4.3 Time-based IO
Status parameter
Error codes or status information is output as double word at the Status output.
The double word is divided as follows:
Error code Meaning
(DW#16#...)
z0yywwww Error of a system function:
during startup (z = 1)
•
during normal operation (z = 0)
•
System functions with subordinate use are coded in yy: See table with error codes.
wwww specifies the RET_VAL of the system function. The error information is available in the help for the
system function.
z0yy0000 An error that does not originate in a system function. This error receives a consecutive error number yy.
The error can occur:
during startup (z = 1)
•
during normal operation (z = 0)
•
Table with error codes
Error code Meaning
(DW#16#...)
00000000 No error.
10010000 The assigned number of the digital input at the Channel
input parameter is outside the permitted range
(depending on addressed module and channel
configuration).
10020000 The TIO_DI instruction is not called in an isochronous
OB. The instruction can only be used without errors in an
isochronous OB.
10030000 An error occurred when reading the HWID input
parameter.
x0040000 The data in TIO_SYNC_Data is invalid/incorrect.
1005xxxx An error has occurred during execution of the RD_SINFO
system function. The low word xxxx displays the error
information of the RET_VAL return value from
RD_SINFO.

Solution
—
Correct the value at the Channel input
parameter.
Make sure that TIO_DI is called in a
"Synchronous Cycle" or "MC-PostServo" OB.
Check the value at the HWID input parameter.
Specify the hardware identifier of the TIO module
from its module properties in the hardware
configuration. An internal system constant of
data type Hw_SubModule is available for the
symbolic addressing.
Check the TIO_SYNC instruction and the
interconnection of its TIO_SYNC_Data output.
Read the description of the RD_SINFO in the
•
STEP 7 (TIA Portal) information system.
Make sure that TIO_DI is called in a
•
"Synchronous Cycle" or "MC-PostServo" OB.
