GRUNDIG NRP53 44206-870.00主控制器
多电源循环在极少数情况下，VDD100、VAL132或VME-1182A模块可能不会
在电源在很短的时间内重复循环后进行配置时间将生成IO模块丢失故障。
在极少数情况下，这也可能导致其他模块故障配置，而不会产生额外的模块故障丢失。
这些附加故障可能导致与以太网通信接口失败。
用户可以通过关闭电源从这些情况中恢复至少5秒钟，然后恢复电源。
这将提供足够的“关闭时间”，以确保所有模块都能正常通电。
固件期间模块未重置升级RX7i当前未重置系统中的任何其他模块固件升级后。这可能导致模块丢失故障正在为智能模块生成。
无法通过某些第三方串行卡
PACS系统串行端口不适用于某些第三方串行端口卡。
无效的COMMREQ状态不正确程序名称PACSystems的程序名始终为“LDPROG1”。
什么时候在访问%L的COMMREQ中使用了另一个程序名存储器，生成的错误为05D5，这是无效的块名称。停止和运行模式转换优先级PACSystems CPU接收在停止和运行之间切换的请求来自许多不同来源的运行模式。
这些包括（但不是限于）Proficy Machine Edition、HMI、用户应用程序和运行/停止开关。
由于模式有许多潜在来源更改请求，可以接收新模式更改请求而另一个已经在进行中。
发生这种情况时，CPU评估新模式的优先级正在进行模式更改的更改请求。
如果新的模式更改请求的优先级等于或高于该请求已经在进行中，CPU转换到新模式，而不是正在进行的那个。
但是，如果新模式更改请求具有优先级低于正在进行的，则新模式请求为丢弃，CPU完成模式更改进步扫描模式优先级为（从最高优先级到最低优先级列出）停止暂停、停止故障、停止和运行。
IO启用/禁用状态不是模式优先级评估的一部分。
例如，CPU处于RUN IO ENABLED（运行IO启用）模式，SVC_REQ执行13功能块，将CPU置于STOP IODISABLED（禁用）模式。
在转换到STOP IO DISABLED之前完成后，RUN/STOP开关从RUN IO ENABLED（运行IO启用）更改运行IO已禁用。
在这种情况下，CPU会忽略新的请求从RUN/STOP（运行/停止）开关转到RUN IO DISABLED（运行IO禁用）模式因为它已经在处理转到STOP IO的请求DISABLED（禁用）模式和STOP（停止）模式的优先级高于RUN（运行）模式
multiple power cycles
In rare instances, a VDD100, VAL132, or VME-1182A module may not configure after power has cycled repeatedly in a very brief period of time. A Loss of IO Module fault will be generated. In extremely rare instances, this may also cause other modules to fail to configure, without generating additional loss of module faults. These additional failures may cause communication with the Ethernet Interface to fail. The user can recover from either of these cases by turning off power for at least 5 seconds and then restoring power. This will provide sufficient "off-time" to ensure that all modules can power up properly. Modules not reset during firmware upgrades The RX7i currently does not reset any other modules in the system after a firmware upgrade. This may result in Loss of module faults being generated for smart modules. Unable to communicate through some third party serial cards PACS Systems serial ports do not work with some third party serial cards. Incorrect COMMREQ status for invalid program name The program name for PACSystems is always "LDPROG1". When another program name is used in a COMMREQ accessing %L memory, the error that is generated is a 05D5, which is an invalid block name.
STOP and RUN mode transition priority
The PACSystems CPU receives requests to change between stop and run mode from many different sources. These include (but are not limited to) Proficy Machine Edition, HMIs, the user application, and the RUN/STOP switch. Since there are many potential sources for a mode change request, it is possible to receive a new mode change request while another is already in progress. When this occurs, the CPU evaluates the priority of the new mode change request with the mode change that is in progress. If the new mode change request has an equal or higher priority than the one already in progress, the CPU transitions to the new mode instead of the one in progress. If, however, the new mode change request has a lower priority than the one in progress, the new mode request is discarded and the CPU completes the mode change that is in progress. The sweep mode priorities are (listed from highest to lowest priority) STOP HALT, STOP FAULT, STOP, and RUN. (Note: The IO ENABLED/DISABLED state is not part of the mode priority evaluation.) For example, a CPU is in RUN IO ENABLED mode and a SVC_REQ 13 function block is executed to place the CPU into STOP IO DISABLED mode. Before the transition to STOP IO DISABLED is completed, the RUN/STOP switch is changed from RUN IO ENABLED to RUN IO DISABLED. In this case, the CPU ignores the new request from the RUN/STOP switch to go to RUN IO DISABLED mode because it is already processing a request to go to STOP IO DISABLED mode and STOP mode has a higher priority than RUN mode.
