The CP703 is the enhanced-system model with 16 MB memory, while the CP701 is the basic-system model with 8 MB memory. The appropriate model depends on the installed system software.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the LED indicators on the CP703?\u003c\/p\u003e\n\u003cp\u003eA: The LEDs provide visual status indications for maintenance and operational checks. The exact meaning of each indicator should be verified against the applicable module documentation.\u003c\/p\u003e\n\u003cp\u003eQ: Does the CP703 support redundant CPU operation?\u003c\/p\u003e\n\u003cp\u003eA: Yokogawa documents a synchronous hot-standby CPU architecture for the CENTUM CS 1000. However, redundant operation requires an appropriately configured FCS with the necessary hardware. A single CP703 module does not independently establish a redundant configuration.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":69254136135922,"sku":"CP703","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/CP7032.jpg?v=1794192930","url":"https:\/\/www.petrospare.com\/products\/yokogawa-cp703-field-control-cpu-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
