so less sensitive to electrical interference compared to Voltage signals. 6. Current circuits allow an easy connection of an indicator in the current loop as long as the total resistance in the loop does not exceed typically 750 Ohms.

Howdy. Nice as usual. Some discussion about measurement precision might be in order. Let's take two pressure transmitters from the same manufacturer. One is 0 - 1 bar and the other 0 - 10 bar. Both have a precision of 0,5 %. What does this mean ? For the first one ( 0,5 / 100 ) x 1 bar = 5 millibar. For the latter ( 0,5 / 100 ) x 10 bar = 50 millibar. The accuracy bandwidth for the first is + - 5 millibar over the whole measuring span and for the latter + - 50 millibar over the whole measuring span. What is the accuracy bandwidth ? It is the + - standard deviation which, somewhat simplified, means that 2 measurements of 3 are inside the bandwidth. Alright. Now the plant manager says he wants to reduce the stock of spare parts and orders the 1 bar type to be removed from the stock replenishing program. Just use the 10 bar type and multiply the reading by 10 in the PLC. What is wrong with this approach ? Let's say we have a reading of 0,8 bar. With the original transmitter the actual value can be 805 millibar but with the replacement as much as 850 millibar. This much a deviation could ruin a production batch. Regards.

Hi, Usually industrial analog sensors are multipoint calibrated to accommodate hysteresis. How can we enter those values in a Siemens Scale-X Norm-X instruction?
@realpars
@realpars 4 жыл бұрын
No. The NORM_X and SCALE_X functions are linear functions and assume only two "calibration" values: 0% and 100%. You could break up your curve into multiple linear segments, one segment between every two calibration values. Then use the NORM_X function to calculate a % of range and use the appropriate "segment's" SCALE_X function to determine your transmitter value.

@realpars
@realpars 2 жыл бұрын
The I/O capacity of any PLC system is limited by its memory reserved for I/O and the number of physical I/O cards that can b addressed. For example, a Siemens S7-1214c can have 51 analog points; an S7-1500 typically has 32x the I/O table memory of an S7-1200, so theoretically, it could have up to 1600 analog points. So you need to determine the number of I/O your system can handle. Even within the Siemens product line, there is a very wide range of capability.

Dear Real Pars Team, I have few doubts, 1) What is meant by "Conditioned Input"? 2) What is the math behind for choosing 500 ohms in the PLC AI Circuit? I mean how we derived the load resistance as 500 ohms kindly explain it in detail with calculations? Thanks in advance Best Regards, PC Raju.
@realpars
@realpars 3 жыл бұрын
Great questions! Conditioned input indicates that the input signal is converted from the native signal from the sensor, 4 - 20ma for example, to a signal that can be used by the electronics in the I/O card, which most often operates on a 1 - 5 VDC signal. For the loop resistance, this depends on the specific analog input card, and as indicated in the video, this resistance is limited to 500 ohms. That does not mean that it is 500 ohms ion every case. For a 4 - 20ma sensor, a 250 ohm resistor is typically used. From Ohms law, V = I * R, so at 4 ma, V = 0.004A * 250 ohm = 1 VDC. At 20ma, V = 0.020 * 250 = 5 VDC.

Knowing that the output signal 4-20mA is, what will happen if the temperature drops below 40°C or rises above 140°C? Will the transmitter send a signal or not? If yes his is this signal calculated? Thanks

Hi Bärenstark, Unfortunately, dropping below or rising above calibrated range has minimal effect on output. You may find d the current values slightly below 4 ma or slightly higher than 20 ma, but nothing significant. You will notice a big change if the current loop is broken. Hope this helps!

Typical loops in a PLC or DCS are powered by 24VDC. Analog loops have a 250 ohm resistor inline, which converts the 24VDC signal to a 1-5 VDC signal that is "native" to the electronics in analog input cards.

When there is a seperate 24v dc supply, why does the negative connection from transmitter goes to the positive connection at analog digital converter and not negative?
@realpars
@realpars 2 жыл бұрын
In a 24VDC current loop (a series loop), you flow from more positive to less positive as you go from one device to another. From the power supply, you connect the (+) terminal to the most positive free terminal (+) of the transmitter. That just leaves the transmitter's (-) terminal, which is routed to the most positive free terminal on the converter (+). Then the remaining terminal, the (-) terminal on the converter goes to the remaining terminal (-) on the power supply. That is how a 24VDC series loop is connected.

As i understand 4-20 mA is converted to voltage (1-5 volt) through 250 ohm or 500 ohm, .. Am I right? My inquire is why the card read voltage (1-5) instead of (4-20 ma)????
@realpars
@realpars 4 жыл бұрын
Great question! Per Ohm's Law for DC circuits, V = I x R. So for a 250 Ohm resistor, 4ma will give a value of V = 0.04A x 250 Ohm = 1 V. For 20ma --> V=5V. The internal circuitry of an electronics board is comprised of many components, mostly comprised of transistor-based devices, like op-amps and IC's. These devices operate in the range of 1 - 5 VDC, so use of a precision 250-Ohm resistor is convenient and inexpensive.

@realpars

Analog inputs are typically configured at the I/O board level (hardware configuration). For Siemens analog cards, the analog inputs are scaled from 0 to 27648 counts (h6C00). The analog input can then be scaled with FC100 (Scale2Real) in STEP7 or by using the SCALE function in TIA Portal.

@realpars

Not quite. Both analog and digital signals pass current through a wire, tyipically at 24VDC. The difference is this: an analog signal is comprised of a current signal that varies in current (milliamps) between 0% signal and 100% signal. The value of a digital signal (probably best called a discrete signal) is either ON (24VDC) or OFF (0VDC).

You will need to add a Logo AM2 module to your basic module. The Logo AM2 module supports 2 analog inputs. When connecting to the module, use 24VDC power and select 24VDC on the module (slide switch). For a 4-20ma sensor, for channel 1, connect (+) to I1 with the corresponding (-) wire connected to M1. Connect the shield to X11. For channel 2, connect to I2/M2/X11.

Real pars, I have a doubt. Why plc generally has less analogue input modules(compared to digital)?
@realpars
@realpars 9 ай бұрын
Hi there, Thank you for your question. Analog input/output channels consume a greater amount of memory compared to digital channels. The memory requirements for your PLC will largely depend on your specific needs, and it's worth noting that using analog channels can be more resource-intensive and potentially costly. To put it into perspective, a single PLC analog channel typically occupies 16 bits of memory, whereas a digital input/output channel only uses one bit out of those 16. This means that you can have a greater number of digital I/O channels to work with in comparison to analog channels. Happy learning!

Why is it called an analog input if the input signal is 4-20 mA DC?
@realpars
@realpars Жыл бұрын
The definition of analog is: "relating to or using signals or information represented by a continuously variable physical quantity such as spatial position, voltage, etc.". In this context, an analog input is continuously variable signal between 4 - 20ma. This signal as transmitted, is typically decoded as a 14-bit or 16-bit signal, which allows the current to be decoded to 16384 discrete increments. For a 16-bit analog card, 1 part in 65536.

@@realpars Thank you for your response. What I don’t understand is if the signal is analog that makes it by definition not digital right? So why do I measure 4-20 mA on the DC setting on a device that is called “analog input”? Perhaps “analog current” does not mean the same thing as “alternating current”?
