Correct, my Device architecture says "None" is this position. A missing config somewhere?

Post by rik123456 on Alarmmanagement – Dynamic Alarm List
CODESYS Forge
talk
(Post)
Hi, I had a question about alarm management in the CODESYS visualization. I am currently investigating to what extent the alarm visualization can be built dynamically. In my program, I have developed a motor block that is used for multiple motors. When the emergency stop of one or more motors is activated, the corresponding motors are displayed in the alarm list (see image). This works quite well. I achieved this by linking variables to a latch, after which a piece of code displays the motors that are in emergency stop. My question is: do I need to create a separate latch for each motor or can I use a single latch to display multiple alarms of a motor underneath each other? This would then look like this: Time…: M1 Emergency Stop Active Time…: M4 Emergency Stop Active

Hi Reinier, What usually works for me is settings it up in the following way: In the sender block make sure that the list identifier is unique for the whole installation (this is only relevant when you have multiple senders in 1 network). When you are linking the NVL to a file make sure that the path to this file doesn't change. In my experience the NVL stops working when you change the working directory and afterwards open the NVL in de Codesys IDE. If this doesn’t apply to you application, you could also try to change the port number, maybe there is an other process making use of port 1202. Kind regards Alex

Post by alex-n on Problem with keeping up the distance between two axes
CODESYS Forge

(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)
Hey there! I am currently running into the exact same issue (and have also posted to a similar post here: https://forge.codesys.com/forge/talk/Engineering/thread/c45929e2f1/#e27f). The JsonData object has all inexes & parent indexes in the way I expect, everything is correctly "linked". It purely seems that the writer is incorrectly parsing said JsonData, not based on parent & child index, but on something else that breaks it and puts things at the root, instead of the specified parent index. Did you ever manage to find a solution, or another way of achieving your JSON composing? I'm currently working on Codesys V3.5 SP19 Patch 7 with IIOT Libraries SL 1.13.0.0, specifically JSON Utilities SL 1.13.0.0 (to send requests to APIs with JSON bodies using Web Client SL 1.13.0.0).

I still have the same problem with Codesys 3.5 SP18. Initially, my project is ~5 Mo. I work on it for like 3-4 days and it goes up to ~10Mo. If I make an export of the project and import it in a new empty project, it goes back to approximately 5 Mo. Why is it doing this ?

Post by ryandmg on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS)
CODESYS Forge
talk
(Post)
Hey Everyone, I'm having a bit of a struggle finding settings that will reliably maintain a connection between the webvisu and a touchscreen client. Every so often the HMI disconnects and will perpetually display the red spinning arrow with the "Error Happened, Will resume automatically" text. Power cycling the HMI to force a reconnect will re-establish comms. It seems to happen during periods of inactivity if that's a clue. From what I've gathered so far this seems to have something to do with the webvisu update rate, buffer size as well as the visu task scan rate. We first tried the default settings as follows: Webvisu Update Rate: 200 ms Webvisu Buffer Size: 50,000 Visu Task Scan Rate: 100 ms Priority 31 Other Tasks for Reference: Main Task Scan Rate: 100 ms Priority 1 Alarm Manager Scan Rate: 50 ms Priority 31 Ethercat Task: 4 ms Priority 1 This would disconnect some what regularly. We then made the following changes to try and stabilize: Webvisu Update Rate: 150 ms Webvisu Buffer Size: 75,000 Visu Task Scan Rate: 75 ms Kept other tasks the same. This seems to disconnect even more frequently. Also for reference the network is very small and only consists of the PLC, a small switch and the HMI. We're also not controlling frames from outside the visu program itself. The frame changes are all done natively. Any suggestions to get this to stop disconnecting? Oh and whatever the issue is the log does not record it. Figured I would ask here before opening a ticket. Thanks in advance for your help!

You can use the (open source) FTP client in Forge. This works on 64 bit systems. See: https://forge.codesys.com/prj/ftp-client/code/HEAD/tree/ As this is open, the idea is that when you use it and make improvements to the source code, that you also commit this in a branch so others can also benefit from it.

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 or OR.
