Post by shaun on GAMP 5 and 21 CFR Part 11 ^{CODESYS Forge talk (Post)}
Good day I have been asked to do a project. It is for a pharmaceutical application and data needs to be logged. The spec calls for the control system to comply with GAMP 5 and 21 CFR Part 11. From what I can find online it's got to do with electronic records and validation. Has anyone developed any software using this or are there codesys librarys that can make my life easier in writing this code

Post by kenth1973 on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
My MC_Phasing FB was stuck in iPhasingState=1 and error output HIGH on one axis. I could manually overwrite the state to 0 in the instance data. During normal run I see the state change from 0 to 10 to 100 back to 0 (maybe more states that I couldnt catch with the naked eye) But - what are the states numbers and their different explenations? This is not explained in the FB guide on codesys. (the pictures show state = 0 after I reset)

Masters, I need your help. I can explain in different way. I can get the name and comment of parameter if i use "VARINFO", but right now I want to get name and comment of FB from inside one. I can get the name to use the "{attribute 'reflection'}" but I don't understand how to get comment? Do you have any idea how to do it? Thanks

Post by pernockham on How to recognize licenses SMALL, MEDIUM, LARGE by CmpCodemeter ^{CODESYS Forge talk (Post)}
Solved finally, in short by: listening to eventId = EVT_CmpMgr_LicenseState, make a callback, extract the event-parameter which contains the RUNTIME_LICENSE_STATE. This gives me the license state as LICENSED / LICENSED_LOS / DEMOMODE etc. What Im not certain of at this point is this the aggregation of all three licenses or just the RUNTIME? Ie, what if my CONTROL-license is ok but my Visu-license is to low, will that set LICENSE_LOST, or would I need other listeners to find out if my VISU will shut down?

Third update. I figured that even knowing the level of the license, it will not tell me if its level is enough for the current application. There must be some other way to find this out? I see a component CM write in the Log if starting without license-dongle. "License lost - time left.. " Can I access this CM to check status from inside the application? This function is essential, why is it so hard to find info about implementation?

Post by bmatlove on Re-create CoE online window in Visu ^{CODESYS Forge talk (Post)}
Hello, I am trying to re-create the CoE online window within a Visu for purposes of checking and interacting with device parameters occasionally for maintenance purposes. To minimize reliance on using the IDE for misc interactions. Ideally, I would like to exactly mimic the CoE online window within the IDE. I assume that it uses a few tricks to minimize overhead, such as only polling registers which are within the visual scope, for example. I'm afraid it might be too much to ask for a pre-built drop-in Visu module to exist for this task. Do I have any options aside from manually re-creating all the logic to do this, relying heavily on SdoInfo function blocks? Is there a way for me to reference the device ESI file to shortcut the process of determining how many registers there are and getting the address for each?

Hi, I am new to CODESYS, and I want to program a new FESTO, but I am getting this authentication screen. I don't remember the password. I tried with Administrator/Administrator and some other defaults I found online but nothing works. I also tried searching for CODESYSControl_User.cfg and many other recommended directories but I dont seem to have any of them (like CODESYSControlWinV3x64) Could you please help me understand what I need to reset? Thanks a lot

Can anyone shed some light on this issue im having. at random, sometimes days, sometimes weeks or months. i get this error and have to reset the plc. Im using a Weintek HMI with ethernet/ip remote io and vsd. i have tried increasing my task times and watchdogs. and when i view my PLCload in the shell its normally around 3-4%, highest ive ever seen is 7%. Nothing i do seems to help the issue. Could the HMI's Codesys CPU be getting to hot do to high ambient temp?

Post by russells on Codesys ControlWinV3x64 with EtherCat Slave ^{CODESYS Forge talk (Post)}
Hi there I am running Codesys ControlWinV3x64 (Patch 4) on my laptop for demonstration purposes but I am unable to get connection to the EtherCAT master and slave device. This is the process that I have followed: * Installed NPCap. * Added the xml file for the SMC slave device to the Device Repository. * Activated Control Win SysTray x64 and selected Start PLC. * Scanned the network for the local device (my laptop). * Added an EtherCAT master to the project and scanned the EtherCAT master for the Network and then selected the correct network. * Selected "Scan for devices" to identify the connected I/O. * Add the SMC EtherCAT slave manually because I was unable to scan it in. * Selected "Scan for devices". I have followed the steps described above but I can't scan in the EtherCAT slave or connect to it. I thought this situation was unique to the EtherCAT slave but I have also tried the same for an EtherNet/IP slave using the Ethernet Adaptor and EtherNet/IP scanner and I am also unable to scan in the device or activate the EtherNet/IP network. Any assistance will be appreciated.

Hello, I am currently scaling 4-20mA signals and the scaled output (temperature) has to be sent via modbus protocol to a tool like doctor modbus or modbus poll. I have defined my inputs as real as and the output is also real, but to send this output via modbus it has to be of word. So how will i convert real into word and then send the generated output via modbus?

Post by timvh on HTML5 visualization controls disabled on CODESYS Control for Linux SL - overlay not supported? ^{CODESYS Forge talk (Post)}
I would suggest to install the latest visualization and visualization add-ons. Go to Tools - CODESYS installer to updates these add-ons (or just start the CODESYS installer through the Windows start menu). After installation, restart CODESYS SP22 and update the project to use this new visualization profile (you can update this through the menu Project - Project Environment - Visualization Profile).
