基于現(xiàn)場(chǎng)總線的FANUC 分布式控制
一問題的提出
1 問題的提出
1.1隨著網(wǎng)絡(luò)總線通訊技術(shù)的飛速發(fā)展，分布式控以其高可靠、易維護(hù)、布線施工簡(jiǎn)單等優(yōu)點(diǎn)，正在取代集中式控制。目前，流行的PROFIBUS 、CC-
FANUC對(duì)本公司的主站（NC系統(tǒng)）和從站（NC系統(tǒng)）用現(xiàn)場(chǎng)總線連網(wǎng)通訊有完整解決方案，無須用戶做太多工作。
但是，有些FANUC應(yīng)用系統(tǒng)的遠(yuǎn)程輸入/輸出（I/O）（如輔機(jī)、上下料物流滾道、冷卻系統(tǒng)、液壓）離FANUC NC系統(tǒng)距離太遠(yuǎn)。按傳統(tǒng)接入方法（1長距離拉線；2用光纜連接現(xiàn)場(chǎng)的IO
SIEMENS的ET200 PROFIBUS從站、OMRON的DEVICENET遠(yuǎn)程接入從站和三菱CC
2 問題的難點(diǎn)
第三方從站（SIEMENS ET200）接入到FANUC 主站是FANUC系統(tǒng)分布控制機(jī)加自動(dòng)線面臨的大挑戰(zhàn)。
FANUC系統(tǒng)對(duì)于總線通訊、總線接入從站采取市場(chǎng)化策略，只提供接口。在中國大陸流行的DEVICENET、PROFIBUS從站都可以用于FANUC主站系統(tǒng)上。用戶要采用分布式控制必須采用第三方產(chǎn)品，第三方產(chǎn)品和FANUC公司均不對(duì)對(duì)方產(chǎn)品提供技術(shù)服務(wù)，用戶要承擔(dān)無任何技術(shù)支持而失敗的巨大風(fēng)險(xiǎn)，所有工作由用戶自行負(fù)責(zé)完成。
DEVICENET、PROFIBUS從站接入FANUC主站是非常困難的。用戶須將從站的ESD或GSD相關(guān)參數(shù)輸入FANUC主站，F(xiàn)ANUC主站才識(shí)別有關(guān)從站。在沒有技術(shù)支持的條件下在含有數(shù)十萬數(shù)據(jù)的ESD或GSD文件中找到FANUC需要的相關(guān)參數(shù)，對(duì)于非總線研究的用戶來說是不可想象的，這是國內(nèi)非FANUC從站接入FANUC主站幾乎沒有先例的根本原因。
二 分布控制的方案
1 分布控制的方案
考慮到先進(jìn)性、可行性和我們目前的技術(shù)儲(chǔ)備，我們決定采用FANUC主站通過PROFIBUS連接FANUC從站+SIEMENS ET200從站的控制方案。參看圖1，F(xiàn)4-5、F1-2按狃站距主站太遠(yuǎn)，用ET200從站,單機(jī)電柜也有ET200從站，負(fù)責(zé)單機(jī)夾具IO。ET200從站直接由FANUC輸送主站控制。
SIEMENS ET200從站解決遠(yuǎn)程IO的接入和單機(jī)夾具IO接入，信號(hào)直接進(jìn)入FANUC主站，便于輸送的控制。FANUC從站和主站控制單機(jī)伺服軸和輸送伺服軸。
創(chuàng)新點(diǎn)和難點(diǎn)：SIEMENS ET200 PROFIBUS從站接入到FANUC PROFIBUS主站。
