Communication via Function Blocks
6.6 Use of function blocks to output message texts to a printer
Block call
STL representation
CALL
Note
The parameters EN and ENO are only present in the graphical representation (LAD or FBD).
To process these parameters, the compiler uses the binary result BR. The binary result is set
to signal state "1" if the block was terminated without errors. If there was an error, the BR is
set to "0".
Assignment in the data area, instance DB
The FB P_PRINT_RK works together with an I_PRINT instance DB. The DB number is
passed on with the call. The instance data block is 40 bytes long. Access to the data in the
instance DB is not allowed.
Note
Exception: If the error STATUS == W#16#1E0F occurred, you can consult the SFCERR or
SFCSTATUS variable for additional details. See "Calling the SFCERR or SFCSTATUS
variable" for more information.
