CONNECTIONS
1.: OV (GND)
2.: + VS (+10 - +36 VDC) 3.: NC
4.: NC 5.: CAN-L
6.: CAN-H
NOTE:
Please make sure that the CANbus is terminated. The impedance measured between CAN-H and CAN-L must be 60 ohm that means the cable must be connected to a 120 ohm resistor on each ends of the bus line. Internally the tranducer is not terminated with the resistor of 120 ohm.
Do not confuse the signal lines of the CAN bus, otherwise communication with the transducer is impossible.

3.Network Management The device supports CANopen network
(NMT) |
management functionality NMT Slave (Minimum |
|
Boot Up). |
8. Restore default parameter
Every CANopen device contains an international Network Management server that communicates with an external NMT master. One device in a network, generally the host, may act as the NMT master.
Through NMT messages, each CANopen device’s network management server controls state changes within its built-in Communication
State Machine.
This is independent from each node’s operational state machine, which is device dependant and described in Control State
Machine.
It is important to distinguish a CANopen device’s operational state machine from its Communication State Machine.
CANopen sensors and I/O modules, for example, have completely different operational state machines than servo drives. The “Communication State Machine” in all CANopen devices, however, is identical as specified by the DS301.
NMT messages have the highest priority. The 5 NMT messages that control the Communication State Machine each contain 2 date bytes that identify the node number and a command to that node’s state machine.
Table 1 shows the 5 NMT messages surpported, and Table 2 shows the correct message for sending these messages.

4. Baud rate |
Node-ID can be configurable via SDO |
|
communication object =x20F2 and 020F3 (see |
|
communication examples at the end of this |
|
coument). |
|
The default Baud rate is 250kbit/s. |
Important Note:
Changing this parameter can disturb the network! Use the service only if one device is connected to the network!
5.Node-ID and resolution Node-ID can be configurable via SDO
communication object 0x20F0 and 0x20F1 (see communication examples at the end of this documentation).
The default Node-ID is 7F.
Important note:
Changing this parameter can disturb the network! Use the service only if one device is connected to the network!
6. Parameter settings |
All object dictionary parameters (object with |
|
marking PARA) can be saved in a special |
|
section of the internal EEPROM and secured by |
|
checksum calculation. |
|
The special LSS parameters (objects with |
|
marking LL-PARA), also part of the objec |
|
dictionary, will be also saved in a special |
|
section of the internal EEPROM and secured by |
|
checksum calculation. |
Due to the internal architecture of the microcontroller the parameter write cycles are limited to 100,000 cycles.
7. |
Restore default |
All object dictionary parameters (objects with |
|
parameters |
marking PARA) can be restored to factory default |
|
|
values via SDO communication (index 0x1011). |
|
|
|
8. Heartbeat |
The heartbeat mechanism for this device |
|
isestablished through cyclic transmission of |
|
the heartbeat message done by the heartbeat |
|
producer. |
|
One or more devices in the network are aware |
|
of this heartbeat message. If the herartbeat |
|
cycle fails from the heartbeat producer the local |
|
application on the heartbeat consumer will be |
|
informed about that event. |
|
Heartbeat Message |
The implementation of either guarding or heartbeat is mandatory.
The device supports Heartbeat Producer functionality.
The producer heartbeat time is defined in object 0x1017.

9 Error handling Principle
Emergency messages (EMCY) shall be triggered by internal errors on device and they are assigned the highest possible priority to ensure that they get access to the bus without delay (EMCY Producer). By default, the EMCY contains the error field with pre-defined error numbers and additional information.
Error Behavior (object 0x4000)
If a serious device failure is detected the object 0x4000 specifies, to which state the module shall be set:
0:Pre-operational
1:Mo state change (default)
2:Stopped
EMCY Message
The EMCY COB-ID is defined in object 0x1014. The EMCY message consists of 8 bytes. It contains an emergency error code, the contents of object 0x1001 and 5 byte of manufacturer specific
error code. The device uses only the 1st byte as manufacturer specific error code.

10.SDO communication and read/write commands
The device fulfils the SDO Server functionality. With Service Data Object (S.D.O.) the access to entries of a device Object Dictionary is provided. As these entries may contain data of arbitrary size and data typ SDOs can be used to transfer multiple data sets from a client to a server and vice versa.

Each access to object dictionary is checked by the slave for validity. Any write access to nonexistent objects, to read - only objects or with a non-corresponding data format are rejected and answered with a corresponding error message.
CMD determines the direction of data transfer and the size of the data object:
