Your connection configuration should look something like the attachment. Consuming assembly O->T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producing assembly (T->O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)

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

Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any βcurrent dataβ. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by mahmutbeyaz on Create a Motion Profile
CODESYS Forge

(Post)
Dear All, I hope first to get notice and somebody answer my question. How can I create a motion profile with the axis following it (once or periodically)? As my research shows, Schineder has a UI-based (Motion Sizer) program that helps create a motion with different configurations, which is Codesys-based. I need to create a motion profile based on position, changing the speed. (i.e., 0-300mm moves with 300 mm/s, 300-400mm moves with 500 mm/s, 500-800mm moves with 1000 mm/s, and 800-0mm moves with 2000 mm/s). MC_PositionProfile does it time-based, which is not working for me as the axis may not stabilize the position in time, which may cause a big failure in the system.

CODESYS Forge

Yes, I tried to do what you put in the first code. However, I have a problem with that and that is that the inputs must be declared with the type. I have many data types running in my code (real, int, uint, bool) and I can't put them in the same function, another thing is that I need to instantiate that function for everything I want to write to the slave. You put a for to 200 but it means that it has to be the same data type and inside the array, but I want to get them individually. I'm struggling to do it in a good and efficient way like wago's E-cockpit does. in the first screenshot you can see, you simply type in value, change the package of things you want to write in value change and it does everything by itself automatically, without comparing any old and new values and even less having the need to activate a bool. , it is perfect.

You could try using the VUM_UserGroup struct from the VisuUserManagement library. I haven't tried this, but there is a variable for tAutoLogout to set the logout time.

Dear, When I use "__NEW" to dynamically create the object "Object_1", and assign this object "Object_1" to another object "Object_2". At this point, I use "DELETE" to release the object from "Object_2". At this time, I cannot judge whether the object has been released normally through "Object_1" (in fact, the object has been released theoretically). Thanks for you help.

have a look at UNIONs. With a union you are able to write single bytes to the same adress area which belongs to a float variable at the same time. I like to do a lot of convertions belonging to interfaces and fieldbus in this way, f.eg. word / byte swapping etc.

We are having issues right now, and I just stumbled on that post. It seems to me you are saying your Linux ARM control is RPi 5-compatible, but the one you sell specifically for RPi is not. The fix you are proposing requires customers to re-purchase a CODESYS licence. Is there a time frame for that to be fixed?

dhumphries, I changed the datatype this time from BYTE to USINT (because that's what my adapter is sending: array of uint8_t). The text "New Help String" you saw in previous screenshots is just the description of the input/s (it can be anything). I also looked into the logs (see attached) for that ! sign next to the device, I found that connection is being timeout. I tried some suggestions from online such as increase the RPI but still got connection timeout issue, also by changing the datatype, I still don't see incoming data from the adapter, although its visible on wireshark. thanks,
