E_DbgDirection
This variable type can be used by buffer blocks or protocol blocks for configuring the debug output.
TYPE E_DbgDirection :
(
eDbgDirection_OFF := 0,(* Disabled (no debug oputput) *)
eDbgDirection_IN := 1,(* Enabled only for incomming data *)
eDbgDirection_OUT := 2,(* Enabled only for outgoing data *)
eDbgDirection_ALL := 3(* Enabled for incomming and outgoing data *)
);
END_TYPEValue | Meaning |
|---|---|
eDbgDirection_OFF | Disables the debug output |
eDbgDirection_IN | Activates output of incoming telegrams |
eDbgDirection_OUT | Activates output of outgoing telegrams |
eDbgDirection_ALL | Activates output of incoming and outgoing telegrams |
Example:
The debug output itself can be realized with the ADSLOGSTR function, for example.
In a ring buffer the debug output could be controlled via the variable in the following way, for example:
- If the value is eDbgDirection_IN or eDbgDirection_ALL the debug output is triggered if a new value is added to the buffer;
- If the value is eDbgDirection_out or eDbgDirection_ALL the debug output is triggered if a value is removed from the buffer;
