Connection of an OP3 on the MPI interface

  • Entry
  • Associated product(s)

PROBLEM:
OP3 has a plug connector (male) on the MPI interface. How do you get to an MPI network using it?

ANSWER
The OP3 gets its power supply from the PLC. The cable is thus active. According to the DIN/VDE regulations "active" interfaces which provide current or voltage must be in the form of a socket connector (female).
This regulation must be observed.
An appropriate cable is supplied with the OP3. Should it be lost or damaged, you can order a new one.
Order number for this cable: 6ES7 705 - 0AA00 - 7BA0
