I heard that after downloading the MACS5 from Hamilton online, the settings in the controller are reset. Is this true?

Incremental downloading is not possible; however, if hardware needs to be added or a PID is required, the entire content must be downloaded and the system will be initialized. Generally, the configuration personnel at Riichi will set up some backup circuits and points, so that modifications can be made directly online when needed. It’s a bit annoying to use anyway, but the system is still quite useful.

This is still acceptable. Is the configuration of MACS5 convenient? Is it still a bit more troublesome compared to the configuration of Zhejiang University’s Zhongkong system?

Basically, this is the case with systems in China. In terms of ease of use, Zhongkong is slightly better than HoliTech; however, both Zhongkong and HoliTech have their own advantages in different industries – you should choose the system based on the industry you are in!

It’s not a problem with any particular system; some systems allow the settings to be saved in a file. For example, with Yokogawa’s CS3000, the settings can be imported after downloading it, thereby restoring the original settings

1. Does Zhejiang University Zhongkong still have advantages in the chemical industry? 2、Is the advantage still in the software? How should we understand the advantages of software? Is the light configuration simple on one hand? Are there any advantages such as stability (also heard from others)? What is software stability? 3. Is Hollyland’s hardware better than that of Zhejiang University Zhongkong? It seems that many people think so, but there are also different opinions. 4. Which is more suitable for the chemical industry, the JX-300XP or the MACS-F?

During the training provided by HollySys, several points were emphasized: hardware modifications, as well as changes to task configurations, will inevitably lead to a full reset of the system. Such a reset, of course, causes the controller to return to its initial settings, with all configurations being restored to their original state. However, incremental downloads cannot be used multiple times either; after too many incremental downloads (especially when made by different people), although it is indicated as an incremental download, it actually results in a full download. Not long ago, our facility experienced a single-system shutdown due to this! A lesson learned through blood – let’s share it here as a reminder to all! The control system of the central controller is slightly better in this regard compared to HILI; basically, unless the control scheme is modified, it won’t cause a full reset. This is especially true for the ECS-100X main controller from the central controller, with firmware version fw247 – I’ve used it, and no instances of a full reset have occurred even after making modifications. But one needs to be careful with the controller of FW243, as its functions are relatively weaker! Well, when it comes to downstream processing, foreign systems need to be more sophisticated; some of them can even handle individual modules or individual channels for downstream processing!

What is the name of the MACS V configuration software?

The JX-300XP is the earliest system developed by Zhongkong; it has a relatively small scale. It’s suitable for use in small systems, but it’s not very effective for larger systems! The hardware in the Allen-Bradley series is more or less similar; the MACS 5 is quite user-friendly. Its biggest advantage is that it doesn’t require a dongle – it’s possible to add additional operator stations as needed. It’s an excellent choice for companies that often need to change their design schemes, as there are no restrictions. Basically, the control systems in question are mainly used in the chemical industry, while those from Allen-Bradley are primarily used in the thermal power sector. However, this is merely how these companies position themselves in the market; their systems can be used in both industries, with the level of difficulty in implementing them varying. As for the hardware, the cards in the central control unit are relatively small and not fully sealed; the circuit boards are essentially exposed outside. Therefore, environments with highly corrosive gases need to be taken into consideration, as components that are exposed are not as reliable as those that are enclosed. Another point is that the 8 channels on the control unit’s circuit board are basically organized in groups of 4 channels each; there is no isolation between individual channels. Therefore, if no isolation elements such as safety barriers are used, and there is a problem with a signal coming from the field, it is very likely that this will affect the entire group of 4 channels on the same card or terminal board, resulting in increased costs and difficulties in maintenance

I added two new temperature points to my company’s DCS, but my modifications had no effect.
