Hi All, I have hands on rockwell software like rslogix 5000 and studio 5000. Currently started working on codesys i want to know is there any COP instruction with similar functionality in codesys like rockwell. I want to use it to split REAL into 2 INT,DINT to 2 INT also reverse 2 INT into DINT and 2 INT into REAL. Thanks in advance

Hello there, I am new here and in programming. I need help with the basics. I am trying to do what I mentioned in the title. I have an analog input. So I have a real or integer data type value. I want to delay it. TON and TOF only work with bool. I think there is a function block that has two inputs, 1 for real or int and 1 for bool. And if bool is true, it will give the output as real or int. I don't know but I need something like this. Actually, it is not exactly like that. In other words, it will not show the real value at the input at the output after a certain period of time. I want it to show the real value from 2 seconds ago continuously. The purpose of doing this is to compare the real value I received with the value from 2 seconds ago and find out whether it went up or down. I am using only FBD. Please help me with this. Thanks in advance.

Hello otdeveloper, I am very interested in this topic. I have been dedicated to IEC 61499 for some time and I would like to understand if the time has come to adopt it in the real world of automation or if it will continue to fill up research papers only.

Are you able to dynamically change the JSON message? As in, if wsValue or iValue is linked to some real telemetry that varies over time, will the JSON message reflect these changes? I am only able to send the values that I initialize the JSON message to

Maybe try going back to step one and: Var Reg1: WORD; Reg2: WORD; Reg12: DWORD; Value: REAL; end_var // program Reg1:= 4096; Reg2:= 14884; Reg12:= (reg2 * 65536) + reg1; Value:= DWORD_TO_REAL(Reg12);

Recently we had an issue regarding some simple code to calculate a rolling average. The code indexes from zero to 199 to properly store the current input into a circular buffer which then allows us to calculate a rolling average: VAR input_5s : REAL; outs_arr : ARRAY[0..199] OF REAL; i : USINT := 0; END_VAR ___ //this code runs every five seconds, calculating a rolling average outs_arr[i] := input_5s; i := i + 1; output := OSCAT_BASIC.ARRAY_AVG(ADR(outs_arr), SIZEOF(outs_arr)); IF i >= SIZEOF(outs_arr) THEN i := 0; END_IF There is a simple bug in this code where the index will be set to 0 when it has surpassed the length of the array in bytes (800 in this case) rather than larger than the number of reals in the array (200). The solution here is simple, replacing i >= SIZEOF(outs_arr) with i >= SIZEOF(outs_arr)/SIZEOF(outs_arr[0]). In this example when the index increased to 201 and the line outs_arr[201] := input_5s was called, codesys arbitrarily wrote to the address in memory that is where outs_arr[201] would be if the array was that long. I would like to find a way to wrap the codesys array inside of a wrapper class that checks if an input is within the bounds of an array before writing to that value. I know how I would implement that for a specific array, I could create a method or class that takes an input of an array of variable length, ie. ARRAY[*] OF REAL, but I don't know how to make this for any data type. I am wondering if anyone has ever done anything similar to this, or has any better suggestions to ensure that none of the programmers on this application accidentally create code that can arbitrarily write to other locations in memory.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
