机箱的现场接线有多种终端选项，包括外部终端面板(ETP）和扇形电缆。ETP是一种电无源印刷电路板Q，现场布线很容易连接到该电路板上。将输入信号从现场传递到输入模块，或将输出模块产生的信号直接传递到现场布线，从而允许在不干扰现场布线的情况下移除或更换输入或输出模块。当使用数字输入或数字输出模块时，扇形电缆是ETP的替代品。扇出式电缆的一端连接到Tricon背板，另一端提供50根扇出式引线，每条引线单独标记有与连接器信号匹配的引脚号。有关更多信息，请参阅Ticon v9-v10系统的现场终端指南。通信模块Ticon控制器可以与其他控制器和外部设备进行通信。通信模块实现串行和网络通信以及各种通信协议。主处理器通过通信总线向通信模块广播数据。通常每次扫描都会刷新数据;它的扫描时间永远不会超过两次。有关通信设置和协议的更多信息。

逻辑解算器（SLS1508）包含逻辑解决能力，并提供16个I/O通道的接口，可配置为离散输入、离散输出、模拟输入（HART）和HART双状态输出通道。逻辑解算器和接线板安装在8宽的托架上。逻辑解算器通过载波通过双通道、本地对等总线（SISnet）和远程对等环相互通信。本地逻辑解算器由相同的DeltaV控制器托管，远程逻辑解算器由不同的DeltaV控制器托管。逻辑解算器由24V DC电源供电，该电源与驱动DeltaV控制器和I/O的电源分开。

逻辑解算器安装在8宽载波上的奇数插槽（1,3,5,7）中。冗余逻辑解算器使用四个插槽。SISnet中继器将通信扩展到连接到一个DeltaV控制器的本地逻辑解算器之外，并通过光纤环形载波扩展器电缆将全局消息广播到远程逻辑解算器在8宽载波之间扩展本地总线电源和信号。本地对等总线扩展电缆在不同载波上的逻辑解算器之间扩展本地对等总线（SISnet）。带有终端的1宽载波在终载波处终止本地对等总线。

There are various termination options for on-site wiring of the chassis, including external termination panels (ETPs) and fan-shaped cables. ETP is an electrically passive printed circuit board Q that can be easily connected to for field wiring. Transfer the input signal from the field to the input module, or directly transmit the signal generated by the output module to the field wiring, allowing for the removal or replacement of the input or output module without disturbing the field wiring. When using digital input or digital output modules, fan-shaped cables are a substitute for ETP. One end of the fanout cable is connected to the Tricon backplane, and the other end provides 50 fanout leads, each with a separate pin number that matches the connector signal. For more information, please refer to the on-site terminal guide for the Ticon v9-v10 system. The communication module Ticon controller can communicate with other controllers and external devices. The communication module implements serial and network communication, as well as various communication protocols. The main processor broadcasts data to the communication module through the communication bus. Usually, the data is refreshed every time it is scanned; Its scanning time will never exceed twice. More information about communication settings and protocols.
SLS1508
The logic solver (SLS1508) includes logic solving capabilities and provides interfaces for 16 I/O channels, which can be configured as discrete input, discrete output, analog input (HART), and dual state output channels for HART. The logic solver and wiring board are installed on an 8-width bracket. The logic solver communicates with each other through a dual channel, local peer-to-peer bus (SISnet), and remote peer-to-peer ring through a carrier. The local logic solver is hosted by the same DeltaV controller, while the remote logic solver is hosted by different DeltaV controllers. The logic solver is powered by a 24V DC power supply, which is separate from the power supply driving the DeltaV controller and I/O.
SLS1508
The logic solver is installed in odd slots (1,3,5,7) on an 8-width carrier. The redundant logic solver uses four slots. The SISnet repeater extends communication beyond the local logic solver connected to a DeltaV controller, and broadcasts global messages to the remote logic solver through a fiber optic ring carrier extender cable to expand local bus power and signals between 8 wide carriers. The local peer-to-peer bus extension cable extends the local peer-to-peer bus (SISnet) between logical solvers on different carriers. A 1-width carrier with a terminal terminates the local peer-to-peer bus at the final carrier.
