The identifier is 700h + Node ID and it contains the MT state of the NMT Slave.
It i
s activated when the parameter “Producer Heartbeat Time” (1017h) is bigger than 0.
5.9. Timestamp
The Timestamp-Object can be used for setting the time.
This protocol is a timestamp with a length of 6 Byte. It consists of the days since 1.
January 1984 and the milliseconds after midnight.
The default value of the identifier is 100h. It can be changed at the index 1012h. A
receipt for the timestamp is only possible in the state Pre-Operational and when the
MSB of the Object 1012h is 1.
5.10. Network Management
The state machine is implemented according DS-301. The CCM 01 supports the
following orders:
-
Start Remote Node
-
Stop Remote Node
-
Enter Pre-Operational
-
Reset Node
-
Reset Communication
5.11. EDS-file
For the CCM01 an electronic data sheet (EDS-file) is available. It contains a complete
description of the object dictionary and it serves for an easy integration in a CANopen
configuration tool.
5.12. Examples for CAN-communication
In this chapter there are some examples for controlling the CCM 01 via CAN. All
numbers are in hexadecimal representation.

Sensor calibration
The laser sensor is calibrated with ISO MTD according to ISO 11171 and is to delivered
with a calibration certificate.
12 months are the validity of the calibration certificate.
