You specify in the parameter data record for PROFIenergy which I/O modules (slots) are
controlled with the PROFIenergy commands.
The following table shows the content of the parameter data record for PROFIenergy, index
3, which you create yourself and can transfer to the interface module.

The specific behavior depends on the used I/O module (with a digital input module, for example,
the sensor supply is turned off or the outputs are without power supply and voltage supply with an
analog output module)
An analog output module (e. g. with the output range 0 mA to 20 mA, ± 20 mA) or a digital output
module issues the value "0".
The following table shows which error messages the feedback data record returns, if
necessary:
Table 2- 4 Error messages
Check the length of the data record
H
Error in header information
Check the data record header information
80E1
H
Parameter error
• at least one I/O module does
not support PROFIenergy
• A parameter value has been
incorrectly encoded
Check the co
ntent of the data record and correct the
parameter assignment error before starting the
"Pause". Parameter assignment errors which are
not corrected can result in incorrect I/O module
shutdown behavior.
