The Industrial Raspberry Pi Forum

Dear RevPi Experts,

We would like to use CAN-Open climate sensors (from Zile.de: https://zila.de/en/products/can-bus/can ... ate-probes).

We already have the RevPi ConnectPlus and the CON CAN expansion module.
I know that CAN-Bus is the lower level protocol used in CAN-Open.

1>> Can the CON CAN expansion module be used to get data from a CAN-Open sensor?

2>> Or do we need to get the CANOpen Gateway (Item no. 100070)?


Thanks,
Guss

Hi shot to say the CANopen Modular Gateway Module is a slave the RevPi Con CAN be used as a master:

Hi Dirk,

Thanks for your reply and the shared web site.

To make sure that we understood the information supplied. What you are saying is: the CANOpen module cannot be used as is, because it is a slave by default. However, if Codesys Runtime software is used, it can be configured as a Master.
1>> Is this correct?

In the shared, web page why are BOTH the CON CAN module and the CANOpen modules used (https://revolution.kunbus.de/tutorials/ ... en-master/)
2>> In order to read data from CAN-Open sensors, do we need BOTH the CON-CAN module and the CAN-Open gateway modules?

3>> Can this sensor data be obtained from the CON CAN module because it is a MASTER - without needing the CANOpen gateway module?


Thanks for any help and feedback.

Best Regards,
Guss H.

Hi

1>> Is this correct?

No, all the Modular Gateway Modules like the CANOpen are working as a black box. So you don't have access to the fieldbus from the RevPi. You configure it in PiCtory like other Modules and there you have just input and output data.

In the shared, web page why are BOTH the CON CAN module and the CANOpen modules used (https://revolution.kunbus.de/tutorials/ ... en-master/)
2>> In order to read data from CAN-Open sensors, do we need BOTH the CON-CAN module and the CAN-Open gateway modules?

No this tutorial uses both modules to provide an example how to echange data between a Master and a Slave.
You just need the Con CAN Module togehter with a RevPi Connect Module or RevPi Connect+ Module to access the data from your CANopen slave.

3>> Can this sensor data be obtained from the CON CAN module because it is a MASTER - without needing the CANOpen gateway module?

Yes exactly but just together with some Master application i.e. Codesys.
