HSB控制策略
HSB控制策略具有以下特点：
▪ 在重新同步时，活动单元不会自动切换到主单元
▪ 输出数据传输中必须包括关键控制数据和所有冗余输出
▪ 从活动单元到备用单元的无碰撞切换本产品用于RX3i系统。其部件被视为开放式设备（带电用户可接近的电气部件），并且必须安装在最终外壳中，即：制造以提供安全。外壳至少应提供一定程度的固体防护小到12mm的物体（例如手指）。这相当于NEMA/UL 1型外壳或IEC60529 IP20提供至少2级污染环境的等级。有关安装RX3i机架系统的详细信息，请参阅PACSystems RX3i系统手册，GFK-2314。
危险区域的安装以下信息适用于带有危险区域UL标志或ATEX标志的产品：
爆炸性环境：1类2组ABCD
该设备为开放式设备，安装在适用于只有使用工具才能访问的环境。
适用于I类2类A、B、C和D组危险场所或非危险场所
警告-爆炸危险-替换部件可能会损害I类的适用性，第2部分。
警告-当处于危险位置时，在更换或接线前关闭电源模块。
警告-爆炸危险-只能在已知无危险的区域更换电池。
ATEX 2区该模块必须安装在符合EN60079-15认证的外壳中，用于IIC组2区防护等级为IP54。外壳只能使用工具打开。
Hot Standby CPU Redundancy Features
For details on the configuration and operation of a Hot Standby CPU redundancy system, refer to the PACSystems
Hot Standby CPU Redundancy User’s Manual, GFK-2308.
▪ Supports single and redundant Ethernet remote I/O LANs through Ethernet Network Interface Unit (ENIU)
modules
▪ Supports simplex and redundantly controlled PROFINET remote IO (requires firmware version 8.00 or later)
▪ Survives any one single point of failure
▪ Bumpless switching
o Synchronized CPUs
o One scan switching
o Transfer data size up to 2Mbytes; selected in CPU hardware configuration and in variable properties
▪ Supports two redundancy communications links
▪ Online repair of failed component
▪ Online programming
▪ Redundancy Memory Xchange Module
o Manual toggle switch for role switching, which transitions control from the active unit to the backup unit
o Redundancy status LEDs
▪ Application-initiated role switching to switch the active unit to backup status
▪ Redundancy status bits and message logging
▪ Memory error checking and correction (ECC) single bit correcting and multiple bit checking
▪ Background diagnostics
HSB Control Strategy
The HSB control strategy has the following characteristics:
▪ Active unit does not automatically switch to primary on resynchronization
▪ Critical control data plus all redundant outputs must be included in the output data transfer
▪ Bumpless switchover from active unit to backup unit This product is intended for use with the RX3i system. Its components are considered open equipment (having live
electrical parts that may be accessible to users) and must be installed in an ultimate enclosure that is
manufactured to provide safety. At a minimum, the enclosure shall provide a degree of protection against solid
objects as small as 12mm (fingers, for example). This equates to a NEMA/UL Type 1 enclosure or an IEC60529 IP20
rating providing at least a pollution degree 2 environment. For details about installing RX3i rack systems, refer to
PACSystems RX3i System Manual, GFK-2314.
Installation in Hazardous Areas
The following information is for products bearing the UL marking for Hazardous Areas or ATEX marking for
explosive atmospheres:
CLASS 1 DIVISION 2 GROUPS ABCD
This equipment is an open-type device and is meant to be installed in an enclosure suitable for the
environment that is only accessible with the use of a tool.
Suitable for use in Class I, Division 2, Groups A, B, C and D Hazardous Locations, or nonhazardous locations
only.
Warning – EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I,
DIVISION 2.
Warning – WHEN IN HAZARDOUS LOCATIONS, TURN OFF POWER BEFORE REPLACING OR WIRING
MODULES.
Warning – EXPLOSION HAZARD - BATTERIES MUST ONLY BE CHANGED IN AN AREA KNOWN TO BE NONHAZARDOUS.
ATEX Zone 2
This module must be mounted in an enclosure certified in accordance with EN60079-15 for use in Zone 2, Group IIC
and rated IP54. The enclosure shall only be able to be opened with the use of a tool.
