### Use of type conversion operators (e.g. REAL\_TO\_WORD) directly at the input `InputValue`

In this configuration, compiler error messages of type C0032 are generated; a download is not possible.

{% hint style="info" %}
Remedy:

Use of an intermediate variable of the explicit type `WORD` directly at the output of the type conversion operator. Connection of the intermediate variable at the input `InputValue`.
{% endhint %}
