12.10.2 2 digital outputs with time stamp function − EPM−S310
By integration of the GSE file VI010C19.gse you can specify all counter parameters via a
hardware configuration.
The module has an FIFO (first−in−first−out) memory for 15 time stamp entries. Depending
on parameter setting, you can use the output area to transfer up to 15 time stamp entries
to the FIFO memory. The input process image provides information on the status of the
FIFO memory and the status of processing.
Read data: 4 bytes
Input area
Addr. Access Assignment
+0 Byte Bits 5 ... 0: running number (RN = Running Number) of the last FIFO entry
Bit 6: 1 (fixed)
Bit 7: 0 (fixed)
+1 Byte Bits 5 ... 0: running number of the next FIFO entry
Bit 6: 1 (fixed)
Bit 7: 1 (fixed)
+2 Byte Status
+3 Byte Number of time stamp entries in FIFO memory.
Running number: here you will find the running number of the time stamp entry last/next
written to the FIFO.
Status: The status informs you of the status of the FIFO memory:
Code 00
h
/80
h
: everything OK
Code 01
h
/81
h
: no following time stamp entry
Code 02
h
/82
h
: no new time stamp entries.
Code 03
h
/83
h
: FIFO memory is full. No new time stamp entries can be accepted.
If bit 6 of the last processed running number (RN) was set, the code is returned at 80
h
OR−ed.
)
Note!
Note that no more time stamp entries can be accepted once the FIFO memory
is full. You should always establish the status of the FIFO memory before the
transfer to ensure that your entries are accepted.
