About us
Introduction
The 140 NOP 850 00 module is installed on the local rack of a Quantum system. The module provides interfaces for IEC61850 communication.
Functionality
The main purpose of the 140 NOP 850 00 module is to provide connection with IEC61850 IED devices as well as device management software that utilizes the IEC61850 standard.
The 140 NOP 850 00 module is mounted on the local rack and supports communication as:
The 140 NOP 850 00 module also provides high network availability by supporting the RSTP protocol, router, and the Quantum Hot Standby functionality.
The maximum number of 140 NOP 850 00 modules that can be mounted on a local rack is determined by your choice of CPU. The maximum numbers of communication modules – including 140 NOP 850 00 modules – supported by Quantum CPUs are as follows:

NOTE: All CPUs require the use of firmware version 3.30, or higher.
NOTE:
  • The 140 NOP 850 00 transmits explicit messages over the backplane. To enhance communication performance, set the Maximum ControlExpert data exchanged by PLC Scan setting to its highest value.

External Ports
The 140 NOP 850 00 module has 4 external Ethernet ports, which support up to three IP addresses that can be configured in the Communication Settings → IP Setting tab.
Port
Description
ETH 1 (Service port)
The ETH 1 service port 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 Modbus explicit messages or via SNMP.
  • extended network: This mode supports a dedicated network for the 140 NOP 850 00 module.
NOTE:
  • If the device, which is connected to the ETH 1 service 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 ETH 1 service port.
  • In port mirroring mode, the ETH 1 service port acts like a read-only port. That is, you cannot access devices (ping, connect to Control Expert, etc.) through the ETH_1 service port.
To configure this port, refer to the Configuring the Service/Extend Port topic.
ETH 2
The ETH 2 port provides supports the following modes:
  • access port (default): In this mode, diagnostic information is provided via Modbus explicit messages or via SNMP.
  • extended network: This mode supports a dedicated network for the 140 NOP 850 00 module.
ETH 3 and ETH 4
These 2 copper ports provide:
  • connections for IEC61850 communications and other Ethernet services
  • star, loop, or mesh topology
  • support for RSTP
