Post by talhaali on Alarm Manager: ^{CODESYS Forge talk (Post)}
Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

Post by wb16 on Visualisation generates "Unresolved reference" ^{CODESYS Forge talk (Post)}
Hello Zol6, Have you solved this issue? I use Festo PLC CPX-E-CEC-C1 to create alarm monitoring project. In CODESYS V3.5-SP18 I used the Alarm Storage object and have the same problem. Is it the PLC that is not compatible or the version of the library is not match? Best, wb16

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice

this is not easily. From Point of SL-Licenses Codesys didnt provide the informations how to do. We created an own CDS-Component for that Behaviour. This Informations are available for OEM, if you are an OEM you can find the Informations in the RTS-Documentation.

Post by vitorp on Visualization Toolbox in German ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys. I installed it on my computer and set the language to English. Most of the localized text appears in the correct language, but the Visualization Toolbox and the element properties are in German. I haven't found a way to change them to English. Can someone help me with this?

Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
I've been searching through these libraries, syssocket and net base services and they all seem to use the same structure for IP address for the connect function, SOCKADDRESS. At a glance, it doesn't look like that'll work, maybe it's just missing in the documentation somewhere?? I'm wondering if anyone has done it.

Post by gatto on variables between two applications ^{CODESYS Forge talk (Post)}
Hello, I'm experimenting with two applications. I was able to start stop applications with the CmpApp library. Currently in my test the variables declared in the first application are not visible and writable in the second. I ask if there is the possibility of having variables that are visible both in the first application and in the second.

I have now conducted some tests. The problem occurs when the Python script establishes an OPCUA connection, even if I only establish the connection without reading or writing any data. Is there another way to exchange data between Python and CODESYS without having to put in a lot of effort?

Im using SysCom ver. 3.5.17.0 and seem to have the same issue on a Raspberry Pi. It's not waiting for the requested number of bytes, no matter if "ulTimeout := SYS_INFINITE" or any other value. The only solution I have found is to stall the program to allow the serial port to recieve the data.

What worked for me with this error was to go to Tools -> Update Raspberry Pi, select Install, and from the popup screen, there are options to change your installation (I changed it to single core, instead of multicore), and I was then able to connect to my Rpi 4.

Hello, I have an OPC-UA server with an information model. For many values, there is a defined range (e.g., 0 to 100). If a client enters a value outside this range (e.g., 120), the StatusCode should change to Bad. How can I accomplish this? Any help is appreciated! Thank you in advance.

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work). In general: - Motion function blocks have to be called until they report 'Done', 'Error', 'CommandAborted' or a subsequent motion FB with BufferMode=Aborting is started in the current cycle. - Setting the Execute input to FALSE will not abort any ongoing motion of the motion function block. For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. I think the error SMC_FB_WASNT_CALLED_DURING_MOTION is only a follow-up (and misleading) error that results from the axis not being in operational state anymore (bus problems). Is there an error 'regulator or start not set' in the device log before the error 'motion generating FB wasn't called for at least one cycle'? Which error does the respective function block (Halt.ErrorId) report?

Post by dkugler on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
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.

If i leave the auto reconnect on it still doesn't talk to the rmianing devices and if i turn Auto reconnect off it locks up. Any help would be appreciated. Paul.

Post by maldus512 on How to adapt Codesys Control SL to custom board ^{CODESYS Forge talk (Post)}
Hello everyone, I have been given the task to develop I/O drivers for a custom made, Linux based board to allow for Codesys applications to run and control the hardware. I have successfully installed Codesys Control SL for ARM/Linux and tested it with a simple demo application. Now I should start interfacing the runtime to the actual hardware; I should be able to interact with 2 RS485 serial ports, a few GPIOs and an I2C port, all of which already have the corresponding /dev/ interface in the Linux system. I am having trouble understanding how it should be approached. I have found sporadic references that fail to lead to a really comprehensive documentation. For example: The store page (https://store.codesys.com/en/codesys-control-for-linux-arm-sl-1.html#options) mentions a "runtime package" that should allow "Integration of existing C code" and "Usage of local I/Os", which seems exactly what I need to interact with custom peripherals. I have found no further reference to Codesys-C interpop. The Codesys Help page for the runtime package has a page on the "Development of Drivers" (https://content.helpme-codesys.com/en/CODESYS%20Control/rtsllinuxrbpdriverdevelopment.html) that suggests to either "Implement a function block" or "Implement I/O drivers". Those in turn lead to this page (https://forge.codesys.com/drv/io-drivers/doc/Generic/) which describes briefly an XML schema to describe new devices; unfortunately, it doesn't mention what to do with such a description (i.e. how does the runtime know about it) or how it is in any way connected to the actual hardware. Could anyone give me some pointers? I should also mention I have no prior experience with Codesys, so maybe I'm missing an obvious answer.
