SECTION 2. INTERNAL DATA STORAGE 2-3 Output Processing Instructions store data into Final Storage only when the Output Flag is set. The string of data stored each time the Output Flag is set is called an OUTPUT ARRAY . The first data point in the output array is a 3 digit OUTPUT ARRAY ID . This ID number is set in one of two ways: 1. In the default[...]

SECTION 2. INTERNAL DATA STORAGE 2-4 NOTE: All memory pointers are set to the DSP location when the datalogger compiles a program. For this reason, ALWAYS RETRIEVE UNCOLLECTED DATA BEFORE MAKING PROGRAM CHANGES. For example, assume the TPTR lags the DSP by less than 512 data points when the datalogger program is altered. On compiling, the TPTR is p[...]
