What To Do
Block Call
STL Representation
CALL RES_RECV, I_RES_RECV
REQ:
R:
LADDR:
DONE:
ERROR:
STATUS:
Note
The parameters EN and ENO are only present in the graphical representation
(LAD or FBD). The block is started with EN = TRUE. If the function is completed
without errors, ENO = TRUE is set. To process these parameters, the compiler
uses the binary result BR.
The binary result is set to the 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
The RES_RECV FB works with an instance DB (I_RES_RECV). The DB number
is specified in the call. The data in the instance DB cannot be accessed.
Note
Exception: If the error STATUS == W#16#1E0F occurs, you can consult the
SFCERR variable for more details of the error (see Section 8.3). This error
variable can only be loaded via a symbolic access to the instance DB.
