Apologies for the late reply
This is the system architecture of the system. This is just a rough illustration, i think you get the idea:wink:
Are all three sites going through the one link?
-no, the new design is that the one remote site is connected to one monitoring site
How much I/O at each site?
**Is there a controller at each site? **
-yes, SNAP-PAC R2
What is each site talking back to? PAC Display? groov? Other?
-PAC Display Only. Getting all the data
Is the central site maned 24*7*365 or 'shutdown' overnight? (In other words, is the data flow continuous each day?)
-24/7 Operation, no shutdown.
Whats the poll rate of the master station to the remote site?
-1 second Poll rate
How many variables or I/O points is being requested?
-3 Analog, 10 DI, 1 DO, 1 Serial Comm
Are there any batch jobs run, like midnight backups, emails, FTP, receipe etc?
I tried to emulate the system and using Wire Shark to sniff the amount of Packets being transmitted.
I am Getting Around 20 Kbps of total Transmissions. I do not know if this is correct and i need to confirm the correct bandwidth consumption.
Hoping for your feedback.
