- Like on drive commands, __qh__, __q3__ and __qe__ may be used. For all scanned |
- variables, the corresponding step must be given. __ti__ may be used instead of |
- __mn__ for time preset. |
+ The presence of 4 argument parts is mandatory, but the order of |
+ the parts is not relevant. For every step variable, the corresponding |
+ center value must be given. |
+ If no step is given for a center variable, a step 0 is used. |
