6712SR Refrigerated Sampler
Section 5 Extended Programming
5-40
When you enter each of the (up to three) phone numbers for the
sampler to call, if text messaging is active, a request for the TAP
(Telocator Alphanumeric Protocol) server number and communi-
cations parameters will be made.
As with voice messaging, the sampler will dial each telephone
number up to five times per alarm condition, until the message is
acknowledged.
5.20 Memory The 6712 Sampler contains 512 kilobytes of battery backed RAM
(Random Access Memory) that stores:
• Five sampling programs
• The sampling results from the most recent program
• The rainfall data collected from rain gauges
• The data from a refrigerator temperature sensor
• The data collected from a 700 Series module
• Parameter data collected from an SDI-12 Sonde
• Calculated flow information from the current flow
module
The sampling results memory stores up to approximately 1004
events (the actual number is dependent on the number of SDI-12
parameters). The program run and start time information is
logged as four events. These four entries are held for the duration
of the program. The remaining 1000 are for logging sample
events, program events, and errors from the currently running
program. If the running program exceeds 1000 events, the data
will “roll over.” That is, the sampler will replace the oldest stored
event with the newest event. When using an SDI-12 sonde, the
sampler logs additional entries at each sample event.
Module, sonde, refrigerator temperature, and rain gauge
readings are stored in memory partitions. The storage capacity
depends on the reading types, the number of bytes per reading,
and the data storage interval.
The sampler clears the sampling results memory when the site
description changes. It is important to collect the sampling
results before changing the site description – the data can not be
retrieved afterwards. Keep in mind that the description may
change when selecting an extended program.
The partition data is cleared when the sampler automatically
creates and sizes the memory partitions. This occurs when you:
• Select a new program with a different storage interval
• Change the Data Storage Interval in the current
program
• Change the programming mode
• Install a new 700 Series Module
• Change 700 Series Module mode of operation
• Add or remove a rain gauge with the Hardware Setup
• Add or remove a refrigerator temperature sensor as I/O3
