1. Fault-tolerant Ethernet is the control network of PKS. FTE not only provides fault-tolerant features, but also provides fast network response and security for industrial Ethernet control applications.
FTE (Fault Tolerant Etherent) Fault-tolerant Ethernet is a single network with a redundant network structure, implemented through Honeywell's FTE driver and commercial network equipment.
FTE networks include redundant switches and cables.
Topology: Dual parallel tree networks connected at the top.
2. The cascade lines (cross links) between switches form a single network. Commercial network equipment refers to switches, dual-port single network cards or single-port dual network cards.

3. The system must consist of a controller, server, and operating station.
4. FTE network includes redundant switches and cables.
Tree network: The network formed by connecting to the A port on the A switch is called the A network (yellow tree). The network formed by connecting to port B on switch B is called network B (Green tree). Localhost receives the data node.
FLEX operating station (F station): process data and related alarms and events, as well as other data information, come directly from the server;
There are two connection methods for configuring ES-F: Fixed connection method (Static): Provides a permanent dedicated connection for a specific ES-F. Rotary connection method (Rotary): Provides an on-demand connection, suitable for when full-time operational access is not required.
Console operation station (C station): process data and related alarms and events come directly from the controller; other data information comes from the server;
Console Extension operating station (CE): process data and related alarms and events, as well as other data information, all information comes from station C.
7. A C300 controller has two IOLINKs. Each IOLINK supports up to 40 IO cards, and one controller supports up to 64 IO cards. Each set of C300 controller supports up to 64 IO Units (IOU). The C300 controller must be connected to the control firewall. The FTE address of the main controller of the C300 controller is set to an odd number, and the backup controller address is the address of the main controller + 1.
Control Firewall (CF9) Control firewall: It appears in pairs in the FTE network, 8+1 ports, of which there is a dedicated network port for upward connection to the switch, and the remaining 8 network ports can be connected to the controller.
Function: Refuse to accept all information that the controller does not need. If the communication speed slows down, the flow of unimportant information will be controlled.
8. The C300 controller consists of controller hardware and control software CEE (control execution environment), as shown in the figure:
