Parameter and type
REQ IN
Timezone IN
DONE OUT
BUSY OUT
ERROR OUT
STATUS OUT
To manually configure the time zone parameters for the CPU, use the "Time of day"
properties of the "General" tab of the device configuration.
Use the SET_TIMEZONE instruction to set the local time configuration programmatically.
The parameters of the "TimeTransformationRule (Page 289)" structure assign the local time
zone and timing for automatic switching between standard time and daylight saving time.
Condition codes: ENO = 1 means no error occurred. ENO = 0 means an execution error
occurred, and a condition code is provided at the STATUS output.
STATUS Description
(W#16#....)
0 No error
7000 No job processing active
7001 Start of job processing. Parameter BUSY = 1, DONE = 0
7002 Intermediate call (REQ irrelevant): Instruction already active; BUSY has the value "1".
808x Error at x-th component: For example 8084 indicates that DaylightStartWeekif is not a value from 1to 5.
