Post by manuknecht on Maximum dynamic limits of MC_MoveLinearAbsolute and MC_MoveLinearRelative ^{CODESYS Forge talk (Post)}
Hello all I use an axis group with two linear axes in a kinematic system. Using MC_MoveLinearAbsolute and MC_MoveLinearRelative, I am trying to realise dynamic movements (set velocity: 1 m/s, set acceleration: 30 m/s^2) with the highest possible jerk, as I want to compare this with a movement with a trapezoidal velocity profile. However, my measurements show that the axes accelerate with a maximum jerk of approx. 800 m/s^3, even if the value in the function block was set to 10,000 m/s^3. I have already increased the dynamic limits of the two axes accordingly (Velocity: 5000 u/s, Acc-/Deceleration: 250'000 u/s^2, Jerk: 100'000'000 u/s^3, where 1 u = 1 mm), but this had no effect. I have checked the input parameters of the function blocks and the VelFactor, AccFactor and JerkFactor factors are all set to the maximum (value 1). Reducing the cycle time has resulted in a higher jerk, but as we are already working with a cycle time of 1 ms, there is nothing more that can be done here. The axes themselves are still a long way from drawing the maximum current, which is why I assume that this should not be a problem either. Are there other factors or parameters that influence the dynamic limits and therefore allow faster movements? The PLC I am using is a Raspberry Pi 4 and Codesys V3.5 SP20 with all libraries up to date. Thanks in advance Manuel

no nowadays I would recommend connect by name. Which is the default I guess since some versions.

DO NOT use the same username and password in Codesys as your default Rpi OS admin user on the Pi.

P.S.: I'd prefer a lighter color because the default blue makes it difficult to tell a normal contact vs. negated, etc.

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
