Post by edepalos on Text list from sd card
CODESYS Forge
talk
(Post)
Hi guys, I have a textlist in my project which is working just as expected in a drop down list. I would like to move this text list to a sd card and access it from there, because I want to ease the editing of the contents of this textlist. I'm imagining a solution like the operator shuts down the plant, takes the sd card out, edits the textlist on the card with a windows machines notepad, then reinserts the card in the PLC and restarts the plant, having the new content of the textlist populating the dropdown list. I'm sorry that I'm asking you to spoonfeed me, but I did not find anything straightforward to do this... I saw in the Project>Project settings>Visualisation a relative path thingy, but I have the plant in operation and I would not like to make 100 trial and errors right now... I'm also not interested in SysLib file read commands and stuff, I would just like to access the file from the cards part, I don't want to replace its contents dynamically or such... nor I have language files or recipes... Thank You in advance! Br, Ede

Has anyone used a library related to websocket client? I will be in charge of websocket client in CODESYS, and websocket server in python. In CODESYS, I will use WebSocketClient(FB) WebSocketRead(FB) WebSocketWrite(FB) to configure the client, Does anyone know an example of how to use it? Please help me.

Post by macros8 on Alarm Management - latched variable represented as Text list
CODESYS Forge

(Post)
Hi, I haven´t noticed you put the comment here. I thing it´s a bit different. What I want is to have detail errors of technology in data type e.g. INT. This variable I would latch to the corresponding error msg but I would like to get it convert to text from the text list and not keep it in INT form. Example. Main error Valve Error: SubErrors 1 - Both sensors 2 - Not retracted in time 3 - Not pulled out in time In HMI Main error + latch SubErrors => "Valve Error: Both sensors" The benefit is that text lists are part of translation and can be easily manipulated. I know I can create whole string msg in PLC but then, it lose advantage of Alarm management. Thanks. M.

Problem solved The client modbus cycle time was linked to a task at 500ms. Whereas the channel modbus was at 200ms. Certainly problem of packages synchronisation. I let the client modbus cycle time to be handled by itself (See attachement) --> "Use the bus cyle time parameters" (traduce from french) See attachement

Hello, I would like to know, if it is possible to use codesys for a visualization of parameters in a controller (not PLC) not programmed using Codesys. I intend to use codesys for the visualiztion, and do not know yet what I may require.

Same for me. I have problems with UAExpert too. Can't see the Current Value of Enum and can't control. Did some Tests with Python opcua library. Not working with the communication manager so far.

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.
