Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Hello, We have a problem with CodeSys on a raspbery pi with an ADS1015 analog to I2C module. It can't find the I2C device on the i2c bus, it says No I2C Driver Found. When we use the RPI terminal we can find the I2C device and read it out. The i2c-1 bus is also accessible from codesys. The device address of the Analog to I2C module is 0x48. Can someone have a look what the problem is? i submitted the screenshots in the attachments. i also include the device description and library.

Post by albzen on EtherCat Slaves diagnosis ^{CODESYS Forge talk (Post)}
Hello everybody, I'm working on a RunTime Plc (Codesys 3.5.16/18.20) connected to an EtherCat bus with many devices. The bus has some communication fault but I don't know how understand which is the device or the cable that has the trouble. To understand the cause of the problem I would like to read the WKC (Working counter) of the devices (0x0300...0x030C), how is explained in EtherCat documents, but it seems that the read of the counter is disabled. Attached there is an extract of the Ethercat document. Can anyone give me some advice about how and with function can I read it. Thank you in advance!
