描述

CTI 2500-RBC 901E-2500-RBC远程底座控制器设计用于将其底座上的I/O置于发生涉及PLC的各种系统故障时的“安全状态”

处理器和通信电缆。I/O的安全状态取决于

FREEZE跳线（请参见设置通信丢失时的输出状态)。以下情况将导致输出进入安全状态:

1.当PLC出现致命错误时，所有远程底座都会进入安全状态。⒉当您在RIO-a单底座上拉动电缆时

3.当您发送三个软件重启命令(部分重启、完全重启、，加电重启)。所有远程基地进入安全状态。

4.当您对非双RIO-A配置的系统触发RIO-A诊断时。5.当您有一个已启用和配置的基础，然后禁用它。2500C-RBC-RS485远程底座控制器

1、DCS的选型设计调试

1.1系统和控制器的配置要重点考虑可靠性和负荷率(包括冗余度）指标。通讯负荷率必须控制在合理范围内，控制器的负荷率尽可能均衡，避免"高负荷°问题的发生。

1.2系统控制逻辑的分配，不宜过分集中在某个控制器上，主要控制器应采用冗余配置。

1.3电源设计必须合理可靠。注意电源设计的负荷率和电源的冗余配置方式，保证两路独立电源。

1.4注重DCS系统接口的可靠性，注意重要接口的接口方式和冗余度。

1.5 DCS系统接地按厂家要求执行，避免接地问题造成系统大面积故障。应注重考虑系统的抗千扰措施，IO通道应强调隔离措施。重视电缆质量与屏蔽，重要信号及控制使用计算机专用通讯屏蔽电缆。

1.6根据设备运行特点和各种工况下机组处理紧急故障的要求，配置操作员站和后备手操装置。紧急停机停炉按钮配置，应采用与DCS分开的单独操作回路。

1.7对于保护系统，采用多重化信号摄取法。合理使用闭锁条件，使信号回路具有逻辑判断能力。

1.8调试期间按照调试大纲、办法，对所有逻辑、回路、工况进行测试，确保各参数设詈正确合理。

Description

CTI 2500-RBC 901E-2500-RBC Remote Base Controller designed to put I/O on its base in a "safe state" in the event of various system failures involving PLCS

Processor and communication cable. The security status of I/O depends

FREEZE jumpers (see Setting Output Status when communication is lost). The following conditions will cause the output to enter a safe state:

1. When a fatal error occurs in the PLC, all remote bases will enter the safe state. ⒉ When you pull the cable on the RI-A single base

3. When you send three software restart commands (partial restart, full restart, power-on restart). All remote bases are secure.

4. When you trigger RI-A diagnosis for A system that is not configured with dual RI-A. 5. When you have an enabled and configured base, then disable it. 2500C-RBC-RS485 Remote Base controller

1, DCS selection, design and debugging

1.1 System and controller configuration should focus on reliability and load rate (including redundancy) indicators. The communication load rate must be controlled within a reasonable range, and the load rate of the controller should be balanced as far as possible to avoid the occurrence of "high load degree problems."

1.2 The distribution of system control logic should not be too concentrated on one controller, and the main controller should be configured in redundancy.

1.3 Power supply design must be reasonable and reliable. Pay attention to the load rate of the power supply design and the redundancy mode of the power supply to ensure that the two power supplies are independent.

1.4 Pay attention to the reliability of DCS system interfaces, and pay attention to the interface modes and redundancy of important interfaces.

1.5 Grounding the DCS system should be carried out according to the manufacturer's requirements to avoid large-scale system faults caused by grounding problems. The anti-interference measures of the system should be considered, and the isolation measures should be emphasized in the IO channel. Pay attention to cable quality and shielding, important signals and control use computer special communication shielding cable.

1.6 According to the operation characteristics of the equipment and the requirements of the unit to deal with emergency faults under various working conditions, the operator station and backup manual operation device are configured. The emergency shutdown button should be configured with a separate operating loop from the DCS.

1.7 For the protection system, the multiple signal uptake method is adopted. Reasonable use of blocking conditions, so that the signal loop has the ability of logical judgment.

1.8 During debugging, test all logic, loop and working conditions according to the debugging outline and methods to ensure that each parameter swearings are correct and reasonable.
