Protocol Block Overview; Profibus Network Configuration Tool - Honeywell Experion PKS User Manual

6 PROTOCOL BLOCK

6.1 Protocol Block overview

The Protocol Block represents one of the field network interfaces. The Protocol Blocks are automatically
created when a PGM block is created. These blocks manage the communication between the master (PGM) and
the slave devices. These blocks are also responsible for exchanging process, acyclic, and diagnostic data.
The Protocol Blocks are used to perform the field network configuration. The "Profibus Network Configuration
Tool "is the tool used to perform the PROFIBUS network and slave device configuration. This tool is also used
for online monitoring of the field devices. The "Profibus Network Configuration Tool " can be invoked directly
from the Protocol Block configuration tabs.
On creating a PGM block, two Protocol Blocks are automatically created and assigned to its parent PGM block.
You cannot create a Protocol Block individually. Similarly, you cannot delete a Protocol Block individually. You
must delete the parent PGM block to delete the Protocol Block.

6.1.1 "Profibus Network Configuration Tool "

The "Profibus Network Configuration Tool " is used for configuring the field network devices on the
PROFIBUS gateway. The Protocol Block configuration form is the host tool and the "Profibus Network
Configuration Tool " is an ActiveX component. The "Profibus Network Configuration Tool " can be invoked
directly from the Field Network Configuration tab of the Protocol Block configuration form. The "Profibus
Network Configuration Tool " frame contains the PGM as a master in the Network view. The Library view
contains the device catalog ("Profibus Network Configuration Tool " library) that lists all the available vendor
and PROFIBUS devices.
When you select a slave device, its associated Device Type Manager (DTM) also appears.
The following figure displays a sample Field Network Configuration tab of the Protocol Block that hosts the
"Profibus Network Configuration Tool ".
