ABB FSPS-21, User Manual

Page: 88 / 214

The properties and services of a PROFINET IO device are described in a GSD file written
in GSDML (General Station Description Markup Language). The GSD file describes the
device-specific modules and the method of assigning modules and sub-modules to predefined
slots and sub-slots. For more information, see section
Downloading the GSD file (page 126) .
PROFINET network settings
In PROFINET, network devices are identified with station names. The controller uses DCP
(Discovery and Configuration protocol) to find devices with configured names from the
network. Device with the given name responds with an Identity response which also contains
the current IP address of the device.
If the current IP address differs from the address in the hardware configuration of the
controller, the controller sets the device with a new IP address according to the configuration.
This IP is set as temporary, which means that after reboot of the device, the IP address will
be 0.0.0.0 as specified in the PROFINET standard.
The recommended IP setting for PROFINET is Static IP and address is 0.0.0.0. With this
setting, there is need to configure the IP in only one place (hardware configuration) and this
avoids any IP conflicts among the devices.
PROFINET IO in FSPS-21
When PROFINET IO is selected as the communication protocol, the FSPS-21 module can
employ the ABB Drives, Transparent 16 and Transparent 32 communication profiles or the
PROFIdrive profile. You can select the profile via FSPS-21 configuration parameter 02
Protocol/Profile. You can select the appropriate device access point (DAP) and functional
module with the tool as well.
• Slot 0 has sub-slots, and the DAP module attached to it represents the device itself.
The following sub-slots are available:
• sub-slot 0x0001 is DAP
• sub-slot 0x8000 is interface sub-module
• sub-slot 0x8001 is port 1
• sub-slot 0x8002 is port 2.
• Slot 1 and its sub-slots support other functional modules and sub-modules described
in the GSD file. The following sub-slots are available:
1. For PPO types
• sub-slot 0x0001 is the telegram
2. For Standard telegrams
• sub-slot 0x0001 is the Module Access point
• sub-slot 0x0002 is the telegram
• Slot 2 is used for PROFIsafe
• sub-slot 0x0001 is PROFIsafe telegram
The services provided by the FSPS-21 module
• Cyclic messaging
• Acyclic parameter access mechanism
• Identification & Maintenance functions (I&M)
