Data Format (continued)
EtherNet/IP applications that use a non-generic EDS file have the parameters and data values
listed above defined as double integers. In these applications, the Binary_Output_Format Bit,
and the Binary_Input_Format Bit must both be set to “1”. The Data_Endian Bit must be reset
to “0”. The data will then be transferred as thirty-two bit signed integers in little endian format.
When using the Modbus-TCP protocol, use “signed 16-bit integer” as the data type when
using the multi-word format.
The range of values when using the multi-word format is -32,768,000 to 32,767,999. When
used in continuous rotation applications, such as control of a conveyor belt, it is possible to
overflow these values. When any of the three position values overflow, the value of the associ-
ated data words will become indeterminate. AMCI strongly suggests using the signed 32-bit
integer format for continuous rotation applications.
Command Bits Must Transition
This condition also applies when switching from Configuration Mode to Command Mode. If a bit is set in
Configuration Word 0 while in Configuration Mode and you switch to Command Mode with the same bit set,
the command will not occur because the bit must transition between writes to the unit.
Output Data Format
The following table shows the format of the output network data words when writing command data to the
SD17060E2 or SD31045E2.
Figure R7.1 Command Data Format
Commands are only accepted when the command bit makes a 0

1 transition. The
easiest way to do this is to write a value of zero into the Command Word 0 before
writing the next command.
