3BHB005171R0101控制系统模块
硬件应用程序FEC模块将来自现场设备的模拟和数字信号连接到MFP或MFC模块。IMFEC11模块可与Bailey Fischer&Porter FSK智能变送器和其他智能设备接口。IMFEC12用于常规变送器（BC、EQ和PT）和标准模拟输入。IMFEC11模块可以在两种模式之一下工作：FSK现场总线模式或FSK模拟点对点模式。在FSK现场总线模式下，单个双线输入（总线）最多可连接15个FSK智能变送器。所有输入（过程数据和模块到变送器的通信）均采用频移键控格式，并共享现场总线。有关现场总线通信的具体限制，请参阅NTFB01现场总线终端装置说明。使用此模式时，所有现场设备必须为Bailey Fischer&Porter。在FSK模拟点对点模式下，IMFEC11模块可以连接FSK智能设备的多达15个离散模拟过程输入，并与这些设备进行（数字）通信。此外，IMFEC11模块在该模式下工作时，可与传统变送器和其他外部模拟输入混合接口。这些设备只能向FEC模块输入过程数据；它们不能与模块通信。在点对点操作中，每个设备都单独连接到模拟输入终端单元或模块。
特征与所有INFI 90 OPEN模块一样，FEC模块的设计允许灵活创建流程管理系统。
该模块支持Bailey Fischer&Porter FSK数字智能变送器和其他智能设备、传统变送器和标准电压或电流输入。FSK数字能力（IMFEC11）消除了转换误差并提高了过程控制精度。始终可以访问实时进程状态。在现场总线模式下，所有信息（包括过程变量）在FEC模块和现场设备之间进行数字传输。FEC模块将过程数据、控制命令和变送器配置数据存储在存储器中。如果发生通信故障，它可以恢复与发射机的通信。恢复与故障变送器的通信后，FEC模块在控制模块（MFP/MFC）恢复更新过程控制之前检查变送器配置。说明内容本说明由八个部分和三个附录组成。简介概述FEC模块。它包含功能、说明、参考文件和规范。描述和操作说明模块操作的理论。安装包括操作注意事项、开关和跳线设置、安装和检查FEC输入。操作程序说明如何启动和操作FEC模块。故障排除描述如何从状态报告中监控变送器错误。它解释了如何检查FEC错误以及要采取的纠正措施。维护包含FEC模块的维护计划。
HARDWARE APPLICATION
The FEC module interfaces analog and digital signals from field devices to the MFP or MFC module. The IMFEC11 module can interface Bailey-Fischer & Porter FSK smart transmitters and other smart devices. The IMFEC12 is for use with conventional transmitters (BC, EQ and PT) and standard analog inputs. The IMFEC11 module can operate in one of two modes: FSK field bus mode or FSK analog point-to-point mode. In the FSK field bus mode, a single two-wire input (bus) links a maximum of 15 FSK smart transmitters. All inputs (process data and module to transmitter communication) are in the frequency shift keyed format and share the field bus. Refer to the NTFB01 Field Bus Termination Unit instruction for specific limitations on field bus communications. All field devices must be Bailey-Fischer & Porter when using this mode.In the FSK analog point-to-point mode, the IMFEC11 module can interface up to 15 discrete analog process inputs from FSK smart devices and communicate (digitally) with those devices. Additionally, the IMFEC11 module can interface a mixture of conventional transmitters and other external analog inputs while operating in this mode. These devices can input only process data to the FEC module; they cannot communicate to the module. In point-to-point operation, each device is individually wired to the analog input termination unit or module.
FEATURES
The design of the FEC module, as with all INFI 90 OPEN modules, allows for flexibility in creating a process management system. The module supports Bailey-Fischer & Porter FSK digital smart transmitters and other smart devices, conventional transmitters and standard voltage or current inputs. The FSK digital capability (IMFEC11) eliminates conversion errors and increases process control accuracy. Access is always available to the real time process status. In the field bus mode, all information (including the process variable) is transmitted digitally between the FEC module and the field devices. The FEC module stores process data, control commands and transmitter configuration data in memory. It works to restore communication with a transmitter if a communication failure occurs. Upon restoring communication with a failed transmitter, the FEC module checks the transmitter configuration before the control module (MFP/MFC) resumes updating the process control.
