D.6 Data blocks
D.6.1 Templates for data blocks
The included library (FMx52LIB) contains a block template (UDT) for each data block. Based
on this UDT, you can create data blocks with user-specific numbers and names.
Optimizing the UDT
To save memory, you can delete unused data areas at the end of the UDT
CAM_CHANTYPE. Save the modified UDT under a different name.
You can then generate a channel DB based on this UDT that is optimized for your
application.
Functions that access deleted data areas can no longer be used.
The included UDTs for the machine and cam data are already tuned to the possible numbers
of cams. They can be optimized in increments of 16 cams.
D.6.2 Channel DB
Task
The channel DB forms the data interface between the user program and the FM 352
electronic cam controller. It contains and accepts all data required for controlling and
operating the module.
Configuration
The channel DB is divided into various areas:
Channel DB
Address* /version switch
Control signals
Checkback signals
Function switches
Trigger bits for write jobs
Trigger bits for read jobs
Done bits
Error bits
Job management for functions
Data for jobs
* You can enter the address in the parameter assignment interface.
