Word 11: Relay Status Shows the current logical status of all relays. Applicaton Layer 0 = relay not asserted 1 = relay asserted “Asserted” indicates that the function controlling the relay is in an active state. Relay contacts can open or close based on this state, see your instrument manual for details. Word 12: Discrete Input Status Shows the current logical status of all discrete inputs. 0 = discrete input open 1 = discrete input closed Word 13: Multispan Selection Shows the currently selected span (1 to 4). Words 14, 15: PID 1 Setpoint Value Contains the current setpoint value for PID 1 in engineering units.
(See the Milltronics BW500 manual for a full description of this reading.) Words 16, 17: PID 2 Setpoint Value Contains the current setpoint value for PID 2 in engineering units. (See the Milltronics BW500 manual for a full description of this reading.) Words 18, 19: Batch Setpoint Value Contains the value of P564 – Batch Setpoint. (See the Milltronics BW500 manual for a full description of this parameter.) Words 20, 21: Batch Pre-Warn Setpoint Value Contains the value of P567 – Batch Pre-Warn Setpoint. (See the Milltronics BW500 manual for a full description of this parameter.) Words 22 to 24: Parameter Number / Primary Index / Secondary Index, SPA; words 27 to 29:
Decimal Place, Format, Read/Write flag These words contain the last values written to words 0 to 2 and words 5 to 7 of the Write area. They confirm that the parameter value has been written. These words are not updated until the value has been successfully transferred and stored in the Siemens Milltronics SmartLinx instrument.
