YATS32 SNTP服務(wù)器配置YATS32 SNTP服務(wù)器的用戶應(yīng)將服務(wù)器配置為廣播模式或多播模式，但并非兩者都適用。如果服務(wù)器配置為兩種模式，則將向PLC發(fā)送兩條時間消息同時或在短時間內(nèi)。以太網(wǎng)接口重啟后第一個PING響應(yīng)丟失在重新啟動以太網(wǎng)接口后，第一個對PING的響應(yīng)足夠大，需要更多未生成一個以上的IP數(shù)據(jù)包（1466字節(jié)或更大）。
KONGSBERG AUE-1108工控產(chǎn)品多次零周期EGD交換可能不會產(chǎn)生相似數(shù)量的樣本如果為零生產(chǎn)周期配置了多個EGD生產(chǎn)的交易所，則交易所可能會不會產(chǎn)生相似數(shù)量的樣本。由于多個交換時的調(diào)度方式如果計(jì)劃“盡快”，一些零周期交換可能會產(chǎn)生更多的樣本比其他人。EGD性能信息需要詳細(xì)EGD性能信息的用戶應(yīng)聯(lián)系其應(yīng)用工程師并詢問關(guān)于CPU374的EGD性能應(yīng)用說明。未過濾多播數(shù)據(jù)CPU374不通過以太網(wǎng)對多播數(shù)據(jù)進(jìn)行硬件過濾。這意味著無關(guān)網(wǎng)絡(luò)上的多播消息在CPU374 PLC上增加了額外的負(fù)載，并且可能會顯著增加降低性能。足夠的負(fù)載會導(dǎo)致CPU374重置其通信處理器。在SRTP連接打開時更改IP地址可能會生成日志事件當(dāng)CPU374的IP地址為改變。SRTP通道報(bào)告9690H或0190H狀態(tài)，并可能保持打開狀態(tài)，直到連接因客戶端超時而終止。重載可能會阻塞車站管理器
EGD或SRTP負(fù)荷過大可能會阻礙Station Manager的運(yùn)行。
EGD Performance Information
Users requiring detailed EGD performance information should contact their Application Engineer and ask
about the EGD Performance Application Note for the CPU374.
Multicast Data Not Filtered
The CPU374 does not do hardware filtering of multicast data over Ethernet. This means that extraneous
multicast messages on the network add an additional load on the CPU374 PLC, and may significantly
degrade performance. Sufficient load can cause the CPU374 to reset its communication processor.
Changing IP Address While SRTP Connection Open May Generate Log Events
SRTP connections established to the client are not terminated gracefully when the CPU374's IP address is
changed. SRTP channels report either a 9690H or 0190H status, and possibly remain open until the
connections are terminated as a result of client timeouts.
Heavy Load Can Block Station Manager
A heavy EGD or SRTP load can block Station Manager operation.
