Post by lgeertsema on Checkbox font color in visualization style ^{CODESYS Forge talk (Post)}
Hello, I'm having a similar issue with buttons. I want to be able to set the default color and transparency of a button. I've tried a lot of different iterations like KNewman, but to no avail. Has there been some documentation released since KNewman posted this, or is the style editor still as undocumented as ever?

Post by kimnegw on Codesys offline license batch ^{CODESYS Forge talk (Post)}
Hey guys, I'm currently developing a Codesys application for an offline Linux device. I can easily set up the license for ONE device using my Windows PC, but what happens if I need to produce a thousand devices? Is there any method to automate license insertion? I have already generated a dpkg installer for deploying the Linux control application to multiple targets. Thanks,

Post by riccardo on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
GoodMorning everyone. I have a system that, in case of alarm, have to block. When the operator logs in must have to acknoledge the alarm and should operate in the system freely. To perform this I detect the logged User by (VisuElems.CurrentUserGroupID <> 0) with a similar code to the the following: PROGRAM AlarmMngt VAR alarm : BOOL:= FALSE; Ack : BOOL:= TRUE; PushBottonOpening : BOOL:= FALSE; Valve : BOOL := FALSE; Flag: BOOL := FALSE; END_VAR IF alarm AND Ack AND (NOT Flag) THEN valve := FALSE; PushBottonOpening := FALSE; Ack := FALSE flag := TRUE; ELSIF (NOT alarm) AND Ack THEN flag := FALSE; END_IF (* if the system is in alarm but there is a logged operator that acknowledge the alarm the system allows the valve opening.*) IF (VisuElems.CurrentUserGroupID <> 0) AND Ack AND Alarm AND PushBottonOpening THEN Valve := TRUE; ELSIF (VisuElems.CurrentUserGroupID = 0) AND Alarm THEN valve := FALSE; END_IF The problem I have is in the last 5 lines of the code: Even if there is a logged in user, the GroupID variable is subjected to a refresh that cyclically set for an instant it to 0 and this close the valve making difficult to the user to work Now I solved it creating a time hysteresys cycle but it is not a good solution. Someone is able to explane me why the GroupID variable is sobjected to this refresh and how to stabilize to avoiding it? Thank you in advance, Riccardo

Post by bertus on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hi Georg, thanks for your time. What is the value of D_ANGLE_TOL? It is set to 0.01. Do you need the assignment bAbort := NOT bDecoder? Does it help to leave it out? This seems to make no difference. Any errors (e.g. SMC_SmoothPath.Error/ErrorID) or PLC log messages? No errors or log messages. What if you comment out SMC_SmoothMerge and SMC_LimtiDynamics, is corner smoothing still not working? Indeed. Is bDecode written from a different task (e.g. visu)? Then I would recommend to assign to a local variable (bDecodeLocal := bDecode) and use that for all FBs. Otherwise, FBs might see different values of bDecode in a single cycle, which will cause problems. It is a local variable, written from a state machine inside this program. But there is new information: During some trial and error, I tried skipping "stage 2: merge short linear segments" (SMC_SmoothMerge). And suddenly it rounds the corners, see attached image. Looking a bit closer, I noticed that (with the original program) after a download (cold start?), it in fact did round the corners, but only once. Ever next cycle in which the NC program was executed, the corners where not rounded. Not sure if there is any relation, but SMC_SmoothMerge is also the only FB which has no bAbort input. Perhaps I need to reset it (or any buffers) by other means?

Post by konstantin on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Hello, one of the projects I work on is about a racetrack collator with two independent belts on it - two different servo motors. Both motors share the same mechanical frame and there is a train on a belt that collects items from the input conveyor. The way the motion is performed is the following - there is a virutal master axis and both real axis are synchronised with different cam motion profiles. The problem is when an STO is triggered on any of the slave axis, the synchronization process starts from position 0 of the slaves. How can I force the slaves to retain their current position until the master passes their position? Then the slaves should catch up with the master according to the profile, the slaves should not start synchronization from 0 position. Best Regards Konstantin Kolev

Post by alex-n on Problem with keeping up the distance between two axes ^{CODESYS Forge talk (Post)}
Hello. I have a task to synchronize the movement of two axes and maintain the distance between them. First axe makes equal steps by trigger using MC_MoveRelative function. The second one is standstill and after another signal should catch up the first one from its position to a specified distance and keep it. I've tried to use MC_Phasing and mostly it works. Second axis catches up the first and starts make step with it. But in one moment this axis can crash into the first and there is no clear connection as to why this is happening. It can work correct for a day or for a week.

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
How are the servo drives controlled? EtherCAT, step/dir pulses, other? CANOpen, 1 Mb/s, bus load 35%, cycle time 2ms. Another thought is that - if it's step/dir pulse based control - the pulses from the PLC to the drive are getting missed/lost at high frequencies? If that's the case then there would be multiple troubleshooting steps/corrections that could be investigated. Here, it seems to me that we are getting completely off track with the observed problem. You could try to create a simplified program I had already written this elsewhere. The program before being brought into machines was exhaustively tested in SW emulation and the problem did not occur. However, in emulation I was interested in checking other aspects of the process, not this specific one which is for real a correction made necessary after the fact. The part of the program that does this correction with the function mentioned in the topic, came up from its origins, but I didn't know or didn't think it was really useful. A scruple that later turned out to be necessary. However, for now I do not think I will spend any more time on this verification, already lacking any to do my normal. I remain amazed, however, that a function intended to correct the axis position with the motor in motion and that it should not interfere with this, in fact instead changes behavior as the motor speed changes. Mah! When you manually control the motor directly from the servo drive software at the speeds you are calling for, does it move precisely to the target position? The drive and motor have been working fine for about 10 years. In replacing the machine control system, I opted for CoDeSys where before there was something else. But this is not the subject of the problem. What I need to resolve is the fact that a clutch specially placed at a certain point can slip and, therefore, I have the undeniable need to phase the 'prime mover' to the mechanical position of the machine, detected by a cam for each turn, in order to properly stop at its optimum point. Which for now I have ruled out doing. In fact, if I really have to say, since we have now gone brutally OT, I originally thought that this clutch should only come into action in cases of extreme necessity, as happens in most trials. But this one, the way it is made, slips more easily than I could estimate and the servo-controlled 'prime mover,' and the machine, get out of phase, maybe by a little, but frequently, and when the machine work at it's high speed, (in fact all of the time), I can't adjust properly the 'prime mover' position at fly.
