4.4.2 COMMA DELINEATED ASCII
Comma Delineated ASCII strips all IDs, leading
zeros, unnecessary decimal points and trailing
zeros, and plus signs. Data points are separated
by commas. Arrays are separated by Carriage
Return Line Feed. Comma Delineated ASCII
requires approximately 6 bytes per data point.
Example:
1,234,1145,23.65,-12.26,625.9
1,234,1200,24.1,-10.98,650.3
4.5 STORAGE MODULE (SM192/716)
The Storage Module stores data in battery
backed RAM. Backup is provided by an
internal lithium battery. Operating power is
supplied by the CR10 over pin 1 of the 9-pin
connector. When power is applied to the
Storage Module, a File Mark is placed in the
data (if a File Mark is not the last data point
already in storage).
The File Mark separates data. For example, if
you retrieve data from one CR10, disconnect
the Storage Module and connect it to a second
CR10, a File Mark is automatically placed in the
data. This mark follows the data from the first
CR10 but precedes the data from the second.
The SM192 has 192K bytes of RAM storage; the
SM716 has 716K bytes. Both can be configured
as either ring or fill and stop memory.
4.5.1 STORAGE MODULE ADDRESSING
The capability of assigning different addresses to
Storage Modules allows 1) multiple (up to 8) Storage
Modules to be connected to the CR10 during on-line
output (Instruction 96), 2) different data to be output
to different Modules, and 3) transfer of data from a
Module that is left with the CR10 to a Module that is
hand carried to the site for data transfer (*9 Mode).
Storage Modules are assigned addresses (1-8) either
through the *9 Mode or through Telecommunications
(SM192/SM716 Manual). 1 is the default address
when the Storage Module is reset, and unless you are
using one of the features which require different
addresses you need not assign any other address.
Address 1 is also a universal address when
sending data or commands to a storage module
with Instruction 96, *8, or *9. When address 1
is entered in the *9 Mode (default) or in the
device code (71, Table 4.2-1) for Instruction 96
or the *8 Mode, The CR10 searches for the
Storage Module with the lowest address that is
not full (fill and stop configuration only) and
addresses it. In other words, if a single Storage
