Information and Control Network [TC-net^TM 100]

The TC-net^TM 100 is an information and control network based on the Ethernet, a de-facto standard network, and is available for the message transmission with the use of the TCP/IP and the UDP/IP.

The TC-net^TM 100, maintaining the openness of the Ethernet, is ready to interconnect seamlessly between information and control, and further is capable to extend to the internet and/or the intranet.

The TC-net^TM 100 is an information and control network conforming to the IEC/PAS (Publicly Available Specification) 62406 Real-Time Ethernet TCnet (Time-critical Control Network) approved by the IEC.

The TC-net^TM 100 is based on the communication technology of the TCnet, which is one of the Real-Time Ethernet under standardization in the working group of the IEC/TC65/SC65C and is proposed by the Japan national committee.

Real-Time Ethernet TCnet

General

Fig 1. Network Hierarchy Diagram

As shown in Figure 1, the network of the Integrated Controller V Series is based on a hierarchical configuration.
TC-net^TM 100 realizes high-speed and real-time transmission between supervisory units, computers and controllers via the Information and control LANs indicated by dotted lines in Figure 1.
Features
- TC-net^TM 100 has the following features.
  - Openness
    This network for monitoring and control maintains the openness of the 100Mbps Ethernet and has the collision avoidance function and the definite time responsiveness.
  - Communication service
    The communication service includes the scan transmission which transmits control data periodically (cyclic broadcast reception/transmission) and the normal message transmission.
    - Scan transmission involves three speed modes, that is, high speed, medium speed and low speed, which can be allocated in accordance with the data update cycle, thus securing definite real-time responsiveness.
    - In message transmission, the network has realized the protocol compatibility between TOSDIC^TM-CIE 1200 and T3H, supported not only by TCP/UDP/IP but also by Toshiba Standard Protocol and PCMP.
    - Note: PCMP is abbreviated from Process Control Message Protocol.
  - High reliability
    Can construct a highly reliable system configuration through transmission path dualization. The transmission path can select either Optical or Electrical.
  - Network relay function (Scheduled)
    TC-net^TM 100 can relay message transmissions directly between TC-net^TM 100 or Ethernet and transmission modules of another system.
Securing control data synchronism
- A control system must meet the requirement for data synchronization between each node.
  The TC-net^TM 100 secures control data synchronization by scan data transmission with so-called common memory system. The scan data transmission, based on cyclic transmission, is available at any of three speeds (hight, medium, low) whitch may be selected ranging from 1 ms second minimum in units of 0.1 m second, an impossibility with the conventional Fast Ethernet. The TC-net^TM 100 is free of delays in control data transmission even in the case where a large volume of data, for example, of moving pictures, is transmitted.
  
  Fig. 2 Scan transmission
High-performance transmission
- The conventional Ethernet technology is subject to serious ill effect on the response time in the presence of a data collision, in the case of multiple broadcast communications at one time, on the transmission medium.
- The TC-net^TM 100 employs the DOMA (Deterministic Orderd Multiple Access) transmission scheduling, to eliminate data collision and ensure deterministic, high-response data transmission for wide variety of time-critical industrial applications.

Mounting configuration

Fig 6. Mounting Transmission Modules for Model 3000
- The model 3000 transmission module is mounted on the station bus slot of model 3000's controller basic base. Up to four transmission modules can be installed in the basic base (Figure 6).
Fig. 7 Mounting Transmission Cards for PCs
- The transmission card for PCs is installed in the PCI bus slot of the PC.
  The general-purpose Ethernet card is also installed for message transmission.
  The transmission card for PCs and the general-purpose Ethernet card are connected to each other via the attached twisted-pair cable. Up to two transmission cards can be installed in the PCI bus slot (Figure 7).
TOSLINE-8000 Gateway station

Fig. 8 TOSLINE-8000
- The TOSLINE-8000 Gateway station is the network interconnection device between the TOSLINE-8000 and the TC-net^TM 100.
  On the TOSLINE-8000 side, the SVC station and the local station which controls the input/output data from/to the field devices, are connected by using the fiber optic cable.
  On the other TC-net^TM 100 side, the TC-net^TM 100 stations such as the integrated controller V series with the TC-net^TM 100 model 3000 module and the personal computer with the TC-net^TM 100 PCI bus interface card, are connected by using the redundant fiber media. The TOSLINE-8000 Gateway station is restricted to intercommunicate the scan data between the TOSLINE-8000 and the TC-net^TM 100.
