AC800M Clustor card limitation
Can you please answer the Clustor limitation for AC800M - I/O's
1) How many number of cards possible in one clustor if all cards are redundant
2) If all cards are redudant/Single and all are Analog Output cards ,All channels are used, what will be impact on the cards - Any impact on the power requirement.
We have issue like this with 6 Reundant set of cards fully loaded no spare channel, is it possible for one clustor can handle the same.
You can max of 6red or 12 non redundant cards per cluster or 24non redundant or 12redundant cards per station if you use cluster extension. Even if you try to add 7th module in red cluster or 13th module in non red cluster it doesn't allow you to add. Only MTU will get change to use the full limitation for red and non red cards in both profibus/optical module bus You can ensure what protocol u r using to connect these modules bcos it adds some communication load on the controller. AFAIK i have used full load of cluster in both profibus/optical as well, aways tune the task accordingly to use the loops connected to make cyclic load <65%
