CompoNet Remote I/O Communications
• Communications Error with Sensor Amplifier Unit:
This flag turns ON when the registered number of connected Sensors does not match
the number of Sensors available for communications, or when communications with a
Sensor Amplifier Unit fails after a connection with the Sensor Amplifier Unit has been
established.
■
I/O Mode 2
This mode uses the I/O area to check the Sensor Amplifier Unit’s detection level and
change settings.
This enables you to change Sensor Amplifier Unit settings even when connected to a
master that does not support explicit messages.
In this mode, you can connect a maximum of 16 Sensor Amplifier Units.
The I/O area that is allocated in the master consists of six input words and six output
words.
Input: Word m
Input: Word m + 1
