12.4.6 Important notes for using the CVI module
In order to guarantee a trouble-free communication between the valve interface and the connected
CANopen nodes, please follow these notes during the start-up of BL67-1CVI:
1 When connecting the CANopen nodes to the CVI module, all regulations concerning the installation
of a CANopen network have to be considered, above all, the rules for terminating a CANopen net-
work.
If the CVI module is the first or the last node in the network, the terminating resistor has to be acti-
vated via a module parameter.
2 The BL67-system as well as the CANopen nodes have to be supplied meeting the demands for volt-
age supply.
3 Please set the CANopen station addresses at the nodes. The first node in the CANopen subnet
receives address "1".
4 Please set identical baud rates at the CVI module and each CANopen node. With different baud rate-
setting, the CVI module and the connected CANopen nodes can not communicate.
5 Please parameterize the connected CANopen nodes according to the application. Activate present
nodes and deactivate inactive nodes, activate/deactivate the guarding and set the length of in- and
output data for every active node.
6 If the LEDs of the CVI module and the CANopen nodes switch to green, the system runs without
problems.
