SECTION 11. OUTPUT PROCESSING INSTRUCTIONS Code Result xxxl SECONDS (with resolution of 0.125 sec.) xxlx HOUR-MINUTE xx2x HOUR-MINUTE,2400 instead of 0000 xlxx JULIAN DAY x2xx JULIAN DAY, previous day during first lxxx minute of new day YEAR Any combination of Year, Day, HR-MlN, and seconds is possible (e.9., 1011: YEAR, HRMtN, SEC). *** 78 SET HIGH OR LOW RESOLUTION *** DATA STORAGE FORMAT FUNCTION This instruction enables high resolution (5 character) or low resolution (4 character) final data storage format. Instruction 78 should be entered ahead of the output instructions for which the specified resolution is desired. The default format is low resolution. At the beginning of each program table execution, the low resolution format is automatically enabled. PARAM. DATA NUMBER TYPE DESCRIPTION 01: 2 O=lowresolution; 1 = high resolution Outputs Generated: 0 *** 79 SAMPLE ON MAXIMUM OR *** MINIMUM FUNCTION Instruction 79 samples specified input location values at the time a new maximum or minimum value is detected by a previous Maximize (73) or Minimize (74) Instruction. When the Output Flag is set, the values copied to lntermediate Storage are transferred to Final Storage. lnstruction 79 must directly follow the maximum or minimum Instruction to which it refers. lf the previous f nstruction 73 or74-has more than 1 repetition, Instruction 79 samples whenever a new maximum or minimum is detected in any of the locations. lf sampling is to occur only when a specific input location shows a new maximum or minimum, the previous Maximize or Minimize Instruction should have one rep referring to that input location. PARAM. DATA NUMBER TYPE DESCRIPTION 01: 2 Repetitions (number of sequential locations to 02: sample) 4 Starting input location no. Outputs Generated: 1 for each repetition *** 80 SET ACTIVE STORAGE AREA T** FUNCTION Instruction 80 is used to redirect Output data to either of the Final Storage areas or to lnput Storage and to set the array lD for Final Storage. At the beginning of each table the Active Output area is set to Final Storage Area 1. When directed to FinalStorage, the second parameter can be used to set the output array lD. lnstruction 8O should follow the instruction setting flag 0. lf parameter 2 is 0, the array lD is determined by the instruction location number of Instruction 80 or by the instruction that set the Output Flag, whichever comes last. When data are sent to Input Storage, no array lD is sent. PARAM. NUMBER TDAYTAPE 01: 2 02: 4 DESCRIPTION Storage area option 00 or 01 = Final Storage Area 1 02 = FinalStorage Area2 03 = Input Storage Area Starting input location destination if option 03 Output Array lD if options 0-2 (1-511 are valid lDs) *** 82 STANDARD DEVIATION IN TIME *** FUNCTION Calculate the standard deviation (STD DEV) of a given input location. The standard deviation is calculated using the formula: s = ((rxi2 - (xX,)z7p;7x;1/2 where Xi is the ith measurement and N is the number of samples. PARAM. NUMBER TDAYTAPE DESCRIPTION 01: 02: 2 Repetitions 4 Starting input location no. Outputs Generated: 1 for each repetition 11-5
