Corrected from:
- Library: L_MC2P_Cam (FAST Motion) V03.10.00.00
(contained in PLC Desginer V03.10.00.00 and higher)
Response of the new version:
The function restriction has been corrected. The described behaviour no longer occurs.
What happens?
Exception in the control program.
When does this behaviour occur?
The CAM editor in the PLC Designer was used to create a curve by entering grid points.
The curve is linked to a CamRef object automatically generated by the CAM editor.
The behaviour occurs in the following actions:
1. ResetWarm, ResetCold
2. When changing a curve in the project in offline mode and downloading the new curve track (without downloading the project)
--> in this case, communication with the PLC Designer will freeze as well (mains switching for the controller is required).
3. In the application, a new curve is read into the CamRef object which has already read in the grid-point table (irrespective of the format of the new cam track).
Which products are affected?
- Library: L_MC2P_Cam (FAST Motion)
(contained in the PLC Designer)
Short-term measures:
Create the curve (CamTrack) as usual via the cam tool of the PLC Designer. Read the cam into a manually instantiated CamRef object of the application.
The declaration can e.g. be performed in a global variable list.
Declaration example:
CamRefUser_Data :ARRAY[1..XXX] OF L_MC2P_CamDataObject;
CamRefUser :L_MC2P_CamRefFromFile := (sFileName := 'CamTrack1.lcp', itfCamData := CamRefUser_Data[1], udiCamDataCount := YYY, xReloadable := FALSE);
XXX = (number of grid points / 3) + 2
YYY = (number of grid points / 3) + 1
CamTrack1.lcp: Name of curve initially linked
CamRefUser: CamRef object (corresponds to a CamRef object like the object in the CAM editor below the "Profile Reference" folder)
CamRefUser_Data: Data array for the cam data to be read in.
-> The curve defined during initialisation will automatically be read in when the program is downloaded.
-> The generated "CamRefUser" instance can be directly connected with a cam-processing FB, e.g. MC_CamIn.
-> For information on how to reload cam data in active applications: see the documentation L_MC2P_CamRefFromFile.
