产品详情资料
参数“仅显示”
通过输出放大器内的集成安全关闭关闭。如果不可能,则通过耦合模块(仅
H51q系统中)。相关中央单元的看门狗信号未关闭。这
参数仅允许达到SIL 1。
参数“正常操作”
与参数“仅显示”相同的反应,另外关闭
必要时连接中央单元。SIL 2要求参数化。正常和推荐参数。
参数“紧急关闭”
在输出模块出现故障时,关闭相关中央单元的看门狗信号,从而关闭输出放大器。
在输入模块出现故障时,看门狗信号不会关闭。
模块关闭
集成安全关闭的故障可测试输出模块将自动切换
至安全断电状态。
组关闭
如果有要求,可在用户程序中定义组关闭,以关闭所有属于故障模块组的可测试输出模块。
在用户程序内部,多可以通过以下方式将10个可测试输出模块分配给一个组
功能块H8-STA-3。
相关CPU的WD关闭
如果出现故障,相关中央模块的看门狗信号(WD)将关闭。
如果使用带有冗余中央模块和公共I/O总线的系统,则输出
模块与两个中央模块都相关。如果出现故障
中央模块已关闭。这意味着所有I/O模块已关闭(仅在
H41q-H/HS)。
如果使用带有冗余中央模块和冗余I/O总线的系统,则输出
模块与一个中央模块和一条I/O总线相关。如果出现故障,只有看门狗
相关中央模块的信号已关闭。这意味着仅相关I/O模块
关闭(仅在H41q HR/HRS时)。冗余中央模块仍在运行Parameter “Display only“
Switch-off by means of the integrated safety shutdown inside the output amplifier. If not possible then shutdown of the watchdog signal in the I/O rack by means of the coupling module (only
in systems H51q). No shutdown of the watchdog signal of the appertaining central unit. This
parameter is permissible only up to SIL 1.
Parameter “Normal operation“
Reaction as with parameter “Display only“, additionally switch-off of the watchdog signal of the
appertaining central unit if necessary. Parameterization required from SIL 2. Normal and recommended parameter.
Parameter “Emergency off“
Switch-off of the watchdog signal of the appertaining central unit and thus shutdown of the output amplifiers in case of a fault in the output module.
The watchdog signal is not switched off at faults in the input modules.
Module switch-off
A faulty testable output module with integrated safety shutdown will be switched automatically
to the safe de-energized status.
Group shutdown
If it is requested, a group shutdown may be defined in the user program in a way that all testable output modules appertaining to the group with the faulty module are also switched off.
Inside the user program up to 10 testable output modules can be assigned to one group by
means of the function block H8-STA-3.
WD switch-off of the appertaining CPU
In case of a fault the watchdog signal (WD) of the appertaining central module is switched off.
If systems with redundant central modules and a common I/O bus are used then the output
modules are related to both central modules. In case of a fault both the watchdog signals of
the central modules are switched off. That means all the I/O modules are switched off (only at
H41q-H/HS).
If systems with redundant central modules and redundant I/O bus are used then the output
modules are related to one central module and one I/O bus. In case of a fault only the watchdog
signal of the related central module is switched off. That means only the related I/O modules
are switched off (only at H41q-HR/HRS). The redundant central module is still in operation
