The PISO-CPM100
gives a very powerful and economic solution of an active CANopen
master device with one CAN channel. It uses the NXP SJA1000T
and 82C250 to be the CAN controller and transceiver, which provide
bus arbitration, error detection with auto correction and re-transmission
function. The 16-bit on-board microcontroller with real-time O.S.,
MiniOS7, allows many features, such as real-time message transmission
and reception, filtering, preprocessing, and storage of CAN messages.
Under the effect of the powerful microcontroller, this card can
be made for one CAN controller manager without losing data, even
in systems with a high PCI bus load. Therefore, the CANopen critical
process can be implemented |
|
| |
directly by
CANopen firmware in the PISO-CPM100. In addition, users can develop
their CANopen application by using the CANopen library on the
host computer. When the PISO-CPM100 is active, the data exchange
between users’ application and CANopen firmware is performed via
the memory mapping method of the PISO-CPM100. |

The utility can save all the message that is received by PISO-CPM100 to a text file to help user to analyse the messages.
The software supports the user to configure the CANopen communication setting. And after configuring, user can save the setting into a cpm file for that user want to use the same setting next time.
The software utility can easily to access the I/O data of all the slave devices. The users can monitor the input data of the specific slave device and change the output data to the remote slave device with this utility.

Node 2： |
If user use the guarding function with PISO-CAN200/400 with CANopen library, the guard error event may be occured when the slave is more and the guarding time is shorter. This is because of that the accuracy of timer of windows is not enough. |
