PI service: TMMVTL
Prepare magazine location for loading, unload tool
Function:
This PI service is used both to load and unload tools. Whether the PI initiates a loading or
unloading operation depends on the assignment between the real locations and the from
parameters and to parameters: Loading ⇒ 'From' = Loading point/station, unloading ⇒ 'To' =
loading point/station
The TMMVTL PI service is used for all movements.
1. Loading and unloading (loading point ↔ magazine)
2. Loading and unloading (loading point ↔ buffer storage, e.g., spindle)
3. Relocation within a magazine
4. Relocation between different magazines
5. Relocation between magazine and buffer storage
6. Relocation within buffer storage
The following variables from the TM block are used to monitor case 1, 3, 4, 5:
magCmd (area no. = TO unit, line = magazine number)
magCmdState <- "acknowledgment"
The following variables from the TMC block are used to monitor case 2), 6):
magCBCmd (area no. = TO unit)
magCBCmdState <- "acknowledgment"
Load function
Prepares the specified real magazine for the specified channel for loading, i.e., traverses the
magazine to the selected location for loading at the specified loading point/station
(location_number_from, magazine_number_from) and inserts the tool.
When location_number_to = -1, an empty location for the tool specified by a T number is first
sought in the specified magazine and the magazine then traversed. After execution of the PI,
the number of the location found is listed in the TM area in component magCMCmdPar2 for
the real magazine of the channel.
With location_number_to = -2 and a valid magazine number, loading takes place into the
currently queued magazine position of the specified magazine. After execution of the PI, the
number of the location for tool loading is listed in the TM area in component
magCMCmdPar2 for the real magazine of the channel.
