Post by brell on Automatic xExecute NBS.TCP_write ^{CODESYS Forge talk (Post)}
I've recently started experimenting with CODESYS for a project and am fairly new to it. I'm currently working with Function Block Diagrams (FBD) to set up TCP communication between a server and a client, where the client is implemented as a Python script. Once the communication is established, my connection status changes to True, which is the expected behavior. My challenge arises with the TCP write module, which requires the xEnable_write flag to toggle between True and False. If xEnable_write remains True, the module only performs a single write operation. To address this, I introduced a falling edge trigger (F_TRIG), expecting it to help in toggling xEnable_write and it does, However, I've encountered an issue where in the beginning after connxion established I need to manually set xEnable_write to True for the system to work as intended. I'm looking for a way to automate this process so that xEnable_write becomes True automatically upon establishing a connection . Initially, I tried setting xEnable_write to True from the start, but this approach didn't work well since it left the flag permanently True, preventing further toggling. I also experimented with using a TON timer, but I faced similar issues. I am seeking a solution that automatically toggles xEnable_write between True and False after a connection is established, ensuring continuous write operations without manual intervention. Any advice or guidance on how to achieve this would be greatly appreciated."

Post by rickmotion on Opening and saving files with fileOpenSave dialog ^{CODESYS Forge talk (Post)}
I have a customer that types in machine programs in a text file for machines and lets the machine execute it. In the old situation they can open and edit these files in a winform application. Now I want to move this to codesys. What I need is a simple way to open, close, save, edit the machine file in codesys visualisation. I want to use the fileOpenSave dialog. But don't understand how it works. I have the file transfer example and some other examples. But it is hard to figure out how the part with the file dialog works so that you can select a folder or file. Does someone know how that works?

Post by transmin01 on SafetyApp - Exchange 8 bits from EtherCAT Safety Module to PLC mapping issue ^{CODESYS Forge talk (Post)}
Hi, I am using an "Exchange 8 bits from EtherCAT Safety Module to PLC" module which allows me to create tags in the safety environment, but how does this map to the standard PLC program? There is no entry in the IoConfig_Globals variables list. Regards Trevor

Post by davidbo on How to switch between dynamic IP address and dynamic? ^{CODESYS Forge talk (Post)}
I want to make an application with a UI for CODESYS Control for Raspberry Pi MC SL which make it possible to switch between dynamin and fixed IP address and to set the IP address. However I do not know whether that is possible?

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.

Post by docker on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
Hi, i am interested in this thread and have tried a couple of the above examples in to determine remote webvisu access. I am having trouble getting the lastusage variable to refresh during runtime? It seems to only log the last usage at initialisation and that is it? how do i gain ongoing access to the time variable as the code is running? Thankyou.

Post by open on How to create a stopwatch? ^{CODESYS Forge talk (Post)}
Hi @ph0010421 and @Ton, Is it possible to program a stopwatch to measure a system running time when it is turn on, and pause when the system is turn off. I tried your examples when stopped, the elapsed time will then be calculated, but i need the time to be continuously counting. Warmest regards,
