壓力下的表現

對於 James Cameron 來說使用現成的 SNAP PAC 系統控制深海挑戰者  潛水是有歷史意義的

2012 年 3 月 26 日，電影製片人，國家地理(National Geographic) James Cameron 駕駛單人的潛艇，在世界海洋的最深點潛水近 7 英里(11公里)。

Cameron's dive drew worldwide attention to the DEEPSEA CHALLENGE expedition, a joint scientific partnership by Cameron, National Geographic, and Rolex to research and explore the ocean's depths.

The sub's unique design and special materials are essential to withstand the extreme temperatures and pressures at full ocean depth, provide mobility, and keep the pilot safe.

But at the heart of the submersible, inside the 43-in. (109 cm) diameter pilot sphere, an off-the-shelf Opto 22 SNAP PAC System controls and monitors more than 180 onboard systems—including depth sensors, batteries, thrusters, life support, 3D cameras, and lighting.

Opto 22 SNAP PAC 系統在潛艇內

SNAP PAC 系統不斷地監視潛艇的狀態—例如電池的電力和氧氣的存量，將結果顯示在安裝在離駕駛員頭上只有幾英寸位置的一個彩色觸控螢幕上供駕駛員監視。此系統還讀取了駕駛員的操縱桿控制推進器推動和潛艇相對的位置，並控制機器手臂收集樣本和水下攝像機的焦距。

用在潛艇內 SNAP PAC 系統的產品與用在世界上各種各樣應用的產品，它們都是 Opto 22 同樣標準的產品。這個系統包含了一個 SNAP-PAC-S2 可程式自動化控制器，一個安裝 I/O 與智能模組的組裝基座等的I/O 處理單元，類比 I/O 模塊，序列通訊模塊，與高密度數位 I/O 模塊。PAC Project 專業版軟體組件被用來開發與執行控制與 HMI 應用軟體。

The SNAP-PAC-S2 controller was chosen primarily for its communications flexibility and speed. With its two independent Ethernet network interfaces and four individually configurable serial ports (RS-232, RS-485 2-wire or 4-wire), the PAC-S2 easily handles communication with the wide variety of devices and systems onboard.
