Query Program Data / Load Program Data Commands
Query commands allow the computer to read program data from the indicator and load commands
allow the computer to write program data to the indicator. Each command consists of an L(load) or a
Q (query) and the two digit submenu number of the program mode sub menu illustrated on page 6.
All program mode sub menus are serially accessible except numbers 13, 15, 42, 43 and 44. These
commands are valid only in the program mode.
Decimal Points are not required by the command except for those program blocks which allow for a
floating decimal point. All other program blocks will insert the decimal point in the correct location.
