Diagnostics
In addition to information on the usability of the measured value, Pointek CLS200/300 can
actively report information on its own status. Diagnostics are important information, which
an automation system can use to introduce remedial measures.
Standard PROFIBUS DP mechanisms are used to transport diagnostic information and actively
report it to the Class 1 Master. For this, PROFIBUS DP provides a protocol to transmit
information ranked higher than user data to the Class 1 Master.
The content of the "Device status" parameter from the physical block is reported and, in
addition, information on whether a change of status has occurred (event arrived/ event
gone). The diagnostic object consists of 10 bytes (4 bytes standard diagnostics and 6 bytes
Extended diagnostics).

Possible cause
Sensor shows an error. Meas-
ured level too small
Sensor shows an error. Meas-
ured level too high
The function block is put out of
order with a target mode
command. A parameterized
safety value is supplied.
Sensor test in progress; no
error detected.
"Fail Safe" input condition is
met; the parameterized safety
setting is set to "keep last valid
value"
Value is not an automatic
measured value. This identifies
a parameterized, static substi-
tute value or a preset value.
After run-up, an initial value is
entered in the device memory.

ters or maintenance alarm
