10.7 Evaluation/backup process times
With the MP85A process controller FASTpress, you can reliably monitor and
document virtually all processes in industrial production. The system can man
age up to 10 cycles per second (without backing up process data).
The maximum number of process cycles is largely dependent on:
S The number of process curve measurement points (adjustable)
S The number of evaluation criteria (tolerance windows)
S Whether process data are to be saved (OK only, NOK only, all)
S Whether several MP85A process controllers should be operated in a net
work (network load)
S The performance of the storage medium
You can determine some of these points via the PME Assistant or INDUSTRY
monitor program (“Setting evaluation parameters” and “Data backup” menus).
Data is transferred to the memory card at a speed of 2 to 8 kB per second,
depending on the size of the files being transferred. The total backup time
results consists of the process time and the backup time on the destination
computer.
Important
If the process data is saved via Ethernet, backup depends on the network load.
Take this into consideration if you have short process cycle times.
