This block is a timer. It is possible to define daily, weekly, monthly, yearly time switch points and time switch points for working days or weekend days.
Mode: Daily: 1, weekly: 2, monthly: 3, yearly: 4, workday: 5, weekend: 6
The time value is always compared with the local time of the PLC, therefore the time value specified at the On and Off parameters must be specified as local time.

signal | Bool | Output signal |
actLocalTime | DTL | Current local time |
error | Bool | FALSE: No error / TRUE: An error occurred during the execution of the FB |
status | Word | 16#0000-16#7FFF: Status of the FB / 16#8000-16#FFFF: Error identification (see following Table) |
subFunctionStatus | Word | Sub function status code |
Code / Value | Identifier / Description |

16#0000 | STATUS_NO_ERROR Status: no error occurred |
16#8200 | ERR_NO_MODE_SELECTED Error: No suitable mode is selected, check input "mode" |
16#8600 | ERR_RD_LOC_T Error in function RD_LOC_T, see in `subFunctionStatus` |
subFunctionStatus
. In this case, the output value in status
indicates which command caused the error. In this case, refer to the TIA Portal Online Help section for information on the respective commands.The block offers various timer types, which are determined in the mode
parameter:
The time value is always compared with the local time of the PLC, therefore the time value specified at the On and Off parameters must be specified as local time.
Depending on the mode, the following formal parameters must be interconnected:
Mode | Mode | Required formal parameters |
---|---|---|
1 . | Daily timer |
|
2 . | Weekly timer |
|
3 . | Monthly timer |
|
4 . | Yearly timer |
|
5 . | Weekdays |
|
6 . | Weekend |
|
If the set start time equals the current local time of the controller, the output signal
is set to TRUE
. If the set switch-off time equals the current local time of the controller, the signal
output is reset again.
