Control of our CAN modules
Our RAW CAN modules can be controlled in two ways:
1. Auto TX/RX mode
2. DELIB command mode
1. Auto TX / RX mode
This operating mode allows the module to process CAN packets automatically without the need for an additional control PC. Configuration is very simple using the ICT tool and requires no programming knowledge.
Automatic transmission (TX mode)
Auto-TX mode allows automatic, cyclical transmission of CAN packets to other bus participants. The module’s digital and analog input signals can thus be forwarded directly to other devices.
As an alternative to cyclic transmission, trigger events can also be defined. This means that a CAN packet is only sent, for example, when a CAN message has been received on a specific CAN ID.
TX mode configuration
The following settings can be configured:
- Enable/disable TX mode
- Trigger mode
- Interval
- Use extended ID
- Send to CAN ID
- TX mode
Automatic receive (RX mode)
In Auto-RX mode, received data packets are forwarded directly to the analog or digital outputs of the module. For example, relay outputs can be set on the module via another CAN bus participant.
RX mode configuration
The following settings can be configured:
- Enable/disable RX mode
- Use extended ID
- Receive from CAN ID
- RX mode
2. DELIB command mode
In DELIB command mode, the module’s registers are accessed via a CAN protocol developed by DEDITEC. The module expects the CAN messages on a CAN address specified in command mode. Read and write accesses with different data lengths (BYTE, WORD, LONG) are possible. Details on the protocol structure and register assignment can be found in the “Protocols & Register Assignment” manual in the download area.
