If the slave receives no node guard inquiry it assumes that the bus connection is broken or the 
master went down.

Settings

As presetting it applies tfor all slaves that no node guarding is carried out. Shall that node guar-

ding be activated for a slave, an entry "enable node guarding" has to be added to the current 
WINGATE configuration. The parameters "node ID", "guarding time" and "life time factor" are to 
be determined in every entry.

 

Settings to node guarding

The parameter node ID indicates the ID of the CANopen

®

 node on which the control is supposed 

to happen. With the guarding time the interval in which the the master calls on the slave to send 
its guarding answer is to be indicated in milliseconds. 
The life time factor states how often the answer of the slave may be missing before the master 
assumes a failure of the slave.
These settings are available from Gateway software-revision 1.1 on.

14.3.1.3 Displaying the node guarding states

The node guard mapping is used to represent the node guard states of the single slaves to the 
PROFIBUS. Always 8 slaves are represented in one byte; so exactly one bit of information is 
reserved for one. This information can be shown in any desired spot in the Profibus data of the 
Gateway. So they are shown in the input area of the PROFIBUS master for this Gateway.

 

Display of the node guarding information

Arrangement of the bits for the nodes 1- 8:

Node 1-8

Byte MSB ( bit 7)

...

LSB (bit 0)

SlavenNode ID 8

...

Slave node ID 1

If no node guard is activated for a slave, the slave went down or still no node guarding informa-
tion was exchanged, the corresponding bit for this slave is 0. The bit is 1, if node guarding was 
activated for this slave and the slave answered in the corresponding time period to the node 
guarding inquiries.
