ADwin-Pro II Hardware, manual Dec. 2018
5.8.5 Pro II-CAN-FD-2 Rev. E
The module Pro II-CAN-FD-2 Rev. E has 2 CAN FD interfaces.
Each module is equipped with a freely programmable TiCo processor, which
has full access to the CAN interfaces. Find more information about use and
programming of the
TiCo processor in the TiCoBasic manual.
The manual is divided into the following sections:
– CAN FD Controller
– TiCo processor
– Hardware design
– Message Management
– Module revisions
– Programming
CAN FD Controller
The CAN bus interface is equipped with the Microchip
®
CAN controller
MCP2517FD, which works according to the specification ISO 11898-1. You
program the interface with
ADbasic instructions, which are directly accessing
the controller’s registers.
The controller supports both CAN 2.0B (high speed) and CAN FD (also mixed
mode with CAN 2.0B).
Messages sent via CAN FD bus are data telegrams with up to 64 data bytes,
which are characterized by so-called identifiers. The CAN controller supports
identifiers with a length of 11 bit, 12 bit, and 29 bit. The communication, that
means the management of bus messages, is effected by 32 message objects.
Message objects 1…31 run as FIFO (first in, first out) and can be configured
as input or output; message object 0 is a transmit queue which transmits mes-
sages with lowest identifier first.
The controller can be set to frequencies of up to 8Mbps (data bit rate) or 1Mbps
(arbitration bit rate). With CAN 2.0B the max. frequency is 1MHz. The CAN bus
is galvanically isolated by optocouplers from the
ADwin system.
TiCo processor
The module provides the freely programmable TiCo processor with 28KiB pro-
gram memory, and 28KiB data memory. The TiCo processor has access to the
CAN controller. Find more information about use and programming of the TiCo
processor in the TiCoBasic manual.
If you store a TiCoBasic program in the TiCo bootloader, the program is auto-
matically loaded into the TiCo processor and started on power-up. Thus, the
module can run on its own and independently from the CPU module of the
ADwin-Pro II system.
