Data Organization

Data from the FT2A is updated into the Anybus IC every 300 ms. Data is
organized as a set of two 16 bit registers (32 bits) for data and one 16 bit
register for status. Table 2.1 defines the FT2A registers.

Control

One control register is used to reset the total and elapsed time. Data for that
register must be set to 0x02 to reset the total. Only a transition from a 0 to
2 will clear the total. Keeping that bit set will not continuously clear the total.
This register needs to be cleared after the reset operation.

Baud Rate - Profibus

The Module supports all standard baud-rates from 9600 bps to 12 Mbps,
according to the Profibus specification. The Anybus-IC PDP supports
automatic baud rate detection, which means that the actual baud rate is only
configured in the Profibus Master.

Configuration File - Profibus

A GSD configuration file is needed by the master and is available from the
HMS-Networks Website under the AnyBus-IC/Profibus selection.
An example of the file is included for reference as Attachment A.

Profibus Functions

The following functions are not supported with the Standard GSD-file:
User Parameter Data (Set_Prm).
Extended Diagnostic Data (Slave_Diag).

ID Number - Profibus

The Standard AnyBus-IC Profibus ID number is 1810h. This ID number is
related to the GSD file. If the AnyBus IC PDP is to be customized with other
functions or names, a new ID-number must be used (ordered from the
Profibus organization).

Manual IP Address Configuration

Set the rotary switch setting to any desired position except zero. The IP
address will be set to 192.168.0.x, where x is the setting on the 2 digits of the
rotary switches.

Automatic IP Address Configuration

Set the rotary switches to zero. The Anybus chip has been programmed for
DHCP.

The control register for Ethernet is at address zero.

The Anybus-IC offers many other ways to operate. See the Anybus-IC Design
Guide. Programming of the Anybus-IC can be accomplished by connecting
a PC with a terminal emulator to the P2 connector on the local display with a
special Fox adapter board. The Anybus document can be downloaded from the
web at the following link :

http://www.anybus.com/support/support.asp?PID=88&ProductType=Anybus-IC or a
quick Google search for Anybus-IC.

Configuring the FT2A Ethernet IP with a Fixed Address

Set rotary IP address switches located on the local display board to an address
(i.e. 2, sw1=2, sw2=0)
Cycle the power and connect a cross-over Ethernet cable to a PC.

12

Note: Some PC/laptops can use a straight cable as they detect and switch the
lines automatically.

i

Open the web browser and enter 192.168.0.2 for the address and press enter.
The HMS Configurator should now be displayed. If not, check the cable and the
switch settings. (Addresses other than 2 may be used).

• Enter the IP address, Subnet mask and the gateway address in the HMS
Configurator.

• Uncheck “DHCP Enable” box.

• Click on “Save Configuration”.

• Reset the rotary IP switch address to 0 (sw1=0, sw2=0).

• Cycle the power and connect a straight Ethernet cable to the network.

• Ping the device with the IP address entered to verify the communication

link.

Protecting Access to FT2A HMS Configurator for Ethernet IP

Access to the HMS Configurator can be protected by creating a file containing
user names and passwords and storing it in the FT2A Anybus root directory as
specified in section 6-2 of the HMS Anybus Ethernet manual (see note below
for manual downloads). The file can be created using Notepad or any other
text editor.

For example:
User1:1234

User2:5678

Using Windows Explorer or any FTP program, transfer the file that you just
created into the FT2A Anybus root directory (See section 4-2 of the HMS
Ethernet manual). First connect to the FT2A by opening Windows Explorer and
replace the address with “FTP://xxx.xxx.xxx.xxx (where x is the IP address) and
press return. Windows explorer should now show the content of the specified
FT2A Anybus directory. Highlight the file that was created and drag it into the
folder that has the IP address.

Slave Address

The Slave Address is set using the two BCD rotary switches. Address can be
set from 0 to 99, for the Profibus/Modbus TCP Ethernet and from 0 to 63 for
the DeviceNet. Power needs to be cycled before the settings take effect. Rotary
switch SW1 controls the low digit address, SW2 the high digit address (ie
SW1=5, SW2=6, Address=65).

Anybus Chip Programming

The Anybus chip (U2) is shipped pre-programmed. If an AnyBus-IC PDP is
used in a customer-specific implementation, the Profibus ID-number and the
GSD-file must be changed to match the new implementation. This can be
accomplished using a terminal emulator (like "Hyperterminal") through a serial
or USB interface to connector P2 (see Fig. 5.1). A special cable is available
from FOX. HyperTerminal communication parameters should be set to 9600
Baud, 8 Bits, 1 Stop bit. Refer to the Anybus documentation for programming.

Note: After changing parameters for the Anybus Chip from the local display
(i.e baudrate, bus type) the FT2A needs to have the power cycled OFF and
back ON twice before the changes can take effect.
