SECTION 4. EXTERNAL STORAGE PERIPHERALS

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 CR10 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.

4.5.2STORAGE MODULE USE WITH INSTRUCTION 96

When output to the Storage Module is enabled with Instruction 96, the Storage Module(s) (see

4.5.1for addressing on multiple modules) may be either left with the CR10 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 CR10 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 CR10 checks for the presence of the Storage Modules. If one is not present, the CR10 does not attempt to output data to it. Instead, the CR10 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 CR10, 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 CR10 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 SM has been connected to the CR10 during an execution of P96, the user can:

•Leave the SM connected for a time period longer than an execution interval OR

•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 CR10 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 CR10.

4.5.3*8 DUMP TO STORAGE MODULE

In addition to the on-line data output procedures described above, output from CR10 Final Storage to the SM192 and SM716 can be manually initiated in the *8 Mode. The procedure for setting up and transferring data is as follows:

1.Connect the CR10KD Keyboard/Display (or terminal) and the Storage Module in parallel to the CR10 using the SC12 cable. For terminals, an SC32A will be needed. See Section 5 for interfacing details.

2.Key in the appropriate commands as listed in Table 4.2-1.

4.6*9 MODE -- STORAGE MODULE COMMANDS

The *9 Mode is used to issue commands to the Storage Module (from the CR10) using the CR10KD or a terminal/computer. These "commands" are like * Modes for the Storage Module and in some cases are directly analogous to the CR10 * 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 CR10. The operations with the Storage Module are not directly analogous as may be seen in Table 4.6-1 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 CR10 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 CR10 responds: 9N:00

Where N is the address which was entered. You may now enter any of the commands in Table 4.6-1 (key in the command number and enter with A). Most commands have at least

4-8
