10.3 Control with FB 45 and Ident profile
This chapter describes a process connection using the FB45 or Ident profile (PIB_1KB,
PIB_16KB, PIB_32KB):
● With communication module
● Without communication module (Ident profile only)
For an overview of the usable communication modules, see Figure 10-1 Overview of
comm
unication modules, MV400 interfaces and function blocks (Page 233)
The fun
ctionality described in Functional description (Page 25) is provided by the FB45 and
Ident profile.
Note
Understanding of MOBY system architecture/MOBY commands required
To understand the following description, you require knowledge of:
• MOBY system architecture
• MOBY commands
• Ident profile system architecture and Ident profile commands.
You will find descriptions of the software in Industry online support
(http://support.automation.siemens.com/

10.3.1 Setting parameters of FB45
For a detailed description of the parameter assignment and commissioning of FB45, refer to
the relevant FB45 Function Manual (J31069-D0166-U001-A2-0018).
The following blocks are required in the S7 project:
● "MOBY FB" (FB45) with instance DB.
● "MOBY Param": Parameter data block occupied by UDT10 or UDT11 (English or
German). In the S7 sample program "MOBY FB45", this is DB45.
● "MOBY CMD": Command data block occupied by UDT20 or UDT21 (English or German).
In the S7 sample program "MOBY FB45", this is DB47.
● "Data DB": A data block for result or job data (command data area). In the S7 sample
program "MOBY FB45", this is DB48.
