Correcting Faulty Operation Caused by Noise

When noise is thought to be the cause of a malfunction in the DeviceNet net-
work, the following measures may be effective.

Suspend the communications cable shielding wire without grounding it. This will
filter the noise that flows from the ground to the communications cable and will
filter the noise current that flows in the shielding wire.

Suspend the communications power supply without grounding it. This will also
filter the noise that flows from the communications power supply ground to the
communications cable or the noise current that flows in the shielding wire. The
switching power supply is usually connected to the case and the capacitor as
shown below. The FG terminal must be suspended and the control board for the
power supply itself must be insulated.

Sharing the Same Power Supply

Slave Units in the DeviceNet network can be classified into three types accord-
ing to how the power is supplied, as shown below. (The DeviceNet Interface Unit
is the middle type.)

Because the power supplies for the communications, internal circuit and I/O are
individually insulated as shown below, as a general rule each power supply
should be connected separately.
