PROFIBUS-DP Configuration
In order for the V7 drive with the V7 PROFIBUS-DP Option to operate in a PROFIBUS-DP networked system, the PROFIBUS-DP master
must be configured to recognize the V7 drive on the network. Typically, the master scan list is setup and modified with a PROFIBUS-DP
configuration utility, such as COM PROFIBUS from Siemens. The configuration utility is typically provided by the vendor supplying the
PROFIBUS-DP master.
The V7 drive is a slave device and requires a master PROFIBUS-DP scanner to communicate on a PRFIBUS-DP network. The V7 drive
configuration entered into the master scan list, via the configuration utility, must match exactly the configuration built into the V7
PROFIBUS-DP Option. The V7 drive has diagnostic LEDs to annunciate the state of the PROFIBUS-DP network.
‹ Correct GSD file is used.
The configuration utility uses the GSD file to set certain parameters, including the Identification Number, the number of Input and Output
words, the supported baud rates, etc. The GSD file is stored in the GSD sub-directory under the directory where COM PROFIBUS was
originally installed. The “Scan GSD Files” option under the “File” menu can be used to load the GSD file information in COM
PROFIBUS if it has not already loaded. In COM PROFIBUS, for example, the Station Type PROFIBUS INTER selects the V7
PROFIBUS-DP Option.
The filename of the current version of the GSD file, that is used for the V7 PROFIBUS-DP Option is, “YASK00CA.gsd”. This GSD file
can be found at
www.drives.com .
‹ Master Scan List Is Setup Correctly
Verify that the PROFIBUS-DP Master scan list is configured to send and receive the correct amount of data to each node on the
PROFIBUS-DP network and that the PROFIBUS-DP Master has the devices correctly mapped in memory. There are several PROFIBUS-
DP scanners on the market today. Some support the configuration tools mentioned above and some have their own configuration tools.
Refer to the manufacturer’s documentation for determining how to verify and program the scan list settings in the PROFIBUS-DP Master.
The size and type of information expected from the PROFIBUS-DP Master scanner must match exactly (per the GSD file) the device
configuration. Determine that the PROFIBUS-DP Master operational words to and from the PROFIBUS-DP device are mapped into the I/O
space of the PROFIBUS-DP Master. For each specific PROFIBUS-DP Master, this I/O mapping may be different. Consult the PROFIBUS-
DP Master documentation to insure correct I/O mapping.
‹ V7 PROFIBUS-DP Option Configuration
With PROFIBUS-DP INTER selected as the Station Type, three configuration selections will be displayed. Select the configuration
applicable to the particular application. Basic Data consists of 3 word I/Os message (3 input words and 3 output words). Extended Data 1
consists of 16 input words and 16 output words. Extended Data 2 consists of 6 input words and 6 output words.
„ The Basic Data configuration consists of 3 words of combined I/O. 3 input words and 3 output words. Refer to 3 Word I/O
Message section of Chapter 3 for a detailed description of the Basic Data configuration.
„ The Extended Data 1 configuration consists of 16 input words and 16 output words. Refer to 16 Word Input/Output Message
section of Chapter 3 for a detailed description of the Extended Data 1 configuration. This configuration is also used on those V7
PROFIBUS-DP Options that have an Option Name SI-P/V7 or Code Numbers prior to 73606-7110. The Option Name and Code
Number are located on the right side of the option.
„ The Extended Data 2 configuration consists of 6 input words and 6 output words. Refer to 6 Word Input/Output Message section
of Chapter 3 for a detailed description of the Extended Data 2 configuration. This configuration is also used on those V7
PROFIBUS-DP Options referred to as Profibus II.
