CAN bus communication between PLC and LMS SCADAS Mobile

Experimenter

Hello,

 

Is it possible to establish CAN bus communication between LMS SCADAS Mobile SCM202 device and S7-1200 PLC using ADFWeb HD67606-A1 Profinet/CAN as a gateway between PROFINET and CAN bus netowrks?

The idea is to send data from PLC S7-1200 to the LMS SCADAS over ADFWeb PROFINET/CAN converter.

 

The question which arises is how to set an address of SCADAS device, since configuration of CAN frames sent from ADFWeb HD67606-A1 requires to enter COB-ID number of the device, converter is sending data to (which in this case is SCADAS)?

 

This is data sheet of ADFWeb gateway:

Sorry, the only way to communicate to a CAN device is through the CAN interface and using a DBC file to decode the data string.  This article from the Community site describes the process.

Hello JDietz,

 

Thank you for your reply.

I am creating DBC file using Vector CANdb++ Editor. In LMS.Test.Lab there is a field called Source Address (when you select Channel Setup). What kind of address is that? The address of device which is communicating with SCADAS?

Here is some information that we found in an online search:

 

Each device on the network will be associated with at least one Name and one address. However, multiple device Names and multiple addresses may coexist within a single ECU. For example, an engine and engine brake (retarder) residing in a common device with a single physical bus connection. The device address defines a specific communications source or destination for messages. The Name identifies the functionality and adds a unique instance number of that functionality when multiple devices of the same type coexist on the network. Only 254 different devices of the same type can coexist on the network due the address limit. Address 255 is reserved as a global address for broadcast and address 254 is reserved as the “null address” used by devices that have not yet claimed an address or failed to claim an address.
