Table CR6 File Attributes (p. 385) lists available file attributes, their functions, and when attributes are typically used. For example, a program file sent with the support software Program Send (p. 505) command, runs a) immediately ("run now"), and b) when power is cycled on the CR6 ("run on power-up'). This functionality is invoked because Program Send (p. 505) sets two CR6 file attributes on the program file, i.e., Run Now and Run on Power-up. When together, Run Now and Run on Power-up are tagged as Run Always. Note Activation of the run-on-power-up file can be prevented by holding down the Del key on the external keyboard display while the CR6 is powering up. Table 91. CR6 File Attributes Attribute Function Attribute for Programs Sent to CR6 with: Run Always (run on power-up + run now) Runs now and on power-up. a) Send (p. 496) 1 b) File Control2 with Run Now & Run on Power-up selected. c) Campbell Scientific mass storage device or memory card power-up3 using commands 1 & 13 (see table Powerup.ini Commands (p. 389) ). Run on Power-up Runs only on power-up a) File Control2 with Run on Power-up checked. b) Campbell Scientific mass storage device or memory card power-up3 using command 2 (see table Powerup.ini Commands (p. 389) ).
