CM - PROFIBUS V. 1.6
23.6.17
Example: For node 1 and 2 node guarding is activated. Slave 1 doesn not answer to the node
guarding and slave ID 2 works regularly. A mapping of information is entered into the PROFIBUS
in the 2nd byte.
Fieldbus data of the Gateway:

These settings are available from Gateway software-revision 1.1 on.
14.3.1.4 Emergency Messages
The gateway can received up to 10 Emergency messages of all those slaves, for which node
guarding was activated and writes them into a queue. Simultaneously an internal counter is rai-
sed which contains the number of received EMCY messages. The data of the current message-
sas well as the number of the received EMCY messages and the node ID of the sender of the
message can be shown in the fielbus output data of the gateway. With the control byte the next
message can be recalled. If the data of the EMCY message is shown in the bus data, the new
data in the PROFIBUS is already visible with the toggle of the data
.
Setting of the emergency messages
These settings are available from Gateway software-revision 1.1 on.
14.3.1.5 Gateway control byte
Some characteristics of the Gateway can be controlled by fieldbus data. For this the information
of the fieldbus has to be transmitted to the gateway, that means that the information has to be in
the input area of the gateway. Only if this information is shown from the fieldbus in the Gateway,
the data can be analysed by the Gateway.
