Static PDO mapping
Dynamic PDO mapping
The tables provide the possible and the selected PDO mapping entries. To move one entry from left to right or vice versa use the arrow keys or double-click at an entry.
Table "PDO-mappable Sub indices" lists all possible PDO mapping entries inclusive the enabled dummy mappings.
For the configuration of RPDOs the possible PDO mapping entries are
built from objects with PDO Mapping enabled
and the Access "Read Write", "Read Write Write" or "Write Only".
For the configuration of TPDOs the possible PDO mapping entries are
built from objects with PDO Mapping enabled
and the Access "Read Write", "Read Write Read" or "Read Only".
The object properties can be specified about:
Line 0 > Object Dictionary > ... Segment > object sub-index > tab Structure > PDO Mapping
Line 0 > Object Dictionary > ... Segment > object sub-index > tab Structure > Access
The dummy mapping can be specified about:
Line 0 > EDS/XDD Settings > Dummy Mapping
Table "Mapping Entries" lists all selected and valid PDO mapping entries.
Please note that a PDO mapping entry is not removed automatically from table "Mapping Entries" when the PDO Mapping property of the mapped object is switched off.
The static PDO mapping is configurable about:
Line 0 > Object Dictionary > Communication Segment
> PDO Communication object
> tab Mask > Dynamic Mapping > Enable dynamic PDO Mapping: off.
The sub-indices of the PDO mapping objects are changed
depending on the configured PDO mapping automatically.
That means a sub-index is deleted when a PDO mapping entry is removed
and a sub-index is added when a PDO mapping entry is selected.
The number of PDO mapping entries in sub-index 0 of the PDO mapping object
is also changed automatically.
The Access right for all sub-indices of the PDO mapping object is set to "Constant" automatically, i.e. the PDO mapping is fixed and can not be changed during runtime.
The dynamic PDO mapping is configurable about:
Line 0 > Object Dictionary > Communication Segment
> PDO Communication object
> tab Mask > Dynamic Mapping > Enable dynamic PDO Mapping: on.
The sub-indices of the PDO mapping objects are not changed depending on the configured PDO mapping automatically. That means no sub-index is deleted or added. Only the number of PDO mapping entries in sub-index 0 of the PDO mapping object is modified automatically.
The Access right for all sub-indices of the PDO mapping object is set to "Read Write" automatically, i.e. the PDO mapping can be modified during runtime.
The implemented sub-indices for the PDO mapping object indicate the maximal number of PDO mapping entries for the dynamic PDO mapping during runtime.
