MMI301配置說明多次調(diào)用SVC_REQ57在一次掃描中可能導(dǎo)致CPU看門狗超時(shí)
多次調(diào)用SVC_REQ 57（邏輯驅(qū)動(dòng)寫入非易失性存儲(chǔ)器）可能導(dǎo)致CPU使看門狗定時(shí)器跳閘并進(jìn)入停止模式。數(shù)量調(diào)用SVC_REQ 57需要考慮許多變量：什么軟件看門狗超時(shí)值是，正在寫入的數(shù)據(jù)量、掃描是指非易失性存儲(chǔ)（閃存）的年齡等。
GE Intelligent Platform建議將SVC_REQ 57的調(diào)用次數(shù)限制為一次每次掃描調(diào)用，以避免停止的可能性。SNP ID不總是提供與Series 90不同，PACSystems CPU的SNP ID不會(huì)出現(xiàn)在機(jī)器中版本編程器顯示狀態(tài)顯示。服務(wù)請(qǐng)求11將始終返回零當(dāng)沒有SNP ID存儲(chǔ)到CPU時(shí)。6.20版中的新以太網(wǎng)功能和增強(qiáng)功能在SNTP中，添加了對(duì)

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.
