The supplied data does not specify a deterministic Ethernet protocol, network cycle time, backplane communication velocity, or channel isolation rating. The Ethernet interface should therefore be treated according to the applicable PanelView Plus communication configuration rather than assigned an unspecified deterministic-network performance. Rockwell Automation identifies the 2711P-K4M20D as a keypad terminal with RS-232 and Ethernet connectivity.\u003c\/p\u003e\n\u003cp\u003eThe 18-30 VDC input is an external DC supply connection. At the stated maximum consumption of 25 W, the supplied specification identifies 1.0 A at 24 VDC as the corresponding operating current reference.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: What type of operator input does the 2711P-K4M20D provide?\u003cbr\u003eA: The terminal uses a physical keypad assembly containing numeric and navigation keys.
