Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
Hello, For my program I need an extended pulse timer, which can be referred to as a retriggerable pulse timer. Where every rising edge of the input resets the elapsed time zero, extending the lenght of the output pulse. The Codesys pulse timer (TP) is a one-shot timer and only resets the elapsed time with the falling edge of the input. There is also a pulse timer (LTP) in codesys, but in my simulation it was also functioning as a one-shot even though the description sounds like LTP should be retriggerable. I have uploaded some timing plots from another PLC program for reference. I am looking for a timer equivalent to the "TEP" diagram. Is there an Extended Pulse Timer in Codesys? Maybe there is a way to manipulate the input so it resets the elapsed time outside the function block?

Hi, how to create a stopwatch when start is pressed, timer will start counting and stop is pressed, timer will stop counting in structured text?

Good morning! Is there a way to run a python script or something else automatically after CODESYS (3.5) did its build or before download? I am searching for something like the Custom Build steps in Visual Studio. Thank you! Voffi

Post by ofey on Testing of Codesys program ^{CODESYS Forge talk (Post)}
Hi! I thought to hear what you guys think is the best way to test the program in my scenario. I have some PLC programs that have been made and deployed on different PLC's. The program has added the specific devices and IO that is applicable. I have made a test environment for everything outside of the PLC, ie. the same SCADA system that is talking to the PLC, and a program running locally is simulating the plant (level regulation of different tanks). Pr. now I have had to manually change the variables that are reading/writing values from the IO so they read/write via OPC instead. I also have to change the device tree from the specific PLC rack, to the soft PLC. So I kind of end up with two different programs that I have to maintain. I was just wondering if you believe there is an easier way to do this. So I can have the exactly same program and kind of switch between the soft mode, and the "real" mode.

I have a simulation function that toggle xSimActive. I map all IO variables to "IO GVLs" when xSimActive=0. I map IO corresponding SimIO GVL to "IO GVLs" when xSimActive=1. Then I write code for the simulation program that runs when xSimActive=1. Typically increase flow corresponding to pump speed, simulate tankfilling corresponding to flow and so on. I made a FC that require a correct code to activate simulation to avoid unintended activation by service dept. When comissioned remove any possibility to activate simulation. Super when officetesting and supporting service dept. + cheap as it requires no additional equipment, and it is easier to support customer later on in the life cycle as you can test proposed changes without setting up a testlab.

Post by simotion on Inheritance of axis ^{CODESYS Forge talk (Post)}
I have developped a function block 'Axis' the inherits from 'AXIS_REF_SM3' -> FUNCTION_BLOCK Axis EXTENDS AXIS_REF_SM3 In my global variable list I define a variable MasterDrive of type Axis and assign Axis1. Axis1 is a virtual drive (AXIS_REF_VIRTUAL_SM3). This type should inherit from AXIS_REF_VIRTUAL. VAR_GLOBAL MasterDrive : Axis := Axis1; However I get the error 'Cannot convert type'. What is the way to obtain what I want : function block inheriting AXIS_REF_SM3 and initialising this function block with a Softmotion virtual or real axis?

Hi, I have been working on Codesys V3.5 with PFC200 controller and Can Gateway 750-658. I want to convert the incoming CAN data from bytes into UINT and for outgoing data bytes to UINT. Does anyone has experience with this kind of data? I tried few different ways but it doesn't seem to be working.

Post by voffi on Converting UINT into bytes and converting 2Bytes into UINT ^{CODESYS Forge talk (Post)}
There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.

Post by open on How to create a stopwatch? ^{CODESYS Forge talk (Post)}
Hi @ph0010421, I tried the program the TimeTaken is calculated when stop is triggered. I want the TimeTaken to be continuously calculated and counting when a BOOL variable is true. I tried to program this way: Declaration: PROGRAM PLC_PRG VAR bStartStop: BOOL := FALSE; // Start/Stop button bReset: BOOL := FALSE; // Reset button bRunning: BOOL := FALSE; // Flag indicating whether the stopwatch is running tStartTime: TIME; // Variable to store the start time tElapsedTime: TIME; // Variable to store the elapsed time END_VAR Implementation: // Main program logic IF bReset THEN // Reset button pressed, reset the stopwatch bRunning := FALSE; tElapsedTime := T#0s; ELSIF bStartStop THEN // Start/Stop button pressed, toggle the running state IF bRunning THEN // Stop the stopwatch bRunning := FALSE; ELSE // Start the stopwatch bRunning := TRUE; tStartTime := tElapsedTime; END_IF; END_IF // Update the elapsed time when the stopwatch is running IF bRunning THEN tElapsedTime := tElapsedTime + T#1s; // Adjust the time increment as needed END_IF However counting of the seconds is not accurate. I tried changing the main task cycle time interval to 1000ms. The counting of seconds become slower. (see attached) Please help
