This guide describes how to build a Premium Hot Standby System. Users of PL7 Warm Standby Premium systems should note that significant differences exist between Unity and PL7 systems, and where important, this guide identifies those differences. Anyone who uses a Hot Standby system or needs fault-tolerant availability through redundancy in an automation system. You should have knowledge of programmable logic controllers PLCs. You should possess a working knowledge of the Unity Pro software. Note: Terminology This guide uses the following terminology.

Revision History Rev. Changes 1 Initial version. This part introduces the Premium Hot Standby System. Hot Standby Systems deliver high availability through redundancy. A hot standby PLC system consists of single or multi-rack configuration.

If the Primary controller fails, the Standby controller takes control within one scan. To determine if the Primary controller failed, note controller s status displayed in the Display block with indicator lamp. Primary and Standby states are switchable.

Therefore, if one of the two controllers is functioning as the Primary controller, the other must be in Standby mode.

Otherwise, the second controller is in the default mode, which is offline. The Primary and the Standby controllers communicate with each other constantly to monitor the functionality of the system. If the Primary controller fails, the state of the controllers is switched. If the Standby controller fails, the Primary controller continues to run without redundancy and acts as a stand alone system. The second system automatically becomes the Standby.

RUN: program execution states and Hot Standby mode. The Premium Hot Standby CPU uses an embedded coprocessor Copro to provide a dedicated communications link, which transfers data between the Primary and Standby controllers.

In this chapter you will find an overview of compatibilities, for a system that has already been installed, differences from a PL7 Warm Standby Premium system, and restrictions for the Premium Hot Standby Unity system.

The features that are not supported by the Premium HSBY PLC will not be converted errors signaled by the converter , but the rest of the application will be converted. These four reverse registers can be written by the application program first section of the Standby controller and are transferred at each scan to the Primary controller.

During the scan, there is a tight synchronization between the Primary and Standby. Using a Premium Hot Standby in a multitasking environment may cause data to change between scans.

Because in a multi-tasking system, events may occur asynchronously to the normal scan. Those events may happen at a faster rate, the same rate, or at a slower rate. The result is that data modified by these events can be changed during a transfer.

Ensure that you both analyze your system needs and account for problems that may arise if you use Fast. They are shared between the two PLCs. Failure to follow this instruction can result in injury or equipment damage.

These ConneXium products can be used in different Ethernet topology: tree, ring, An event can be lost if it occurs just before or during a switch over. The use of a FAST tasks driving dedicated outputs is not recommended. Some change of state on the outputs can be lost at switch over. The use of counting modules is not recommended. The Premium Hot Standby CPU uses an embedded coprocessor Copro to provide a dedicated communications link, which transfers data between the Primary and Standby controllers.

These ConneXium products can be used in different Ethernet topology: tree, ring, An event can be lost if it occurs just before or during a switch over. The use of a FAST tasks driving dedicated outputs is not recommended. Some change of state on the outputs can be lost at switch over.

The use of counting modules is not recommended. Depending on the frequency, a certain amount of pulses can be lost at switch over. The use of edges is not recommended. It is not possible to guarantee that they are taken into account during a switch over. This function overwrites the initial value of a module parameter that is stored in the program code area, this area being not transferred from the primary to the standby.

In case of switch over, the new Primary will restart with the Modbus mode rather than the Character mode. It is not possible to replace the initial values of the declared variables with a save attribute ,e. The use of DFB is not recommended in the first section. This chapter provides information about behavior and performances of a Premium Hot Standby System.

This chapter contains the following sections: Section Topic Page 3. This section describes the Behavior of the Premium Hot Standby system. One of the controllers PLC functions as the Primary controller and the other as a Standby controller. The Primary updates the Standby at the beginning of every scan.

The Primary and Standby communicate constantly monitoring the health of the system. If the Primary fails, the Standby takes control within one scan. Because data must be transferred from Primary to Standby, any Premium Hot Standby System always has a higher scan time than a comparable standalone system.

Note: System Overhead System overhead is the time required to copy the application data to the communication link layer. The network scan communication between Primary and Standby copros 1. This section describes the Performance of Premium Hot Standby system.

The following table shows the swap time for each of the Ethernet services. This chapter provides an overview of setting up, installing, and cabling a Premium Hot Standby System. Setting up a Premium Hot Standby System involves a number of processes, summarized in the following paragraphs here and explained in detail in other chapters of this document.

A Premium Hot Standby System requires two backplanes. Do not, in any case, connect other Ethernet devices on this link.
