POINTER TO SMC_GSentenceQueue
|
Pointer to the first element of an array of sentence queues, one for each subprogram call depth. The first is used for the main program. Note that the last queue is reserved for parsing subprogram declarations, so the effective maximum call depth is nNumSentenceQueues - 1. Read each cycle, not only at the rising edge of bExecute.
|
|
nNumSentenceQueues
|
UDINT
|
The number of sentence queues. Must be at least 1.

|
stSubprogramDeclRequest
|
STRING
|
If this input is set to an non-empty string, the last sentence queue will be used to read the subprogram with the given name in order to store the declaration in the symbol table. Read each cycle, not only at the rising edge of bExecute.

BOOL
|
TRUE signals that an error has occurred within the function block.
|
