Post by rcaponi on Codesys Control RTE V3. Remote Control ^{CODESYS Forge talk (Post)}
Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi

Post by valec on Connect local Asem HMI runtime to local Codesys Control Win V3 x64 ^{CODESYS Forge talk (Post)}
I have a project made on a PL700 PLC with Codesys and an Asem Premium HMI panel. I don't have access to the physical PLC right now, so I'm trying to use Codesys Control Win V3 x64. I created the application and loaded "Codesys Control Win V3 x64" without errors, then I activate "Start PLC" from the tray. Asem cannot connect. I tried to use "localhost" or the local IP address and it doesn't work (it's the "CoDeSys Soft PLC Communication Driver"). I need to connect my local Asem runtime to a virtual Codesys application on my PC. How can I do it?

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
I have a version of codesys 3.5.16 on my local machine and a vm. The local machine has loads of codesys versions and libraries installed etc. I can open the FPosCR_Example_Project_SP16_patch1 project on my vm without any errors. On the local machine I get the error C0077: unknown type IoDrvEthercatLib.ETC_CO_SdoWrite. I can, on the local machine, declare a var of type IoDrvEthercatLib.ETC_CO_SdoWrite and include it in the code without adding an extra error. The problem only seems to affect the library. This is seems more an issue with my codesys set up rather than something with festo. I would like to know the possible causes. I understand most of the library manager features but it's not clear how to find the cause. Thanks

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

Post by sean-barton on Function block method default arguments ^{CODESYS Forge talk (Post)}
I have default arguments specified for function block methods but when calling a method, an error is produced requiring me to supply all the arguments despite there being default values. According to the online documentation, under section "Calling a Method" and subsection "argument passing" of the following link: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_obj_method.html "Passing an argument for an input ... can be omitted ... for which a default or initial value was specified in the declaration..." I have found this to be the case for all Codesys IDEs I've used, 3.5.11, 3.5.16, 3.5.17, 3.5.19. Am I missing something?

Post by sawicpx on CANbus Remapping PDOs During Runtime ^{CODESYS Forge talk (Post)}
Hello, I am working on an application where I need to remap PDOs to a different CANopen object during runtime depending on what value is at a specific register. I have gotten to the point where I put the device into Preoperational State using the CIA405.NMT function. I then reconfigure the PDO 180x and 1a0x obejcts usings SDOs to point to a new canopen object on the device however when I go to restart the Device from PREOP to OP using the CIA405.NMT function the device is reset back to the original configuration as per the initial setup. I am wondering is there any way to change the PDOs at runtime is there some more functionaility I can access to do this. Any direction is appreciated!

Post by phoward131 on Numpad decimal value requires leading zero ^{CODESYS Forge talk (Post)}
I have noticed on the standard numpad dialog, if a user enters a purely decimal number (ie '.6'), the numpad will not accept the value but gives no indication. One must type a leading zero (ie '0.6') in order for it to work. Is there a way to correct this so that a user can just type the decimal value?

Post by mondinmr on Jitter problems on imx8 ^{CODESYS Forge talk (Post)}
SOLVED!!! In this imx8 max_cstate=1 in kernel boot parameters is not working! We found a workaround: #include <stdio.h> #include <fcntl.h> #include <unistd.h> #include <stdint.h> int main(void) { int fd; uint32_t value = 0; fd = open("/dev/cpu_dma_latency", O_WRONLY); if (fd < 0) { perror("Error opening /dev/cpu_dma_latency"); return 1; } if (write(fd, &value, sizeof(value)) != sizeof(value)) { perror("Error writing to /dev/cpu_dma_latency"); close(fd); return 1; } while (1) { pause(); } } This simple code launched before CODESYS do the same work! Now jitter is identical as measured by cyclictest!

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello Vincent, I don't have 75 channels but it works for me as described above without any problems. There is also a parameter MAX_MODBUS_CHANNELS in the library parameters for the IoDrvModbusTCP module. The default value there is 100. Perhaps you are reaching the limit there? The value can be adjusted accordingly. I assume that this value is not accepted in the input dialogue and therefore the 'fixed' limit value 10 is used.

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Hello, I am trying to implement a FB to make JSON formatted WSTRING type message using JSON Utilities 1.9.0.0 included in the IIoT library. In my case, I want to set some objects or arrays and set values to them later. But when I wrote as the sample below, // init builder builder(pJsonData:=pJsonData, diRootObj=>diRootObj); // set the 1st key to root diKey1 := builder.SetKeyWithArray(wsKey:="key1", diParentIndex:=diRootObj, eError=>eError); // set a value to the 1st key wsValue:="value01"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey1, eError=>eError); // set the 2nd key to root diKey2 := builder.SetKeyWithArray(wsKey:="key2", diParentIndex:=diRootObj, eError=>eError); // set a value to the 2nd key wsValue:="value02"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey2, eError=>eError); // set a value to the 1st key again wsValue:="value03"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey1, eError=>eError); // set a value to the 2nd key again wsValue:="value04"; builder.SetValue(Value:=wsValue, diParentIndex:=diKey2, eError=>eError); // write build result writer(xExecute:=TRUE, pwData:=ADR(wsResult), udiSize:=SIZEOF(wsResult), xAsyncMode:=FALSE, jsonData:=pJsonData^); the result was: { "key1": ["value01"], "key2": ["value02", "value03", "value04"] } while my expection was: { "key1": ["value01", "value03"], "key2": ["value02", "value04"] } Inspecting pJsonData^, JSONData itself seems to be ok, so I believe the issue is something caused by the writer FB. Does anyone know how to fix it? Thanks,

Post by wbj0t on connect IDE to plc that uses modem ppp ^{CODESYS Forge talk (Post)}
Hello everyone! I have an PLC device that uses modem ppp connection to the internet with white IP. Device PPP connection with modem operator established, so I can connect to this device via SSH also within Codesys IDE (check version, info, etc...) BUT, I cant establish connection to this device in the device gateway options for application upload and debugging. How can I do this? Im trying set my device remote IP and port 11740, but, as I understand, it is wrong decision, because the next logic in this connection: local W10 service (Codesys Gateway) listen on 1217, then (some how) this service scanning local networks for seeking any local IP which listening on port 11740, and then connects and writes there. OR IM WRONG?:) W10 tool 'Test-NetConnection' with parameters 'ip -Port 11740' succeeded with True. Need some help, please :)
