Which side will open a connection, the target device or Ethernet-equipped module? (Active open or Passive open)

SP.SOCOPEN : Establishes a connection. (CPU module dedicated instruction)
SP.SOCRCV : Reads the data received. (Read at END processing) (CPU module dedicated instruction)
SP.SOCSND : Sends data. (CPU module dedicated instruction)
