Types of Communications Areas
For EtherNet/IP communications, the following three communications areas are used in the PLC to perform
communications.
Areas Used for the Different Control Methods
*1 The response area (2) and output area (3) are assigned to continuous memory addresses or to a variable.
Command/response
communications (1) Command area This is the area to which you write control commands for
the Vision Sensor to execute.
(2) Response area This is the area to which the Vision Sensor writes the
results of control commands executed from the command
area.
Data output after mea-

data for measurements after an inspection is performed.
