In the SLIO module there is a 32 bit timer (µs ticker). With PowerON the timer starts
counting with 0. After 2
32
-1µs the timer starts with 0 again. PRIT_US represents the lower
2 byte of the µs ticker value (0 ... 2
16
-1).
Via the parameterization you may activate a diagnostic interrupt for the module. With a
diagnostics interrupt the module serves for diagnostics data for diagnostic interrupt
incoming
.
As soon as the reason for releasing a diagnostic interrupt is no longer present, the diag-
nostic interrupt
going
automatically takes place. All events of a channel between diagnostic
interrupt
incoming
and diagnostic interrupt
going
are not stored and get lost. Within this time
window (1. diagnostic interrupt
incoming
until last diagnostic interrupt
going
) the MF-LED of the
module is on.
The following errors are listed in the diagnostics data:
n
Error in project engineering / parameterization
n
Measuring range overflow
n
Measuring range underflow
n
Process interrupt lost
n
Power supply failed
DS - Record set for access via CPU, PROFIBUS and PROFINET. The access happens
by DS 01h. Additionally the first 4 bytes may be accessed by DS 00h.
IX - Index for access via CANopen. The access happens by IX 2F01h. Additionally the
first 4 bytes may be accessed by IX 2F00h.
SX - Subindex for access via EtherCAT with Index 5005h.
More can be found in the according manual of your bus coupler.
