Topics Relating To The Integration Of Field Devices On The Fieldbus - Siemens SIMATIC PCS 7 Configuration Manual

Configuration of the hardware (AS and I/O)
6.7 Integrating field devices
Variables which restrict the number of permissible devices per DP/PA link, with a redundant
and a non-redundant connection:
● Feeding current of the DP/PA coupler (110 mA EX or 1,000 mA non-EX)
● Current consumption of the field devices (typically 12 mA)
● Address range of the field devices (max. 244 bytes of I/O data, 5 bytes per analog value)
● Cycle time on the PROFIBUS PA (if specific customer requirements need to be met)
Information on configuring Y-Link and DP/PA Link can be found in the "SIMATIC Process
Control System PCS 7 Engineering System"

Topics relating to the integration of field devices on the fieldbus

Fieldbus connection
As well as the configuration of field devices in the process control system, the layout of
fieldbuses must be taken into consideration too. Detailed information on the following topics
can be found in the Industry Online Support:
● PROFIBUS DP (RS 485)
