Result
The user data variant is switched with the next cycle.
Note
Information about user data changeover
The parameterized user data variant is set in the following cases:
• A "0" is written in byte 0 in the output data of a user data variant.
• Byte 0 in the output data of a user data variant contains an invalid value:
– Coding of the user data variant not available
– Available address space is not sufficient for the selected user data variant.

Note
Read the measured values solely via the RDREC instruc-

tion from a measured value data record.
Quality information about the measured values is always
•
available.
Available measured values depend on the configured
•
measurement data profile.
The user data are fixed and cannot be changed dynami-
•
cally. Alternatively, read the measured values acyclically
from a measured value data record via the RDREC in-
struction.
No quality information
•
Quality information about the measured values is always
•
available.
Depending on the user data variant, you must convert
•
the measured values in the CPU to physical values using
the supplied scaling factor.
One cycle elapses for each user data changeover.
•
Measured values from the next user data variant are thus
supplied with a slight time offset.
Alternatively, read the measured values acyclically from
a measured value data record via the RDREC instruc-
tion. Consistent measured values of a measuring cycle
are supplied.
