Specific Example Section 2-2
• Connecting I/O Unit Connecting Cable
To connect each pair of Units, connect I/O Unit interface communications
connector 2 on the Unit closer to the Communications Unit to I/O Unit in-
terface communications connector 1 on the Unit closer to the end Unit.
Note The connecting cable for the I/O Unit is shown below.
• Connecting Communications Unit and I/O Unit Power
Note Be sure to separate the communications power supply, the internal
power supply for the Communications Unit and the CPU Bus Unit,
and the power supplies for the I/O Units. If the same power supply is
used, malfunction due to noise may occur.
The capacity required for the Communications Unit internal power supply,
can be obtained using the following formula:
Communications Unit internal power supply current
= Communications Unit internal current consumption + Sum of I/O Unit In-
terface current consumption
