Parameters
Parameter Declaration Data type Function depending on MODE
REQ IN BOOL Execute function (start/read)
LADR IN WORD Base address of the module
MODE IN WORD Mode (start/read)
CHANNEL IN BYTE Channel to be read
OFFSET IN DWORD Address offset for reading (not FIFO operation)
RECORD IN ANY Memory for the read data
RETVAL OUT WORD Return value (0 = OK)
BUSY OUT BOOL Function is busy
TIMESTAMP OUT DWORD Time stamp (only at edge evaluation)
LEN INOUT DWORD Number of values to be handled per channel
n Depending on the set MODE when the bit is set the recording respectively the
reading may be started.
n Depending on the trigger condition at edge evaluation the monitoring of the config-
ured channel may be started respectively at manual operation the recording may be
started.
n The data are read from the module, if "read" is set at MODE.
Logical basic address of the module.
The FC/SFC 193 may be called with 3 different modes. The corresponding mode may be
set by the parameter MODE. The configured mode is executed by setting REQ. The fol-
lowing values are supported:
n 01h: Starts recording respectively edge monitoring depending upon the parameteriza-
tion.
n 00h: Read data within several cycles until BUSY = 0.
n 80h: Read data with one access.
Here the channel is specified to be read. With each call one channel may be read. This
parameter is irrelevant at start calls with MODE = 01h.
n Offset specifies an address offset for the reading process. By this you get access to
sub-ranges of the recorded data.
n The value for the maximum offset depends on the number of values, which were
recorded per channel.
n OFFSET is not supported in FIFO operation. It will be ignored.
n Here an area for the read values to be stored at may be defined.
n In FIFO operation every value of the selected channel may be read, which were
stored up to the time of start reading.
n Please regard that the buffer has a sufficient size for the data to be buffered, other-
wise an error is reported.
