Appendix G. Using P80 to Redirect Final Storage Data to Input Locations

The following section of code provides an example of using datalogger Instruction 80 to redirect Final Storage data to input locations. This is not a complete program. Instructions would be included prior to this section of code to measure sensors, perform control functions, and provide initial data processing. All text entries preceded by a semicolon (;) are comments inserted by the programmer to explain the instructions.

Loc AIR TEMPC

 

Every sixty minutes the maximum air temperature will be stored in location #5.

No output data will be sent to Final Storage.

Instruction 80 should follow the instruction setting Flag 0, and should precede the output instructions. Keep in mind that all output processing instructions following Instruction 80 will be redirected to input storage until another Instruction 80 is used or until the program table is executed again (output defaults to Final Storage Area 1 at the beginning of the program table).
