3.2 Hardware settings
A DIP-switch in the connection compartment of the Cerabar S controls allows the
write protection and simulation functions to be set via hardware.
The default settings of the switches are as follows:
WP OFF: write protection via hardware is disabled
SIM ON: simulation is enabled (= allowed in configuration tool).
Device identification
Foundation Fieldbus identifies the device by its identification code and automatically
allocates an appropriate field address. There is no separate hardware switch for this
purpose.
When the device has been integrated into the network, see Chapter 3.3, it appears as
follows in the bus tree:
E+H_CERABAR_S_XXXXXXXX
A click on the name reveals the device tag, device ID and node address. The device
ID is made up of the following components:
Device_ID = 452B481007-XXXXXXXX
whereby: 452B48 = ID code for Endress+Hauser
1007 = ID code for Cerabar S
XXXXXXXX = Device serial number, as printed on the name plate
A right-hand mouse click on the name opens up a menu from which the PD_TAG and
NODE_ADDRESS can be changed.
