13. CUSTOM MACRO
Time information can be read and written.
Table 13.2 (f) System variables for time information
#3001 This variable functions as a timer that counts in 1–millisecond
increments at all times. When the power is turned on, the val-
ue of this variable is reset to 0. When 2147483648 millisec-
onds is reached, the value of this timer returns to 0.
#3002 This variable functions as a timer that counts in 1–hour incre-
ments when the cycle start lamp is on. This timer preserves its
value even when the power is turned off. When 9544.371767
hours is reached, the value of this timer returns to 0.
#3011 This variable can be used to read the current date (year/month/
day). Year/month/day information is converted to an apparent
decimal number. For example, February 28, 2002 is repre-
sented as 20020228.
#3012 This variable can be used to read the current time (hours/min-
utes/seconds). Hours/minutes/seconds information is con-
verted to an apparent decimal number. For example, 34 min-
utes and 56 seconds after 3 p.m. is represented as 153456.
The control state of automatic operation can be changed.
Table 13.2 (g) System variable (#3003) for automatic operation control
Completion of an auxiliary
0 Enabled To be awaited
1 Disabled To be awaited
2 Enabled Not to be awaited
3 Disabled Not to be awaited
S When the power is turned on, the value of this variable is 0.
S When single block stop is disabled, single block stop operation is not
performed even if the single block switch is set to ON.
S When a wait for the completion of auxiliary functions (M, S, and T
functions) is not specified, program execution proceeds to the next
block before completion of auxiliary functions. Also, distribution
completion signal DEN is not output.
D Time information
D Automatic operation
