15.3.1 Direct connection to CPU
• Connected PLC
For direct connection to CPU (RS-232C), the HMI adapter is required. (Refer to the con-
nection example shown below.)
However, 416-1 and 416-2DP do not support some devices. (Refer to the next page.)
• Setting of PLC
Set the MPI address of the PLC connected to the GOT using the programming software
(STEP7) for the S7-300/400 Series PLC.
The MPI address of the HMI adapter is "1", and the maximum MPI address is "31". Accord-
ingly, make sure to set the MPI address of the PLC inside the range from 2 to 31.
• Setting of GOT
Set the connected PLC, the connection type and the station No. as shown below.
