However, these raw numbers from the PLCâs analog card must be mathematically scaled inside the PLC to represent real-world units of measurement, in this case 0 to 700 GPM of flow. Formulate a scaling equation to program into the PLC so that 4 mA of current registers as 0 GPM, and 20 mA of current registers as 700 GPM. ... Our distinguished colleague and PLC guru Ron Beaufort has posted an excellent thread on scaling. However, OP says that value of Prime2BoothPressure should be 0 at the analog input value of 15396, and the calculation above assumes the 0.00003 scaling factor is correct. The following table summarizes the set and reset conditions for the status bits. For Ex I0.0. I am new at PLC programming. The goal is to mimic the function of a PLC without the actual hardware and thus do advanced debugging. PLC program Explanation:-In network 1, we have done the multiplication of measured value and maximum temperature value and stored the result in MW12.. I wouldn't advise doing it that way if you are doing basic scaling with no filtering because it â¦ Expressing analog values as digital values. FC105 reads the integer value for analog input stored in PIW256 (parameter IN). We have one temperature sensor which is sensing 0â100 degree temperature. The value can be a word or address, and integer constant, floating point data element, or floating point constant. This course is recommended for advanced level programmers who already in-touch first with FX Series PLC'S and GX Works 2 software. LAST EDITED ON Aug-13-01 AT 08:08 AM (EST) In the SLCs, and depending on which analog input card you use, 20 mA is 16384 (2^14), and 0 mA is 0. For example, the scaled output value will not necessarily be clamped between the scaled minimum and scaled maximum values. System scale. For any unit conversion on any PLC, you can use four function math with the following for PLC Analog Input Conversion Formula, which assumes integer math, as follows : DataOffset = Data in input register at 4 mA (or zero analog signal of whatever range â for example 0 VDC on a 0-10 VDC transmitter) The PLC simulation CD that accompanies the text provides hands-on programming experience. An Allen-Bradley SLC500 programmable logic controller (PLC) uses a 16-bit analog-to-digital converter in its model 1746-NI4 analog input card to convert 4-20 mA signals into digital number values ranging from 3277 (at 4 mA) to 16384 (at 20 mA). The other images from post #1 suggest a slightly different scaling factor, i.e. The above calculation method is the general method for scaling, it can be used for any PLC. I need a formula for scaling a number from one linear range to fit in another linear range. )/(input max.

This book is intended to provide a resource to help the user select, install and use thermocouples properly. An analog signal range that has a non-zero low-end, such as 3 to 15 PSIG or 4 to 20 mA, is known as a âlive-zeroârange because the low end is not dead, but has some pressure, voltage, or current present at all times. 2. also is there a way to normalize and scale the analog input that is communicated over a gateway to PLC, instead of physical sensor input. The following formula will convert analog input to data to engineering units: The Input Minimum, Input Maximum, Scaled Minimum, and Scaled Maximum are used to determine the slope and offset values.
