SUPPORT SOLUTIONS

Filtering of Noisy Process Variables
by Luis Miranda, ADC Tech Support team member

The problem of noisy signals in the measurement of process variables can typically be solved with careful design, taking into account components, layout, wiring, grounding, shielding, etc. However, no matter which layout you select, electrical noise may still be present in the input signal of a PLC.

In the most severe cases, it is necessary to resort to signal filtering, either by hardware or software, to smooth the reading. The value of the process variable can also be unstable due to the quality of the measuring instrument. For example, in the cement industry, the signal output generated by impact flowmeters of granulated or dusty raw materials results in a value that must be averaged. Even the value of the gasoline level in an automobile tank needs to have an algorithm that calculates the average of several readings, to prevent the needle of the indicator from jumping when the automobile moves.

Running average is one of the methods used to smooth readings of analog values. In this algorithm, the parameters are the number of samples and the sampling period of the signal. This method consists of taking a consecutive number of readings, not necessarily at the same frequency of the CPU scan, and placing them in a table. In each sampling, the new value is placed at the top of the table, all the other values will move downwards, and the oldest value is lost. At the same time, all the values of the table are added and the arithmetic average of those values becomes the running average. Then, in each reading, there is a value that is the average of all the samples. If it is known that the process variable varies slowly, as is the case with temperatures or water level in a tank, this method can be easily applied.

A solution for AutomationDirect's DirectLOGIC PLCs is as follows:

In this example diagram (diagram will open in a web browser window), assume that there is a range of temperature with a noise signal that can cause the value of the signal to jump instantaneously, which can then cause a non-acceptable deviation or enough change to activate an alarm. We want to smooth the reading of a 12 bit analogic signal read by a PLC with a scan time of 9 milliseconds, (i.e., on each 9 msec there is an update of the reading). In the example, we will take a value each 11 CPU scans.

The table to use is V10000, with 10 consecutive registers, or a table of a length 10 (V10000 until V10011). The signal value to be averaged is V4000. The result is obtained in V5000 as a BCD value.

Next you can see an implementation of the algorithm with a period of sampling of 100 milliseconds and 10 samples. This can be extended to more samples, and the period can be changed within the possibilities of the CPU. Furthermore, the averaging and sampling in each CPU scan can be done by slightly modifying the program.

TECH TALK

Application of the month: DL205 and EZTouch increases productivity for coil form manufacturer

Products used: DL205 and 6" EZTouch

Description: Cosmo Corporation produces coil forms for the electrical and electronic industries. This includes thermoplastic and thermoset molding as well as round wire, square wire, flat terminals, and assemblies. My challenge was to improve the assembly operations. By implementing systems using the DL205 and EZTouch panels, I was able to build user-friendly controls which include automatic and manual operation, but more importantly, complete diagnostics and data collection at the touch of a button. The new controls and diagnostics reduced maintenance requirements to the barest minimum, and the data collection provides production with accurate, real-time operator, part number, and machine capability information. This being a newly implemented project, the full impact of the improvements is yet to be appreciated, however I can say that the reduction in maintenance, increased reliability, and improved performance has improved productivity by nearly 14%, and the production data provides information for accurate/competitive pricing of our products.

In each of the sentences below, the names of two countries are hidden. For example, the sentence: "Interpol and the FBI track down hidden marksmen" conceals the names POLAND and DENMARK.See if you can find all twenty hidden countries:

1. Vladimir and Olga are Soviet names.
2. Have you ever heard an animal talk in dialect?
3. The children put on galoshes to go out in the rain.
4. Extra tuition will help an amateur to improve his painting.
5. In the United Nations we denounce the wholesale ban on atomic weapons.
6. Rash decisions may lead to trouble so thorough analysis is required.
7. The prince has not found a home yet since leaving his fine palace.
8. Such a display could be either really grand or rather disappointing.
9. Give the dog a bone and give him a little water.
10. If an iron pipe rusts you just have to shrug and accept it.
