با سلام خدمت اساتید بزرگوار

فرض کنیم سه CPU مستر داریم با نامهای M1/M2/M3

M1 رو به عنوان فرستنده در نظر بگیرید M2 گروه اول و M3 گروه دوم

همونطور که میدونید در قسمت NETPRO در سمت M1 دو کانکشن با LOCAL ID متفاوت ایجاد میشه که به ترتیب 0001A000 و 0002A000

اگر مستر M2 را به LOCAL ID 1تنظیم کنیم باید M2 را به 2 تنظیم کرد یا نیاز نیست؟ فقط از طریق LSAP این کار انجام میشود

من درست متوجه سوالتون نشدم

ولی فقط در اتصال unspecified وارد کردن LSAP بصورت دستی لازمه

اگر ارتباط بین دو PLCکه هر دو در پروژه هستند تنظیم LSAPبطور خودکار انجام میشه

سلام وقت بخیر

این تست را بنده با چهار S7-300 انجام دادم. در این تست لازم است Local ID هر گروه با مسترهای هم گروهی یکسان در نظر گرفته شود. حال اگر یک مستر به صورت مشترک در دو گروه قرار گیرد، طبیعتا نیاز به دو کانکشن دارد که باید یک کانکشن با Local ID گروه اول و کانکشن دیگر با Local ID گروه دوم ایجاد کنیم.

مهندس جان این ارتباط مستر به مستر باید SPECIFIED باشه

منظور من این هستش که تو گروه های متفاوت در پیکربندی MULTICAST باید ایدی هم متفاوت باشه یا تنها متفاوت بودن LSAP کافیه؟ در ضمن ما در پیکربندی مستر به مستر هم باید LSAP رو باید دستی تنظیم کنیم

درود بر شما

بله دقیقاً در پیکربندی Unicast Specified و Unicast Unspecified در هر دو باید LSAP به صورت دستی تنظیم شود.

همچنین در روش Multicast و در تستی که بنده انجام دادم، در هر گروه هم LSAP و هم Local ID باید یکسان باشند.
