3 Eliminated Software Bugs
3.1 User Interfaces
3.1.1 Behaviour during start-up
Starting from operating system version 3.00 of the NANO-C, the text "data error" would
appear on a connected user interface at power-up. This was mainly dependent on the
duration of the power-on delay and did not influence the functioning of the user interface.
Starting from operating system version 3.01, the text "P-SPS timeout" will be shown on
the user interface, until the initialising phase of the NANO-C has been completed.
3.1.2 JX-SIO inputs and outputs
The digital inputs and outputs of the JX-SIO expansion modules with the I/O numbers
7001 through 7964 can now be read and written via user interface.
3.2 Display Instructions
When registers are mapped onto a JX2-SER1 or a JX"-PRN1 module with the help of
DISPLAY
_
REG,
the amount of characters to be edited will be limited to the field width set
in register
2812
"Field width for the display of interregisters“.
Up to version 3.00, 10 characters would always be edited.
3.3 Network Operation
The NANO-C will only accept a token in a JETWay network, if it has been configured as a
master. The token will be passed on among the individual masters belonging to a
JETWay network.
3.4 Application Program RAM-> Flash
Now, the copying process of the application program from RAM into flash is interrupted by
the NANO-C; this way, further data can be exchanged via serial interfaces due to the
interruption.
Especially in the programming system JetSym, setting a long timeout time for the
interface will not be necessary.
3.5 System Bus
3.5.1 Erroneous behaviour of the analog outputs in
Smart I/O modules
For Smart I/O modules, erroneous behaviour of the analog outputs can be configured.
The Smart I/O modules will recognize an interruption of the system bus connection to the
NANO-C and will then output the configured values at the analog outputs.
Up to version 3.00, the configuring data would not be transmitted correctly; at the analog
outputs value 0000
hex
would always be output.
