Notes:All the signal exchanges between BMS and DCS except signals specifically listed in corresponding document shall be through serial communication and are not included here. Ranges & Alarm values mentioned below are tentative & subject to revision after getting actual process dataAbbreviations used: LP means loop powered, SP means seperately powered.All flow signals shall be totalised (in DCS) and all Analog inputs shall be Trend displayed

Alarm

These signals are re-transmitted from BMS PLC, hardwired in 4-20mA format.

Analog inputs (4~20m DC) Close Loop

Indication, trend functions are required for all analog inputs, in general, though they are not specifically listed below. Only additional functions are specified below.Alarm values will be filled up later, once all the relevant info from vendors / process is available.
