主要功能?用于與AC 800M通信的CEX總線接口?用于R（un）、F（ault）、通信錯誤、主（總線主）和雙（冗余）的LED指示燈?運行于32 MHz的摩托羅拉MCF5307微控制器?用于代碼的2 MB閃存?用于配置和動態(tài)數(shù)據(jù)的8 MB SDRAM，也用作TRICONEX 3504E和AC 800M之間的雙端口存儲器?CEX總線+24V電源和DC/DC轉(zhuǎn)換器到+5V、+3.3V和+2.5V的電源?用于讀取本地I/O塊的手持式監(jiān)視器端口?現(xiàn)場總線端接開關(guān)說明TRICONEX 3504E，圖78，將TRIO現(xiàn)場總線連接到控制器AC 800M。TRICONEX 3504E和AC 800M之間的連接是通過CEX總線完成的。單個TRICONEX 3504E可以將30個塊連接到單個TRIO LAN。AC 800M最多可以有四個單一的TRIO局域網(wǎng)。TRIO的最大I/O為1000個I/O點。在以下條件下，TRICONEX 3504E可用于冗余處理器模塊配置：a.如果TRICONEX 3504E與冗余PM866一起使用，則僅應(yīng)使用TK850 CEX總線延長電纜在PM866模塊之間進行互連。不得使用BC810。b.如果TRICONEX 3504E與其他冗余處理器模塊（PM861A/PM864A/PM865）一起使用，則BC810或TK850 CEX總線擴展電纜可用于兩個處理器模塊之間的互連。PM891處理器模塊不支持TRICONEX 3504E。
Key Features ? CEX-Bus interface for communication to AC 800M ? LED indicators for R(un), F(ault), Communication Error, Primary (Bus Master), and Dual (redundancy) ? Motorola MCF5307 Microcontroller running at 32 MHz ? 2 MByte Flash memory for code ? 8 MByte SDRAM for configuration and dynamic data, also used as Dual Port Memory between TRICONEX 3504E and AC 800M ? Power supply from the CEX bus +24V supply with DC/DC converters to +5V, +3.3V, and +2.5V ? Hand Held Monitor Port used for reading Local I/O Block ? Field bus termination switch Description TRICONEX 3504E, Figure 78, connects a TRIO Field Bus to the controller AC 800M. The connection between CTRICONEX 3504Eand AC 800M is done via the CEX-Bus. A single CTRICONEX 3504Ecan connect 30 blocks to a single TRIO LAN. AC 800M can have up to four single TRIO LANs. The maximum I/O with TRIO is 1000 I/O points. The CTRICONEX 3504Ecan be used in a redundant processor module configuration under the following conditions: a. If the CTRICONEX 3504Eis used with redundant PM866, only the TK850 CEX-bus extension cable shall be used for interconnection between the PM866 modules. The BC810 shall not be used. b. If the CTRICONEX 3504Eis used with other redundant processor modules (PM861A/PM864A/PM865), either BC810 or TK850 CEX-bus extension cable can be used for interconnection between the two processor modules. The CTRICONEX 3504Eis not supported with the PM891 processor module.
