Discuss the models of domestic DCS systems

The positioning of the ECS100 is ambiguous, as both the JX300XP and ECS700 can function as mid-range products. So the positioning overlaps, and it seems to have stopped production now. Hollyland currently has only one DCS, the MACS V6+ K series hardware.

Let me tell you more about the Hangzhou Youwen Automation UW500 and UW500S; I hope this can help you

For example, the limit on the number of points for JX300XP. Spares and similar items that are not supported by Windows 7 systems

I started with Allen-Bradley, with the SMARTPRO version first. That version is really annoying – it can easily cause control initialization issues or crashes of the main controller. One has to be extremely careful when downloading it; it can only be done while the system is stopped； After upgrading to M6, it feels like adding modules and implementing controls is quite straightforward; smooth flight is a bit more challenging, but overall it’s easy to get started, with no issues during installation

Has anyone used the Nanjing Keyuan NT6000?

Do they still supply that annoying version? Besides M6, are there also M3 and M9? Specific considerations for selection, such as hardware and software.

ABB’s current flagship system is the MACS6 K series hardware, which offers good integration. The hardware layout and the inclined arrangement of the Honeywell PKS system facilitate heat dissipation. The upper-level software and hardware configuration have been integrated into a single configuration software; the hardware configuration core is based on the software concept of German CODSYS, which is similar to the modular approach used in Siemens PLCs. The configuration software is relatively more complex and requires some effort to work with. SMART PRO is an obsolete product; its host computer and control program need to be configured separately, which is rather troublesome, and the system is not very stable. The Allen-Bradley K series products also come with specialized versions tailored for power plants; Allen-Bradley is strong in power plant control and has invested considerable effort in this area. Zhejiang University Zhongkong currently promotes the JX-300XP and ECS-700 models. The 300 model features a cage-style design, which gives it a relatively low-end appearance; it also has a limited number of input/output points per station and a small scale, and its stability is far inferior to that of the ECS-700. The 700 system is used relatively frequently in large domestic petrochemical industries. In particular, in recent years, for large-scale facilities in the petrochemical sector, it is generally a rule that only the ECS-700 system is allowed to be used, while the 300 system is not permitted. The configuration is simple and easy to get started with; it is not as good as HaliTech’s systems in terms of sequential control, but it performs better than HaliTech’s systems in the field of chemical process control. The systems from various manufacturers are suitable for small devices, but for large petrochemical plants, Zhejiang University’s Control Systems is generally more appropriate, while for power plants, LS Electric is more suitable.

The M4 that even Allen-Bradley’s own people are afraid of

Have you done any research on the prices of the Zhongkong 700 and HaliTech M6? For the 300 model, I have several units. They won’t provide me with a quote for the 700 model, but I’ve used two units of the HaliTech M6; I’ve been planning to try out the 700 model as well

The Allen-Bradley MACS 3 (also known as Smart Pro, with version mainly around V3.1.3) belongs to the FM series of hardware; the lower-level software used is ConMaker, while the upper-level software is Citect v5.42. The FM series of hardware has not been available for sale for 6 years now, and the MACS3 series software has not been available for sale for over 8 years. In the early stages, Hilscher’s MACS 5 was referred to as MACS V 1.0, 1.1, and 1.2. Later on, in order to distinguish it from the earlier versions MACS2 and MACS3, as well as from the already released MACS4, it was simply called MACS 5. The version is roughly 5.2.3 or 5.2.4; its lifecycle should have ended by now. MACS5 can use FM series hardware or SM series hardware. Of course, the mainstream approach is to use FM hardware in conjunction with the MACS5 platform. Large-scale units in thermal power plants generally use SM hardware in combination with MACS5. The lower-level system uses the OEM version of Codesys, while the upper-level system employs a platform developed independently by Hikvision. Hollyland’s MACS 4 – the lower-level component of MACS 4 is the AutoThink platform, which was developed independently based on 3S Company’s Codesys platform, while the upper-level component remains Citect V5.x. MACS 4 can be seen as a continuation and upgraded version of the lifecycle of MACS3. The hardware no longer supports the FM series. But “seems” also supports SM, KM. MACS4 was released after MACS5. MACS 6: MACS 6 was available from the time of MACS5; it was initially designed to work with the NM series of hardware used in nuclear power applications. Later, version 6 of MACS was upgraded, and a series of derivatives were created. It became available for general process control around MACS 6.5. The version of MACS 6 that most people see is 6.5.x. The hardware is mainly from the KM series, which is what people often refer to as the K series. Little K. The K series was released around the end of 2013 and widely promoted in 2014. Below is AutoThink. The superior option is the independently developed MACS 6.5 platform. This series is very mature and stable. It is currently the mainstream phase of the life cycle. Regarding Hollyland’s SIS. Currently, Allen-Bradley’s SIS and HIA Guard systems. The control engine is the secure version of Codesys. It has passed TUV certification and inspection. In principle, any open third-party HMI software can be used. However, for use by Allen-Bradley itself, there is a dedicated SIS software; in addition to the programming and configuration tools for SIS, this software usually also includes the upper-level monitoring software for MACS 6.5.x. Moreover, for many projects, the upper-level monitoring component is provided without additional cost; therefore, there is no need to look for pirated versions of WinCC or Intouch in order to connect them to Siemens’ SIS. Currently, F-series spare parts are still on sale, but they are quite expensive. S-series spare parts are still on sale; they are mainly used in thermal power plants, and they are quite expensive. The K series is relatively cheaper.
