Section 12. Memory and Data Storage 12.2 Memory Conservation One or more of the following memory saving techniques can be used on the rare occasions when a program reaches memory limits: • Declare variables as DIM instead of Public. DIM variables do not require buffer memory for data retrieval. • Reduce arrays to the minimum size needed. Each variable, whether or not part of an array, requires about the same amount of memory. Approximately 70 variables will fill available memory. • Use variable arrays with aliases instead of individual variables with unique names. Aliases consume less memory than unique variable names. 12.3 Memory Reset Three features are available for complete or selective reset of CR200(X) memory. 12.3.1 Full Memory Reset Full memory reset occurs when an operating system is sent to the CR200(X) using DevConfig. A full memory reset does the following: • Clears and Formats CPU: drive (all program files erased) • Clears SRAM data tables • Clears Status Table Elements • Restores settings to default • Initializes system variables • Clears communications memory 12.3.2 Program Send Reset All SRAM and CRD: data are erased when user programs are uploaded. This will occur even when a program with identical data tables is sent to the CR200(X). 12.3.3 Manual Data Table Reset Data table memory is reset using the ResetTables field of the Status table. Change the value from 0 to 8888 to reset all data tables. 130
Section 13. Telecommunications and Data Retrieval Telecommunications, in the context of CR200(X) operation, is the movement of information between the CR200(X) and another computing device, usually a PC. The information can be programs, data, files, or control commands. Telecommunications systems require three principal components: hardware, carrier signal, and protocol. For example, a common way to communicate with the CR200(X) is with PC200W software by way of a PC COM port. In this example, hardware are the PC COM port, the CR200(X) RS-232 port, and a serial cable. The carrier signal is RS-232, and the protocol is PakBus®. Of these three, a user most often must come to terms with only the hardware, since the carrier signal and protocol are transparent in most applications. Systems usually require a single type of hardware and carrier signal. Some applications, however, require hybrid systems, which utilize two or more hardware and signal carriers. Contact a Campbell Scientific applications engineer for assistance in configuring any telecommunications system. Synopses of software to support the various telecommunications devices and protocols are found in Section Support Software (p. 143). 13.1 Hardware and Carrier Signal Campbell Scientific supplies or recommends a wide range of telecommunications hardware. TABLE. CR200(X) Telecommunications Options (p. 131) lists telecommunications destination, device, path, and carrier options which imply certain types of hardware for use with the CR200(X) datalogger. Information in TABLE. CR200(X) Telecommunications Options (p. 131) is conceptual.
