The 140NOC78100 control head module is installed on the local rack of a Quantum EIO system. The module provides the interfaces to communicate with a control network and client applications on an .
The main purpose of the 140NOC78100 head module is to provide transparency between the , the , and an , while preserving device network . In addition, the 140NOC78100 module also provides services to communicate with PLC applications running on the control network.
Only one 140NOC78100 module, which supports 1 Gbds can be configured on the local rack.
To communicate with remote I/O devices on a remote I/O network, interlink the 140NOC78100 module with the 140CRP31200 remote I/O head module (or a 140NOC78000 distributed I/O head module that is interlinked with the 140CRP31200 module) on the local rack.
To communicate with remote I/O or distributed I/O devices on the device network, interlink the 140NOC78100 module with the 140NOC78000 distributed I/O head module or the 140CRP31200.
To communicate with devices on an extended distributed I/O network, interlink the 140NOC78000 module with the extended port of the 140NOC78100 module.

NOTE: To help prevent dust from entering the unused Ethernet ports on this module, cover the port with the stopper:
The 140NOC78100 module monitors the functionality of network links depending on which links are connected to the network. The module has 4 external ports (up to three IP addresses).

The allows the diagnosis of Ethernet ports and provides access to external tools and devices (Control Expert, ConneXium Network Manager, HMI, etc.). The port supports these modes:
-
port mirroring: In this mode, data traffic from one or more of the 3 external ports – plus the internal port – is copied to this port. This allows a connected tool to monitor and analyze the port traffic.
-
access port (default): In this mode, diagnostic information is provided via EtherNet/IP or Modbus explicit messages, or via SNMP.
NOTE: In access port mode, the IP address of the port is the same as that of the control network.
-
extended network: In this mode, an existing distributed I/O network participates in the Ethernet remote I/O network when a 140NOC78000 distributed I/O head module is connected to the SERVICE/EXTEND port of the 140NOC78100 control head module and also connected to the INTERLINK port of the 140CRP31200 remote I/O head module.

disabled
NOTE:
-
If the device, which is connected to the SERVICE/EXTEND port, is configured for a speed that exceeds 100 Mbps, the Ethernet link may not be established between the device and the module through the SERVICE/EXTEND port.
-
In port mirroring mode, the SERVICE/EXTEND port acts like a read-only port. That is, you cannot access devices (ping, connect to Control Expert, etc.) through the SERVICE/EXTEND port.
