Output (O->T) Assembly Object (Class 0x04, Instance 0x66)
The following is a mapping of I/O values for the standard Ethernet/IP® assembly object instance
0x66. These are values that are sent from the Ethernet/IP® client (typically a PLC) to the
Ethernet/IP® server (control unit). The first word in the map contains the run/idle bit (bit 0). The
run/idle bit controls write access to the control unit. When the run/idle bit is set to 0 the control
unit is set to idle mode. In idle mode, the Ethernet/IP® server will allow read only access to the
control unit. When the run/idle bit is set to 1 the control unit is set to run mode. In run mode, the
Ethernet/IP® server will allow both read and write access to the control unit. The run/idle control
is defined for communications purposes only and has no affect on any other normal
control/sensing/alarming operation of the control unit. The output assembly size is 7 (16 bit
words).
Data Types
Bool – 1 bit Boolean discrete data
Usint – 16 bit unsigned integer analog data
Sint – 16 bit signed analog data
Float – 32 bit signed floating point analog data
Floating point values are represented in IEEE format (32-bit) where the 1
st
register is the LOW
word and the 2
nd
register is the HIGH word.
