HG G-98820ZA

English, Revision 09, Date: 13.12.2016

PDO_2 is transmitted with identifier 0x280 + node address. It contains 8 bytes accord-
ing to the following table.

The synchronous identifier is 0x80. It is possible to read out this parameter under index

[1005,00], but it is not possible to change it.

4.2.3.4.2

Heartbeat

The heartbeat mode is supported. Whenever a heartbeat time > 0 is set in the CAN

menu, the device status is transmitted under identifier (0x700 + node address) each

time the heartbeat timer has expired. The guard time is set to 0 afterwards.

4.2.3.4.3

Node Guarding

Whenever the Heartbeat time is set to 0, the device replies to a Remote Transmission

Request of the Identifier (0x700 + Node address) with the device status (refer to Table

14 above), while the highest bit changes. The device does not monitor the timely re-
ception of RTR Frames.

4.2.3.4.4

Description of the Service Data Objects (SDOs)

The service data opject is used to access to the object index. An SDO is always trans-
mitted with a confirmation, i. e. each reception of the message is acknowledged. The

identifiers for read and write access are:
