7.1 General
Class State State This server shows the actual status of the hardware class.
Device ID State This server shows the device ID of the hardware module.
FPGA Version State FPGA version of the module in 16#XY (e.g. 16#10 = version 1.0).
Hardware Ver-
sion
State Hardware version of the module in format 16#XXYY (e.g. 16#0120 = version
1.20)
Serial Number State The serial number of the hardware module is shown in this server.
Retry Counter State This server increments when a transfer fails.
LED Control Output With this server, the application LED of the S-DIAS module can be activated
to find the module in the network more quickly. The following status are pos-
sible:
0 LED off
1 LED on
2 blinks slowly
3 blinks rapidly
Required Property This client is activated by default, i.e. this S-DIAS hardware module at this
position is absolutely necessary for the system and may under no circum-
stances be missing, disconnected or deliver an error, otherwise the entire
hardware is switched off. If the hardware module is missing, it returns an error
or if it is removed, this triggers an S-DIAS error. If this client is initialized with
0, this hardware module is not mandatory at the position. This means that it
can be removed at any time. However, which components identified as "not
required" should be selected with regard to the safety of the system.
Firmware Ver-
sion
State The firmware version of the hardware module is shown in this server.
Error Bits State In this server, the error bits of the module are shown. The respective bits mean
the following:
Bit 0 Not used
Bit 1 no Sync available
Bit 2 Flash Data CRC Error
Bit 3 Ram Data CRC Error
Bit 4 invalid EEProm version
Bit 5 Bridge 1 DC not OK
Bit 6 Bridge 2 DC not OK
Bit 7 incorrect gain setting of ADC1
– current setting does not match
the calibrated data
Bit 8 incorrect gain setting of ADC2
– current setting does not match
the calibrated data
Bit 9 Bridge1 filter is not yet filled
Bit 10 Bridge2 filter is not yet filled
The error bits 7 and 8 go to null as soon as the gain setting matches the de-
fined values. The application must ensure that the correct gain (as well as filter
type and filter depth) is set correctly after each restart.
This is necessary, since the calibration data no longer matches when the gain
is changed and the measurement results are thereby incorrect. If the gain
must be changed, a new calibration must be performed.
