8 Model 2700 Transmitter with PROFIBUS-PA
Startup
2.3 Setting the node address
The factory default setting for the node address is 126. To set the node address:
• With the display, choose
OFF-LINE MAINT > CONFG > ADDRESS PBUS.
• With ProLink II, choose
ProLink > Configuration > Device (Profibus) > Profibus Address.
• With a PROFIBUS host, use the change address function of the host.
2.4 Configuring the analog input function block channels
You can set each of the transmitter’s AI function blocks to measure one transducer block channel. The
AI blocks are set at the factory to a default setting that is adequate for most applications, but you can
change the assignment of the AI blocks to meet special needs.
The default channel configuration for each block is shown in Table 2-1.
The available transducer block channels are shown in Table 2-2.
