E Data Acquisition/Central Data
Logging
The following section describes commands used to configure features of the
Data Acquisition/Central Data Logging options. The software is called
SCADA.
E.1 Return To Normal (RTN) Calling
You may program the unit to place calls upon an input returning to its normal
state. This applies only to channels which have become acknowledged alarms.
Return to Normal (RTN) calls may be placed to people, to a SCADA Central
Station or to a Central Data Logger (CDL) printer.
u There are three modes of calling for RTN calls:
Mode 0 = Data only
Mode 1 = Voice only
Mode 2 = Data and Voice
Return-to-normal (RTN) calls on units NOT configured for SCADA or CDL
will always be mode 1, Voice only. RTN calls on SCADA or CDL configured
units may be mode 0, mode 1 or mode 2. If mode 1 is set on SCADA/CDL
units then data calls to the SCADA Central Computer or CDL printer will be
skipped. (See Appendix K for a discussion of the Return-to-Normal modes of
operation.)
u To program Return to Normal Calls, press:
981 V
Where V is one of the following:
l 0 = OFF - No return-to-normal calls will be made (Default is OFF)
l 1 = ON - Return-to-normal calls will be made for channels in the
ALARM, ACKNOWLEDGED state whose input returns to normal
(non-violation).
l 2 = used to manually reset all return to normal channel status -
does not affect the return-to-normal calling ON/OFF state above or
the calling modes below.
l 3 = Sets return-to-normal mode to mode 0 - makes return to
normal calls only in data mode to the SCADA Central Computer
or to Central Data Logger Printer Entering this parameter does not
affect the RTN ON/OFF state.
