Communications Isolation Notes
The isolation between the Modbus Port and BCM electronics
is functional isolation only. All connections to the Modbus
terminal shall meet PELV requirements.
The isolation between the PROFIBUS Port and BCM
electronics is functional isolation only. All connections to
the PROFIBUS Port terminal shall meet PELV requirements.
The isolation between the Ethernet Port and BCM
electronics is functional isolation only. All connections to the
Ethernet Port terminal shall meet SELV/PELV requirements.
