5.3.3 Analog Input Modules
I/O Modules
Process Data Architecture for EtherNet/IP
The output modules seize 8 Instances in Class (0x65).
And the output modules seize 8 Instances in Class (0x66).
The hardware of an analog input module has 16 bits of measured analog data
per channel and 8 bits of control/status. However, the coupler/controller with
EtherNet/IP does not have access to the 8 control/status bits. Therefore, the
coupler/controller with EtherNet/IP can only access the 16 bits of analog data
per channel, which are grouped as words and mapped in Intel format in the
Input Process Image.
When digital input modules are also present in the node, the analog input data
is always mapped into the Input Process Image in front of the digital data.
Each input channel seizes one Instance in the Analog Input Point Object
(Class 0x67).
1 Channel Analog Input Module
750-491, (and all variations)
The input modules represent 2x2 bytes and seize 2 Instances in Class (0x67).
