作為核安全級(1E級)數(shù)據(jù)通信網(wǎng)絡(luò)，其模塊的硬/軟件必須是經(jīng)過核安全級(1E級)的鑒定，有過成熟應(yīng)用經(jīng)驗的產(chǎn)品。本文不做詳細描述。

非核安全級數(shù)據(jù)通信網(wǎng)絡(luò)將各個過程控制功能組相互連接后再與操作和信息管理網(wǎng)絡(luò)通訊。功能組的劃分主要考慮所完成的功能，兼顧采購合同的責任范圍，以減少設(shè)計接口，又便于調(diào)試維修。

公用通訊網(wǎng)主要將兩機組公共部分以及廠區(qū)少部分系統(tǒng)的信息與控制命令，分別與兩個機組的操作和信息管理網(wǎng)絡(luò)進行通訊。

TXP通訊網(wǎng)絡(luò)有兩種： “電廠總線”和“終端總線” 。兩種通訊網(wǎng)絡(luò)都是由若干OSM網(wǎng)絡(luò)交換機通過光纖連接組成的虛擬環(huán)網(wǎng)結(jié)構(gòu)。該總線結(jié)構(gòu)是通過使用SINEC H1 FO而建立起來的，基于IEEE 802.3標準。OSM是SINEC H1 FO網(wǎng)絡(luò)核心部件。整個網(wǎng)是以環(huán)狀結(jié)構(gòu)相連接的，并通過OSM模件中的開斷點實現(xiàn)環(huán)形結(jié)構(gòu)。當虛擬環(huán)網(wǎng)上所有部件均正常工作時，其中必有一塊OSM模件的電子開關(guān)是打開的(RM模式)，在開斷點上，來自兩個方向的信號受到監(jiān)視。當虛擬環(huán)網(wǎng)上有一部件工作不正常形成開路時，信號僅來自單方向，則可以認為是總線故障。在這種情況下，斷點將被關(guān)閉，該電子開關(guān)閉合形成新的形式的總線網(wǎng)并且與此相連的總線部件將被重新結(jié)合在通訊網(wǎng)絡(luò)之中，重建過程小于0.3秒，同時報警通知系統(tǒng)維護人員排除故障，實現(xiàn)了冗余總線的設(shè)計。
