VMIVME-2510B is designed to support data transfer in monitoring or non privileged short I/O memory spaces. A jumper is provided that allows the user to select any I/O access type.

VMIVME-2510B is factory configured (without jumper J1 installed) for responding to short monitoring I/O access. VMIVME-2510B is designed with two sets of board selection switches and decoding logic, providing efficient memory address mapping for CSR and I/O addresses. When configuring subsystems that require multiple boards, this feature allows users to map CSR and I/O addresses to consecutive memory locations.


The faults of DCS during the production process are unique to each brand of DCS, and their symptoms and handling are also different. However, they can be classified into three categories:

(1) system itself problems and faults, including design and installation defects, software and hardware faults, etc;

(2) Faults caused by human factors;

(3) DCS malfunction caused by external environmental issues in the system.

Examples of problems and faults in the DCS system are common, including design and installation defects, controller crashes, network disconnections, black screen in the operator station, network communication blockages, software defects, low system configuration, and system interface issues. Power and grounding issues.

The DCS power supply of a certain power plant is ABB Symphony III power supply, which was installed according to the grounding method of II power supply during infrastructure construction. After the unit is put into operation, there have been multiple DCS module failures, signal jumps, and hardware burns; During the construction period of a certain power plant, there was a problem with the production and installation of the DCS grounding grid.

After the operation of the DCS, there were periodic fluctuations in all temperature measurement points; A power plant’s control system on the turbine side failed due to loose power connections. Lesson learned: DCS does not have a good grounding system and reasonable cable shielding, which can easily cause problems such as interference, missignaling, and module damage. Therefore, the design and configuration of DCS power supply should be reasonable and have margin; DCS grounding should strictly comply with the technical requirements of the manufacturer (if there are no special instructions from the manufacturer, follow DL/T774 regulations).

System configuration issue: During the DCS transformation of a 200MW unit in a certain power plant, the calculation of system configuration load rate was inaccurate, and in order to reduce investment, the technical indicators were close to the allowable limit. During debugging, some controllers had a load rate exceeding 90%, and some had a soft manual response close to 1 minute. The problem was only resolved after adding new configurations. The controller (DPU or CPU) has malfunctioned.

The main CPU of the HIACS system F3S1 of a 300MW unit in a certain power plant has malfunctioned, and the slave CPU has failed to switch to the main control, making the equipment inoperable. Perform online replacement steps on the faulty CPU until the power outage, and successfully switch from the CPU to the main control CPU. After replacing the faulty CPU, the system is functioning normally.
