data) are written:
● magCBCmd (area no. = TO unit)
● magCBCmdState ← "acknowledgment"
Loading
● WVar2 "Location number_From", WVar3 "Magazine number_From"
The tool location of the magazine is moved to the loading station/location for loading and
the tool is loaded.

First, an empty location for the tool is searched for in the magazine. Then the empty location
of the magazine is moved to the loading station/location for loading and the tool is loaded.
After the PI service is carried out, the empty location number that is found is located in
"magCMCmdPar2" (BTSS block TM), real magazine of the channel.
● WVar4 "Location number_To" == -2
The tool is loaded into the current tool location of the magazine. After the PI service is
carried out, the location number is located in "magCMCmdPar2" (BTSS block TM), real
magazine of the channel.
Unloading
● WVar4 "Location number_To", WVar5 "Magazine number_To"
The tool location of the magazine is moved to the loading station/location for loading and
the tool is unloaded.
In the BTSS block TP (magazine data: location data), the magazine location of the removed
tool is designated as free.

numbers. The value -1 is assigned to an unused parameter.
