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
Module is connected, and it is not full, address 1
will address that Storage Module regardless of
the address that is assigned to the Module.
Address 1 would be used with Instruction 96 if
several Storage Modules with different
addresses were connected to the CR510 and
were to be filled sequentially. The Storage
modules would be configured as fill and stop.
When the lowest addressed Module was full
data would be written to the next lowest
addressed Module, etc.
4.4.2 STORAGE MODULE USE WITH
INSTRUCTION 96
When output to the Storage Module is enabled
with Instruction 96, the Storage Module(s) may
be either left with the CR510 for on-line data
transfer and periodically exchanged, or brought
to the site for data transfer.
USE OF STORAGE MODULE TO PICK UP
DATA
The CR510 is capable of recognizing whether or
not the Storage Module is connected. Each time
Instruction 96 is executed and there is data to
output, the CR510 checks for the presence of a
Storage Module. If one is not present, the
CR510 does not attempt to output data. Instead,
the CR510 saves the data and continues its
other operations without advancing the Storage
Module Pointer (SPTR, Section 2.1).
When the user finally does connect the Storage
Module to the CR510, two things happen:
1. Immediately upon connection, a File Mark is
placed in the Storage Module Memory
following the last data stored (if a File Mark
wasn't the last data point already in storage).
2. During the next execution of Instruction 96,
the CR510 recognizes that the Storage
Module (SM) is present and outputs all data
between the SPTR and the DSP location.
The File Mark allows the operator to distinguish
blocks of data from different dataloggers or
from different visits to the field.
To be certain that the Storage Module has been
connected to the CR510 during an execution of
P96, the user can:
Leave the Storage Module connected for a time
period longer than an execution interval or
SECTION 4. EXTERNAL STORAGE PERIPHERALS
Use the SC90 9-Pin Serial Line Monitor. The
SC90 contains an LED which lights up during
data transmission. The user connects the SM
to the CR510 with the SC90 on the line and
waits for the LED to light. When the light goes
off, data transfer is complete and the SM can
be disconnected from the CR510.
4.4.3
8 DUMP TO STORAGE MODULE
In addition to the on-line data output procedures
described above, output to the Storage Module
can be manually initiated in the 8 Mode. The
procedure for setting up and transferring data is
as follows:
1. Connect both the CR10KD Keyboard/Display
(or terminal) and the Storage Module to the
CR510 using the SC12 cable. (For terminals,
an SC32A is needed. See Section 5 for
interfacing details.)
2. Key in the appropriate commands as listed
in Table 4.2-1.

9 MODE -- SM192/716 STORAGE
MODULE COMMANDS
The CSM1 does not support the 9 Mode Commands.
The 9 Mode is used to issue commands to the
SM192/716 Storage Module, through the CR510,
using the CR10KD or a terminal/computer. These
commands are like
Module and in some cases are directly analogous
to the CR510
Modes. Command 7 enters a
mode used to review stored data, and 8 is used to
transfer data between two Storage Modules
connected to the CR510. The operations with the
Storage Module are not directly analogous as may
be seen in Table 4.5-1 which lists the commands
(e.g., when reviewing data, #A advances to the
start of the next Output Array rather than to the
same element in the next array with the same ID).
When 9 is keyed, the CR510 responds: 09:01.
1 is the default address for the Storage Module
(Section 4.4.1). If you have more than 1 Storage
Module connected, enter the address of the
desired Storage Module. Address 1 will always
work if only one Module is connected. Key A and
the CR510 responds: 9N:00 Where N is the
address which was entered.
You may now enter any of the commands in
Table 4.5-1 (key in the command number and
enter with A). Most commands have at least one
response. Advance through the responses and
return to the *9 command state by keying A.
