Is it necessary to shut down the system in order to use Modbus for reading device data in Zhejiang University’s ZHKong DCS configuration?
Thread Content
It is necessary to read some data from two data packets. One of the devices whose data packets cannot be stopped – is there any way to retrieve part of the data from that data packet without stopping the device?
I’m not quite sure; what do you mean? Are two devices communicating with DCS485 to carry out configuration changes? On our end, the ECS700 supports online downloading; we just made a few changes recently. However, any modifications carried risks associated with downloading, so it depends on how well you can handle such situations.
Thank you very much for your reply. The AdvanTrol-pro software from Zhejiang University’s Control Systems Department has a function for grouping and partitioning digital signal data; digital signals that use 485 communication need to be included in two separate data groups. What I want to know is whether, when configuring 485 communication, these signals must be downloaded into both data groups? Are there any risks associated with downloading it? {:3_65:}
Hmm, this is 300XP; I’m not very familiar with it
The lower garment is part of the overall configuration; it’s not a standalone offline garment, and thus there is a risk of AO taking action
