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。
3.3输入/输出电平
在子机架中,为输入/输出模块提供插槽1至13。任何安排
I/O模块类型是可能的。在具有冗余I/O总线的PES中,插槽1至7上的模块为
分配给一条I/O总线,8到13分配给二条I/O总线。
子架下面有一个集成的电缆槽。它配有一个插座,用于
标签,可以打开以方便接近电缆。
3.3.1 24 VDC供电和配电
对于24 VDC电源和配电,我们建议使用K 7212、K 7213、K 7214、K 7215
组件或保险丝分配器K 7915。
它们包括用于熔断多达18个带有电路的独立电源电路的所有部件
断路器。
K7212还配有去耦二极管和带监控继电器的滤波器
用于主电源。
此外,您还可以使用PS1000系列的电源(参见ELOP II CD)。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.
3.3 The Input/Output Level
In the subrack, slots 1 to 13 are provided for the input/output modules. Any arrangement of
I/O module types is possible. In PES with redundant I/O bus, the modules on slots 1 to 7 are
assigned to the first I/O bus and 8 to 13 to the second I/O bus.
There is an integrated cable tray under the subrack. It is equipped with a receptacle for the
label which can be flapped open to provide easy access to the cables.
3.3.1 24 VDC Supply and Distribution
For 24 VDC supply and distribution we recommend to use the K 7212, K 7213, K 7214, K 7215
subassemblies or fuse distributor K 7915.
They include all components for the fusing of up to 18 individual supply circuits with circuit
breakers.
The K 7212 is additionally equipped with decoupling diodes and filters with monitoring relays
for mains supply.
Additionally you could use also a power supply of the PS1000 series (see ELOP II CD).
