Before a specific automatic processing controller is offline downloaded, equipment influenced by the automatic processing controller is isolated, so that the offline downloading of the automatic processing controller cannot drive the equipment to be misoperated, in addition, the initial states of controls with self-holding logic, such as a part of group control modules, a reset trigger, a setting value setting and the like in the automatic processing controller, are recorded, and the state change after the downloading is avoided. After the automatic processing controller is off-line downloaded and the CPU (Central processing unit) of the corresponding workstation is checked to work normally, state general investigation of setting value setting, reset triggers and grouped control modules is carried out, the control is restored to the initial state, and then the isolated equipment is restored step by step.

in the obtained equipment, for the equipment needing to be kept online, a professional and an instrument control responsible person are isolated together at the DCS wiring switching cabinet side in a manner of removing a DCS instruction line; for other devices, power down isolation is performed by professionals.
It should be noted that, during the off-line installation of the automatic process controller, all signals are reset, during this period, the corresponding devices cannot be monitored and operated, the time length is about 20 minutes, during the off-line installation, some driving signals may be shifted or triggered by default values, so as to drive the local devices to operate, especially for some devices provided with an emergency mode, during the reset of the automatic process controller, the DCS interface card and the automatic process controller lose communication to trigger the emergency mode, so as to cause the field devices to operate. Before the automatic processing controller needs to be downloaded offline, professionals confirm an equipment isolation list to stop operation and power off and implement isolation of equipment in the list during the period of downloading a window, and for the equipment needing to be kept online, the relevant professionals and instrument control responsible persons jointly implement isolation on the DCS wiring switch cabinet side in a manner of releasing a DCS instruction line.

in the obtained equipment, for the equipment needing to be kept on line, a professional and an instrument control responsible person jointly extract the preferred drive card to drive an output phoenix terminal for isolation; for other devices, power down isolation is performed by professionals.
It should be noted that, during the period of executing the off-line downloading of the automatic process controller, the automatic process controller is reset to cause the preferred driver card to lose communication with the nuclear island DCS control system, during which the corresponding equipment cannot monitor and operate, the time length is about 20 minutes, and for some equipment provided with an emergency mode, an emergency fault mode is triggered, an emergency fault instruction is output, and the corresponding equipment is operated to an emergency state. Before the automatic processing controller is downloaded and installed off line, professionals confirm an equipment isolation list, the equipment in the list is stopped running and powered off and isolated during the period of downloading and installing a window, and for the equipment needing to be maintained on line, the relative professionals and instrument control responsible persons jointly pull out the preferred driving card piece to drive the output phoenix terminal; when the command and the feedback are at the same terminal, other system equipment may be at the same terminal, and further analysis and confirmation are needed. Among them, the device isolation manifest driven by the preferred driver card includes system devices of models 1VVP3950VV, 1VVP4226VH, 1CFI1111MO, 1CFI1210PO, and the like.

And combing the signals to be analyzed, namely analyzing a list of inlet signals transmitted from the automatic processing controller to be downloaded to other automatic processing controllers, checking a system instrument control logic diagram by each professional system TS according to the signals, analyzing the influence of signal deflection on equipment and whether the equipment needs to be isolated, and acquiring an equipment isolation list. Specifically, the system instrumentation control logic diagram SDM5.7 analyzes the devices affected by the signal 1are1001cg. xv90 in the page where the signal 1are1001cg. xv90 is located, and determines whether isolation is needed, and the pages where the signal 1are1001cg. xv90 is located include 1ARE14D01 page, 1ARE15D03 page, 1ARE15D04 page, and 1ARE15D05 page.
After confirming the device isolation list, the following isolation measures are taken:
for signals entering other automatic processing controllers and having a forcing block at the downstream, forcing the signals to be current values before loading by an instrument control responsible person; signals entering other automatic process controllers downstream without forcing blocks are isolated from the devices affected by the signals. The equipment influenced by the signal is divided into equipment driven by a DCS interface card and equipment driven by a preferred drive card, the isolation mode of the equipment driven by the DCS interface card is the same as that of the equipment driven by the DCS interface card in the cabinet, and the isolation mode of the equipment driven by the preferred drive card is the same as that of the equipment driven by the preferred drive card in the cabinet, so detailed description is omitted.

The instrument control debugging organization carding needs to analyze a signal list of inlet signals transmitted from an automatic processing controller to be downloaded to other automatic processing controllers, each professional system responsible person checks logic according to the signals, analyzes the influence of signal deflection on equipment and whether the equipment needs to be isolated, and obtains an equipment isolation list, and the analysis method is similar to the analysis method of network signals. The obtained device isolation list is shown in table 1.
TABLE 1
After confirming the device isolation list, the following isolation measures are taken:
for signals having a forcing block in the downstream of other automatic processing controllers, the forcing signal is the current value before loading by an instrument control responsible person, as shown in fig. 2, the forcing block signal is forced, wherein VAL represents the current value, the forcing signal needs to select the SIM window to be ON, after the forcing is performed after the VAL is kept in the current state, the signal can be guaranteed to be forced to the current value by clicking "Store" → "Data OK".
Signals entering other automatic process controllers downstream without forcing blocks are isolated from the devices affected by the signals. The equipment influenced by the signal is divided into equipment driven by a DCS interface card and equipment driven by a preferred drive card, the isolation mode of the equipment driven by the DCS interface card is the same as that of the equipment driven by the DCS interface card in the cabinet, and the isolation mode of the equipment driven by the preferred drive card is the same as that of the equipment driven by the preferred drive card in the cabinet, so detailed description is omitted.
Further, in step S1, the control with self-holding logic includes a group control module, a reset trigger, and a setting value setting module.
It should be noted that, in the local cabinet, there are controls with self-holding logic, such as a group control module, a reset trigger, a setting value setting module, etc., which may be cleared and reset before and after installation, and the state changes before and after installation need to be verified, and the local cabinet is restored to the initial state after installation. According to a group control module in the automatic processing controller to be downloaded, a reset trigger and a setting value setting module list, an operation responsible person records the state of each group control module before and after downloading, and for the group control module with the state changed after the downloading is completed, if necessary, the operation responsible person sets the corresponding group control module to be in a state before the downloading.
