Configuration 55
3.2.8 FLDBUS Menu
The FLDBUS menu is shown only if a DeviceNet, Profibus, EtherNet/IP, or ControlNet option card is installed.
The SWAP parameter on the FLDBUS menu enables byte swapping by the iRite BusCommand handler rather than
requiring a SWP (SWAPBYTE) instruction in the PLC. Byte swapping is enabled by default for DeviceNet cards;
for all other fieldbus cards, byte swapping is disabled by default.
• BYTE swaps bytes within the word before transmission to the scanner
• WORD swaps words 1 and 2, 3 and 4, within a 4-word packet
• BOTH performs both operations, swapping bytes within a word and swapping words within the packet
• NONE disables swapping
The DATASIZE parameter sets the size of the BusCommand handler data transfers. The default value (8 bytes)
matches the default data size specified in the EDS and GSD files, and used by the standard discrete transfer
commands. DATASIZE can be set to any value from 2–128 bytes (1–64 words), but the value specified must match
the data size set for the PLC Scanner I/O data size.

SWAP NONE
BYTE
WORD
BOTH Specifies byte-swapping used for the fieldbus card. For DeviceNet cards, this parameter defaults to
BYTE; for all other cards the default value is NONE.
NOTE: In Version 3.08 firmware, this parameter supports values of YES (byte swapping) or NO.
Version 3.09 replaces YES with BYTE, NO with NONE, and adds the values WORD and BOTH.
DATASIZE 8
2-128 Specifies the data size, in bytes, that the BusCommand handler transfers. If this parameter is set to
a value other than the default (8 bytes), ensure that it matches the Scanner I/O data size specified
for the PLC.
3.2.9 VERS Menu
The VERS menu can be used to check the installed software version or, by using the Reset Config softkey, to restore
all configuration parameters to their factory default values. There are no parameters associated with the Version
menu: when selected, the indicator displays the installed software version number.

The Contacts softkey on the Version menu allows display of contact information (see “FEATURE Menu,
CONTACT Submenu” on page 48). If an iQUBE
2 scale is configured, a Diagnostics softkey also provides access to
iQUBE 2 diagnostic information.
