• Flexible installation

Base units can be shipped separately from the enclosure and installed into the enclosure at a suitable timing. This

allows a project to perform the acceptance test using the base unit at factory in parallel with field wiring work to the

enclosure at the customer site. And this minimizes the exposure of the base unit to the harsh environment such as

dust, water, and electromagnetic noise by keeping the base unit in the warehouse during field wiring work to the

enclosure.

• N-ESB / Optical ESB bus interface function

This function allows for communicating with the upper-level field control unit and N-IO node. It also allows for

communicating with the lower-level N-IO node.

Uplink:

Downlink:

1 port /N-ESB bus module (N-ESB bus or optical ESB bus)

1 port /N-ESB bus module (N-ESB bus or optical ESB bus)

• Splicing box

This is installed in the enclosure as standard. Connect the optical fiber cable of the optical ESB bus from outside to

the splicing box.

• House keeping (HK) function

Monitors the temperature in the enclosure, the system power and field power output.

• Maintenance function

The node interface unit (NIU) has a Micro-USB maintenance port for maintenance.

The setting of the node address is possible with a NIU Node Number Setting tool.

NIU Node Number Setting Tool is included in the CENTUM VP R6 software media.
