5. CONFIGURATION
ATTENTION
It is not recommended the simultaneous commands interception to one same variable by two
or more CommandReceiver function blocks. Just one of the function blocks will intercept
correctly the command, being able to suffer undesirable interference from the others function
blocks if addressed to the same variable.
Parameter Type Description
bCommandAvailable BOOL
Indicates that a command was intercepted and the data
are available to be processed
sCommand STRUCT
This structure stores received command data, which is
composed by the following fields:
eCommand

sOperateParameters
The description of each field is in this section.
eStatus
ENUM
(TYPE_RESULT)
Out of function action from obtained result, according to
list:
OK_SUCCESS(0)
ERROR_FAILED(1)
Table 71: CommandReceiver Function Block Output Parameters
Note:
eStatus: Return of a register process of a communication point command interception. When the interception is regis-
tered with success OK_SUCCESS is returned, else ERROR_FAILED is. In case interceptor register failure, commands to the
determined point are not intercepted by this function block. TYPE_RESULT is defined in LibDataTypes library.
Supported commands are described on table below:
Parameter Type Description
