5.1 Connection
The connection can be made with device specific pin assignment which is enclosed
when the device is delivered.
For the supply shielded cables with twisted core pairs have to be used !
5.2 Switching on the supply voltage
After the connection and all settings have been carried out, the supply voltage can be
switched on.
After power on and finishing the initialization, the measuring system goes into the
PRE-OPERATIONAL state. This status is acknowledged by the Boot-Up message
“
COB-ID 0x700+Node ID
”. If the measuring system detects an internal error, an
emergency message with the error code will be transmitted (see chapter "Emergency
Message", page 57).
In the PRE-OPERATIONAL state first only a parameter setting about Service-Data-
Objects is possible. But it is possible to configure PDOs with the help of SDOs. If the
measuring system was transferred into the OPERATIONAL state, also a transmission
of PDOs is possible.
5.3 Setting the Node-ID and Baud rate by means of LSS services
5.3.1 Configuration of the Node-ID, sequence
Assumption:
-
LSS address unknown
-
only one LSS slave should be in the network
-
the Node-ID 12 dec. shall be adjusted
Procedure:
Perform service 04
Switch mode global protocol
,
Mode = 1, to switch the LSS slave into
Configuration Mode
.
Perform service 17
Configure Node-ID protocol
, Node-ID = 12.
--> Wait for acknowledgement and check successfully execution,
--> Error Code = 0.
Perform service 23
Store configuration protocol
.
--> Wait for acknowledgement and check successfully execution,
--> Error Code = 0.
Switch the supply voltage of the LSS slave OFF and then ON again. Now the
new configuration is activated.
