    I wanted to read all bytes using the i2C_Master.Read method. I could not get. On the I2C devices tab, I see at the beginning of the address -1 after the i2c_master.read method is performed in the address changed. The variable from the bytes is 0, then the bytes are not received. What to do? How to get bytes?

    Hello everyone, I need to develop a UPS for a Raspberry Pi 4 with CODESYS implementation. This UPS should guarantee that the PLC is able to shutdown and push the retain-variables to a connected NVRAM. But because of missing space it needs to be configured as small as possible. Does anyone have some typical times for the Runtime to completely shutdown? Thanks for your answers.

    Hello, I have added MQTT Client library to my project from Codesys Library Manager. When I would like to call MQTT Client FB from Input Assistant, the FB is not found as shown attached screenshot. Why I dont call the FB? Please help me. After library addition, library names has blue underline. Is it causes related problem?
