Dear All,
I am doing our plants network upgrading works and have difficulty doing the design.
First please see the attached PDF files.
Basically, we have 2 plants in our Factory.
I named it Plant 1 & Plant 2.
Both plants were initially designed to be network of its own.
Due to the recent upgrading, more of the SCADA HMIs were introduced to both plants.
For Plant 1, we found that the HMI screens start to show "lagging" sympthom. I believe more control screens added with more I/Os and PLCs on the network would cause this to happen.
FYI, we are running on 100MBits networks unmanaged switches.
Please see attached PDF file - com. With more automation system upgraded, we tried to installed a remote station at Engineering offices to monitor the two plants PLC & HMIs. At the same time, the managing director requested to be able to view the HMIs in the office. We plan to link up both plants using fiber optics cable.
My first question:
By installing Gigabit unmanaged switches & Cat6 cables for Plant 1, will it improve on the data transfer? will this overcome "lagging" problem?
Second question:
Combining the both plants into single network may congest the two plants network. We are worry of this combination. We have to view both PLC and HMI from the single network due to budget constraint. Also we are not able to use internet switch for the time being. I was thinking of installing routers for combining the two plants. Will this avoid data congested issue?
I hope for some advices here.
Really hope to learn on network design.
Thanks & Regards,
Jason
