S7-1200 PLC 型號(hào)是 6ES7 1215-1BG31-OXB0 做服務(wù)器
300PLC  做客戶機(jī)  型號(hào)是6ES7 312C-5BE03-0AA0  以太網(wǎng)模塊是  343-1EX11-0XE0
1、首先添加硬件CPU（兩臺(tái)）、在300PLC上面插入以太網(wǎng)模塊\ 在建立數(shù)據(jù)塊DB3\DB4\、打開(kāi)數(shù)據(jù)塊建立數(shù)組、在點(diǎn)擊硬件CPU屬性、在時(shí)間存儲(chǔ)器上打勾。 [attachment=129164] [attachment=129165] [attachment=129166] [attachment=129167] [attachment=129168] [attachment=129169]      
2、建立網(wǎng)絡(luò)鏈接、添加新網(wǎng)絡(luò)、建立通信伙伴及數(shù)據(jù) [attachment=129170] [attachment=129171] [attachment=129172]  
3、編寫程序
4、在線監(jiān)控調(diào)試
