警告
与第49页设备要求相关的注意事项：
如果在没有800xA操作员工作场所的情况下使用AC 800M HI，则SM810/SM811上的系统报警输出（O2）应连接到
外部报警装置，用于报警检测到的错误，参见物理I/O
用于第72页上的操作员和维护人员交互。这是
还建议在使用800xA操作员工作场所时：
实现多样化的报警路径。第49页
第61页与系统结构选择相关的注意事项：
本地内置电气模块总线不能用于配置
具有冗余AC 800M HI。第65页
冗余AC 800M HI处理器单元，需要冗余光纤集群调制解调器。第65页
在冗余AC 800M HI系统中，CEX总线应始终通过CEX总线互连单元BC810连接。参见第66页
第67页与工艺界面选择相关的注意事项：
如果AI880A的输入回路由外部供电，或存在以下风险：
存在向信号线施加24V的情况，应配备回路
在信号线中配备保险丝（额定值<=0.1A），以避免可能的过热
在故障情况下的分路棒。第68页
如果AI880A as DI的输入回路由外部供电，或存在其他风险
如果存在向信号线施加24V的情况，则应配备回路
在信号线中配备保险丝（额定值<=0.1A），以避免可能的过热
在故障情况下的分路棒。第6页
Warnings related to Operation Procedures on page 127:
The operation procedures shall emphasize the operator’s responsibility to
verify his operations by checking the Confirm Operation dialog. on page
128
If the HART routing functionality of AI880A is not restricted by the configuration settings of the module, the operation procedures shall include
restrictions for use of this function. on page 129
Warnings related to Maintenance Procedures on page 129:
In redundant DO880 configurations, faulty DO880 modules shall be
removed from the system within the repair time of 72 hours. on page 130
Online replacement (Hot Insert) of the SM811 will lead to a short stop of
the SIL3 applications. The stop time is limited by the configured FDRT. on
page 130

Safety Summary (continued)
Warnings related to Application Modifications on page 132:
To verify that no unintended changes to the SIS part of the system are
done, always examine the difference report before download, (see Difference Report on page 115). on page 132
Warnings related to Firmware Upgrade on page 132:
To ensure a safe Firmware Upgrade of a stopped AC 800M HI, the steps
described in Table 19. Firmware Upgrade Procedure on page 133 shall
be performed. on page 133
Before Online Upgrade is started, check that the “Online Upgrade Handover Limit” is set in accordance with the time demands of the process
under control. on page 134
Online Upgrade of an AC 800M HI is not allowed if any changes to the
controller configuration or application is made. on page 135
To ensure a safe Online Upgrade of firmware in a running AC 800M HI,
the sequence described in Table 20. Online Upgrade Procedure on page
136 shall be performed. on page 135

Safety Summary (continued)
SPECIFIC
CAUTIONS
Cautions related to Equipment Requirements on page 49:
If the AC 800M HI is used without an 800xA Operator Workplace, the system alarm output (O2) on the SM810/SM811 shall be connected to an
external alarm device in order to alarm detected errors, see Physical I/O
for Operator and Maintenance Personnel Interaction on page 72. This is
also recommended when using 800xA Operator Workplace in order to
achieve a diverse alarming path. on page 49
Cautions related to System Structure Selection on page 61:
The local built-in electrical ModuleBus cannot be used in configurations
with redundant AC 800M HI. on page 65
Redundant AC 800M HI processor units, require redundant optical Cluster Modems. on page 65
In redundant AC 800M HI systems, the CEX-Bus shall always be connected via the CEX-Bus Interconnection Unit, BC810. on page 66
Cautions related to Process Interface Selection on page 67:
If the input loops of AI880A are externally powered, or another risk of
applying 24V to the signal line is present, the loop should be equipped
with a fuse (rated <= 0.1A) in the signal line to avoid possible overheating
of the shunt stick during fault situations. on page 68
If the input loops of AI880A as DI are externally powered, or another risk
of applying 24V to the signal line is present, the loop should be equipped
with a fuse (rated <= 0.1A) in the signal line to avoid possible overheating
of the shunt stick during fault situations. on page 6
