Hello everyone, I have developed a system on Codesys and I am using RaspberryPI (Codesys Contro for Raspberry PI). Maybe in the future it could be a comercial system. But today I saw this: Yes, I use the license exclusively for non-commercial purposes, in the field of education and research or for evaluation. What does this mean that license can not be used for comercial purposes? So all the systems that have been developed on codesys are not not usable because of this? regards
Hello, I have solved this. Bus Cycle Task has to be set to "Task" Always Update Variables has to be set to "Enabled 2 (always in bus cycle task)" Now it is working with normal speed.
Hello everyone, I am using RaspberryPI 3B as ModbusTCP slave device. Until now I was using Codesys Control fOR Raypberry version 3.5.14 and it was working OK. Now I have updated the Raspberry with Codesys Control 3.5.16 and Modbus is working very slow. Reading and writting into Modbus registers is very slow. What could be the reason? Best regards
Hello, I have an old RaspberryPI 2 model B with Codesys license. No I want to change the RPI with RaspberryPI 4. Can I transfer license from RPI2 to RPI4? regards
Hello everyone, I am useing ModbusTCP library with RaspberryPI. I am using Input registers as WORDs and BOOLs. There is no problem with words. I get a compile problem with BOOLs: Type 'BIT' is not equal to type 'BOOL'... Why BIT type? The digital type in ModbusTCP Input registers is BOOL. I do not understand this. Any solutions? Best regards
Hello everyone! I am using this port expander https://www.abelectronics.co.uk/p/54/io-pi-plus with 2 MCP23017 and I have a problem with outputs. If I startup my RPI and this IO board at the same time I can not operate with outputs. There is 5V on every pin on this board. But If I startup Raspberry PI first and this IO board in about 10s, I can operate with outputs normal. I can not understand why is this and how to fix it, so that this will work normal at startup of both (RPI and IO board). I am...

Hello, I have used this library and this example to use the MCP23017 as digital outputs, but there is no change on IO pins when I change the state (always 5V on pins). Why is there no change on pins? Regards
