为了保证在任何时候系统都有高的完整性,TRICON-sis系统有如下特点: 有三重组合式冗余结构,三个完全相同的系统分支的每一个都能独 立地执行控制程序。且备有专用的硬件/软件机制,可对输入和输出进行"表决”。能耐受严酷的工业环境。能够现场安装,可以在控制器在线使用状态下进行模件一级的修理工作。I/O模件的更换不会打乱现场布线。能支持多达118个I/O模件(模拟的和数字的)和选装的通讯模件,该模件可以与Modbus主机和从属机连接, 或者和FoxboroHoneywell分布控制系统(DCS)、其它在Peer- to- Peer网络内的各个TRICON、以吸在802.3网络 上的外部主机相连接。 In order to ensure the highest integrity of the system at all times, the TRICON sis system has the following characteristics: There is a triple combined redundant structure, where each of the three identical system branches can independently execute the control program. And equipped with dedicated hardware/software mechanisms, Can 'vote' on inputs and outputs. Can withstand harsh industrial environments. Can be installed on-site and perform module level repair work while the controller is in online use. Replacement of I/O modules does not disrupt field wiring. Can support up to 118 I/O modules (analog and digital) and optional communication modules, which can be connected to Modbus hosts and slaves, or FoxboroHoneywell distributed control system (DCS) Other TRICONs within the Peer to Peer network are connected to external hosts attached to the 802.3 network.
