Substitution

To raise the reusability of the command interlocking, it is possible to substitute variable references. Substitution is possible for response, command and condition variables.

When substituting, the placeholder '*' is automatically replaced by name of the data point associated with the command input.

Example

Suppose we have the data points xyz_RM, abcRM and bool_RM.

Our mask is '*_RM'.

Datapoint name	Substitution text	Result	Comment
xyz_RM	xyz	xyz_RM	Data point exists, allocation successful
abcRM	<empty>	_RM	The masks is not correct, because _ is missing. Data point does not exist.
bool_RM	bool	bool_RM	Data point exists, allocation successful

Info

If the data point, for which the command interlocking is to be compiled, matches the response variable, then the substitution text is determined by the response variable. Otherwise, the substitution text is determined by the action variable oft the first action that fits the data point.

If the substitution text was successfully determined, the place holder '*' is replaced by this text.

This is why the following points should be considered for the names.

The names of the data points and the mask should allow for a clear allocation.
The names of the data points used for the response/command/condition variables, should be producible over the same substitution text.
If the response variable is substituted, but the command variable is not, it is important to consider that the command interlocking created for the command variable has to use the expected response variable.
An additional test run makes sure that the command interlocking of the response variable contains only actions with action variables using the same response variable in their compiled interlocking. Actions violating this rule will cause a warning and will be removed.
