产品详情资料
协处理器和通信模块故障
模块故障由前LED(接口LED或ERR LED)发出信号。相应的功能块通过系统变量通知用户程序。为了维护
必须立即更换H41q和H51q系统故障协处理器或通信模块的冗余。更换冗余系统中的故障模块(两个
中央模块)在系统运行期间,必须遵守以下程序:
1.拆卸中央模块固定螺钉。
2.必须拆下相关的中央模块。
3.拆下待更换模块的固定螺钉。
4.必须拆除有缺陷的协处理器模块或通信模块。
5.必须拔下所有接口电缆,包括冗余电缆。
6.在更换有缺陷模块的模块上,所有开关必须设置为
相同的位置。
7.必须插入所有接口电缆,包括冗余电缆。
8.必须插入交换机中的协处理器或通信模块。
9.固定更换模块的安装螺钉。
10.必须插入相关的中央模块。
11.固定中央模块的安装螺钉。
9.8.4模块维修
由于无法遵守本质安全和安全相关模块的法律规定,因此用户无法进行维修。
此外,维修需要特殊的测试程序。
因此,应将有缺陷的模块发送给HIMA进行维修,并附上简短的故障描述
在客户场所进行检查后。中央的故障描述
模块和输入输出模块应包含:
–模块ID号(总计),例如F 8650E模块:01.064894.022
–到目前为止需要修复的测量值,
–从错误状态视图进行详细的故障诊断(请参阅用户手册ELOP II和
用户手册ELOP II资源类型),如果是冗余PES,则诊断两者
应包括中央模块。
故障描述应包含到目前为止所采取的测量(检查电源
供应、更换模块)。
9.8.5 HIMA Servi公司 Faults in the Coprocessor and Communication Modules
Faults of the modules are signaled by front LEDs (interface LED or ERR LED). The corresponding function block informs the user program via system variables. In order to maintain
the redundancy of the H41q and H51q systems faulty coprocessor or communication modules have to be changed immediately. To change faulty modules in a redundant system (two
central modules) during operation of the system the following procedure must be observed:
1. Remove fixing screw of the central module.
2. The related central module has to be removed.
3. Remove fixing screw of the module to be changed.
4. The defective coprocessor module or communication module has to be removed.
5. All interface cables including cable for redundancy have to be unplugged.
6. On the module in exchange for the defective module all switches have to be set exactly to
the same positions.
7. All interface cables including cable for redundancy have to be plugged in.
8. The coprocessor or communication module in exchange has to be plugged in.
9. Fix the mounting screw of the changed module.
10.The related central module has to be plugged in.
11.Fix the mounting screw of the central module.
9.8.4 Repair of Modules
A repair by the user is not possible as the legal regulations for intrinsically safe and safety-related modules cannot be complied.
Additionally special testing programs are necessary for repairing.
Therefore defective modules should be sent to HIMA for repair with a short fault description
after they have been checked on the customer's premises. The fault description of central
modules and for input and output modules should contain:
– ID no. (total) of the module e.g. at a F 8650E module: 01.064894.022
– measurements to repair up till now,
– detailed fault diagnosis from error state view (refer to the user manual ELOP II and the
user manual ELOP II Resource Type), in case of redundant PES the diagnosis of both
central modules should be included.
The fault description should contain the measurements taken up till now (checking the power
supply, exchange of the module).
