extend feature automatically selects the optimum rate to allow adequate
recording time for the user’s own set of messages at the best possible sound
fidelity. See Section 4.2.1, “Verifying/Extending Recording Time,” and Section
4.3, “Record Your Messages.”
REMOTE CHANNEL OR RC A Verbatim I/O point whose value mirrors
the value at some network address. Each active RC is associated with one and
only one network address. The RC number can be viewed both as a ‘speed dial’
abbreviation for the lengthy network address and as a ‘virtual’ I/O point that
supports alarm criteria. Different RCs can refer to the same network address.
All data objects referenced by any RC are either 1 or 16 bits in length. 1-bit
objects are termed “discrete” or “digital” points. 16-bit objects are sometimes
termed “analog” points even though the data may actually be a discrete counter
or timer. The type of object is implicit in the RC’s network address. This is to
say, any RC can be either discrete or analog.
Analog RCs are NEVER scaled to engineering units within the Verbatim
Gateway. They can only have decimal integer values in the range 0 to 65535.
Any desired must be done within the PLCs program. Floating point, hexa-
decimal, and octal data formats are not supported.
REPEATS
The number of times a series of messages (including Station ID
message) is spoken when an alarm call is placed. As used here, this number
includes the first recital of the messages. For example, 3 repeats means 3 times
total, not 4. See Section 5.3, “Receiving Alarm Calls” and Section 6.1,
"Program Codes.”
RING ANSWER DELAY The number of rings required before the
Verbatim autodialer will answer an inquiry call. See Section 5.3, “Receiving
Alarm Calls,” and 6.1, “Program Codes.”
RTU (Remote Telemetry Unit) A monitoring device, interfaced to a
communications medium, whose mission is to communicate conditions at a
remote or inaccessible site. RTUs are usually polled by a central computer on
some schedule or interval. Additionally, RTUs may request polling to report
any exceptions such as alarms or other events which require the attention of the
central computer or its operators. When a Raco Verbatim autodialer is
configured with the asynchronous communications module it is known as an
RTU. The Verbatim RTU does not loose any of the basic features of the
Verbatim autodialer. In addition, the Verbatim RTU is capable of receiving
polling calls from the Raco SCADA Central Computer. Furthermore, alarms
may be communicated to the Raco SCADA Central Computer or to a Raco
Central Data Logger (CDL) printer.
