12.4 Connecting an external Control Device
You can connect an external control device to your TC.ACS device as a remote control via the TC.ACS.CANmp
interface.
To connect an external control device via the TC.ACS.CANmp interface, do the following:
Physically connect the external control device to the TC.ACS device via one plug, either X652 or X653 of the
TC.ACS.CANmp interface with an appropriate CAN cable.
Unless the other plug is connected to another CAN device, terminate it with the related terminal resistor.
12.5 Configuration of a CAN Protocol
To use the CANmp interface a CAN protocol must be configured and written to the TC.ACS device.
Within a CAN protocol, a maximum of 50 messages can be configured and for each message a maximum of 4
signals (each 16 bit). The length of a signal may vary between 16 and 64 bit depending on the used data type. The
number of configurable signals in a message may be different, because the payload has a maximum length of 64
bit.
Here, a message can be configured with respect to the following attributes:
• CAN ID
• DLC (data length code, number of bytes of payload)
• Type of message, i.e.:
RX message (receives a message)
TX message (transmits a message), including the following kinds:
- Cyclic message (transmits a message at regular intervalls)
- Sync message (transmits a message after receiving a specified number of sync signals)
- SyncID message (transmits a message after receiving a specified syncID)
• Structure of included signals
Start bit
Length
Byte order
Data type
Factor for multiplication or determination of the number of decimal places of the signal value for the data
type integer
With respect to the TC.ACS.CANmp interface the following applies
:
- It is fully isolated.
- It fullfils the ISO 11898 standard.
For more information on configuring a CAN protocol and writing it to the TC.ACS device
see the user manual of the CANmp Configuration Tool.
