Post by siscu on Raspberry i2c master device ^{CODESYS Forge talk (Post)}
I want to implement an extended I2C master for Raspberry Pi Control. I was hoping for it to be as easy as creating a library with a FB that extends i2cMaster and associating it with a device following the forge drivers documentation, but I haven't managed to make it work as the driver behaves only as an i2c slave. I'm thinking this is because the forge forum only talks about extending i2c, and the master portion is omitted since most users won't want to add a custom one. I'd like to know if I'm doing something wrong. Is it really possible to make an I2C master extension device? If so, are there public examples we can check out? Any info on this topic will be appreciated.

I think this will not work. I reworked and used an int as source instead.

@eschwellinger That worked. Ran as Admin when starting Codesys. Great workaround. Thanks

no parameter seems ok but RS485 does only work with CODESYS if the send/receive is determined by hardware as I remember correct

as a workaround just plug your USB key to the CODESYS PC - and activate the ticket by the browser license.codesys.com

You could use the Modulo function to get the minute part from the total minutes: Minutes := TotalMinutes MOD 60;

Post by imdatatas on Unrecoverable SoftMotion state after switch to PreOp ^{CODESYS Forge talk (Post)}
Dear @alimans, Additionally, As far as I know since starting from Softmotion V4.18.0.0 automatic restart behaviour for an axis has been changed for this issue. See below explanation from release notes. "With CODESYS SoftMotion 4.18.0.0, the behavior of SoftMotion axes after a loss of communication to the servo drive has changed. Now, an automatic reinitialization is performed as soon as the communication is established again. Before, an explicit call to SMC3_ReinitDrive had to be performed. An example for a loss of communication is that the cable to one of the drives is unplugged." Regards, imdatatas

Post by mait-tim on Drive communication errors ^{CODESYS Forge talk (Post)}
With a machine I'm working with i get a communication error when I'm updating some softstop limits. As soon as I update the code the drives do not want to operate. Using the MC_readStatus I'm receiving errors as soon as i want to start a movement. Using MC_ReadAxisError i see that i receive error 131, no response. With a SMC3_ETC_ReadParameter_CoE i do not recieve any driver errors. Does anyone know how i can figure out what the error is and how to solve it. When i go back to the old software no errors occur. Im working with a legacy machine running a Beijer PLC with some Mitsubishi drives. running on Codesys 3.5 SP10. the runtime version is probably 3.5.3. The drives are all Ethercat Drives (CoE). All using the SM3_drive_ETC libary and the SM3_basic library.
