UDD406A 3BHE041465P201 Analog card

Add the following to the bottom of Table 25-8:”Configuration Commands”: priorityDemand = -5.0 For firmware revisions 0H and later, “priorityDemand” is the target position used when the shutdown input is activated. The default value is selected so that upgraded modules are backward compatible. The user can set this value to an intermediate value in order to create his own scheme for handling of plant upsets.Your Tricon controller is critical to the continued safe operation of your plant. But the growing complexity and connectivity of modern DCS control systems, as well as their reliance on offthe-shelf PC and networking technology, bring with them the potential to disrupt the operation of the safety system due to excessive or improper network traffic. A multi-layered Defense in Depth strategy is necessary to isolate your Tricon from computer viruses, network device failures and human error.

The Triconex Tofino Firewall protects 

the Tricon Communications Module (TCM) from potential disruption due to abnormal or excessive network traffic. It permits only the specific types and rates of network communications that are required for correct system operation, and prevents all other types of network traffic from reaching the TCM. This provides an additional layer of protection to your Safety Instrumented System, further enhancing the overall safety and reliability of your facility. Any security events, e.g., blocked network traffic, detected by the Triconex Tofino Firewall are logged internally on the device and saved for later review by operations or security personnel.

Many control systems use Microsoft’s OPC (OLE for Process Control) technology.

 The Triconex Tofino Firewall protects the Tricon OPC server by tracking the OPC client data requests and dynamically opening only the minimum required ports in the Triconex Tofino Firewall to permit these data connections to pass through. All other unnecessary ports are blocked, resulting in significantly enhanced security for the Tricon OPC server. The Triconex Tofino Firewall is easy to install. Simply apply DC power and connect the device in-line in the network connection to the Triconex ommunications Module. The Triconex Tofino Firewall is pre-configured to work in most installations without changes. If the TCM has been configured to use nonstandard network ports, then the Triconex Tofino Firewall’s configuration may be easily modified to match the TCM configuration using the Triconex Tofino Firewall Configuration Utility
