Monitoring - Siemens SINAMICS S120 Commissioning Manual

3.4.4.3

Monitoring

Introduction
SINAMICS supports the following two optional monitoring services to ensure the functionality
of CANopen network nodes:
● Heartbeat:
● Node guarding:
Steps
On the Monitoring tab, enter the required monitoring service (heartbeat or node guarding).
1. Select the Monitoring tab.
2. The default commissioning value for the Heartbeat monitoring mechanism can be
3. The default commissioning values for the node guarding monitoring mechanism could be
The CANopen interface is now parameterized. To load the project to the target system in
ONLINE mode, carry out the following steps.
In the case of an error in the CAN communication, e.g. too many message frame failures,
the fault F08700 is reported (for details see List Manual S120). The fault is displayed in
parameter r0949. The reaction of the drive to the fault is set with p8641. The reaction of the
CAN node is set with p8609.
Note
Parameters p8609 and p8641 govern the behavior of the drive/CAN node in the event of a
CAN communication error or device malfunction.
The factory settings for the parameters are
p8609 = 1, => no change
p8641 = 0, => no response

3.4 Configuring the drive unit using the STARTER commissioning tool
SINAMICS (producer) cyclically transmits (heartbeat time) its communication status on
the CAN bus to the master application.
SINAMICS waits a certain time (node lifetime) for message frames from the master
application and permits a specific number (lifetime factor) of failures within a specified
time interval (node guard time).
The node lifetime is calculated by multiplying the node guard time by the lifetime factor.
Note
Only one node monitoring service can be activated at any one time (either heartbeat or
node guarding).
If both monitoring services are activated, node guarding is effective.
specified as 100 ms . Enter this value (unless it has already been entered).
– Time interval (guard time) 100 ms,
– Number of failures (lifetime factor) 3.
Enter these values (unless they have already been entered).
