各位論壇高手
1.PLC網(wǎng)路通信模組必須使用Ethernet通信模組。
(The communication module of PLC is based on Ethernet.)
2.機臺設備系統(tǒng)須偵測所有Timing Chart的Timeout，且Timeout發(fā)生時，應產(chǎn)生對應的alarm。Timeout的值是可以在系統(tǒng)畫面上被修改的。
(Equipment should check all timeout. After the timeout is happened, equipment should report and show alarm. The value of all timeout must be configurable on the screen of equipment.)
3一般傳遞資料的通信，請先寫入Word后，至少延遲1秒再開始寫入Bit進行通信交握，確保資料正確。
(Normally, after writing Word type data to PLC, system of equipment needs delay 1.0 second at least then start doing handshaking with MES.)
4在完成交握后，PLC須將資料的值清除，格式為Binary者其值設為"FFFF"，格式為ASCII者其值設為"H20H20"
(After handshake finish, data is written in this timing chart shall be clear. Words of binary in memory shall be filled 0xFFFF and words of ASCII in memory shall be filled to space(&H20).)
4E Q PLC→MES的記憶體區(qū)塊，由EQ PLC在初始化時清除。
(EQ PLC→MES memory data shall be clear while equipment initialization.)
5 MES→EQ PLC的記憶體區(qū)塊，由MES在初始化時清除。
(MES→EQ PLC memory data shall be clear while MES initialization.)
這個是技術要求，哪位做個這類項目請留言，指導指導！！！能留點資料是最好的。。
大家多多交流！！！十分感謝....
