注：这些模块的当前版本随附安装的绝缘子。这个在印刷线路组件的背面可以看到条带。RX7i机架随附一种绝缘体套件，包括足够的零件来更新三个90-70系列输入/输出模块，一个BEM713（总线发射器）模块和BEM731（Genius总线控制器）模块。
MMI301配置说明多次调用SVC_REQ57在一次扫描中可能导致CPU看门狗超时
多次调用SVC_REQ 57（逻辑驱动写入非易失性存储器）可能导致CPU使看门狗定时器跳闸并进入停止模式。数量调用SVC_REQ 57需要考虑许多变量：什么软件看门狗超时值是，正在写入的数据量、扫描是指非易失性存储（闪存）的年龄等。
GE Intelligent Platform建议将SVC_REQ 57的调用次数限制为一次每次扫描调用，以避免停止的可能性。SNP ID不总是提供与Series 90不同，PACSystems CPU的SNP ID不会出现在机器中版本编程器显示状态显示。服务请求11将始终返回零当没有SNP ID存储到CPU时。6.20版中的新以太网功能和增强功能在SNTP中，添加了对

Installation Manual, GFK-2223.
Insulating strips for high
voltage modules
An insulator strip is required on a high voltage module that is installed to the immediate
right of a module with a metal faceplate. Insulating strips should be installed on the
following modules that have versions earlier than:
IC697MDL240D IC697MDL640E
IC697MDL241D IC697MDL340G
IC697MDL250G IC697MDL341E
IC697MDL251E IC697MDL350F
Note: Current versions of these modules are shipped with the insulators installed. The
strip is visible on the back of the printed wiring assembly. The RX7i rack is shipped with
an Insulator Kit that includes enough parts to update three Series 90-70 I/O modules, a
BEM713 (Bus Transmitter) module, and a BEM731 (Genius Bus Controller) module.
Multiple calls to SVC_REQ
57 in a single sweep may
cause CPU watchdog
timeouts
Multiple calls to SVC_REQ 57 (Logic Driven Write to Nonvolatile Storage) could result in
the CPU tripping the watchdog timer and going to STOP-HALT mode. The number of
calls to SVC_REQ 57 that can be made requires consideration of many variables: what
the software watchdog timeout value is, how much data is being written, how long the
sweep is, age of nonvolatile storage (flash), etc.
GE Intelligent Platforms recommends limiting the number of calls to SVC_REQ 57 to one
call per sweep to avoid the potential of going to Stop-Halt.
SNP ID not always provided Unlike the Series 90, the PACSystems CPU’s SNP ID will not appear in the Machine
Edition programmer Show Status display. Service Request 11 will always return zeros
when no SNP ID has been stored to the CPU.
New Ethernet Features and Enhancements in Release 6.20
In SNTP, added support for
Local Time Zone & Day light saving time for all Modes of SNTP communications.
Time Synchronization using Unicast Mode.
New CPU Features and Enhancements in Release 6.75
