Parameterization
8.1.4 Programming Mode
As long as the programming switch (S12) is in 'OFF' position, the module is in 'normal operation'. By
switching S12 to 'ON' the module gets into 'Programming' mode, no matter which current operating
mode it had been in.
If the programming switch is already on 'ON' during power-ON, the default settings become active and
all possibly stored 'special configurations' will be overwritten. If the programming switch is only put to
'ON' after power-on, however, the parameters which can only be set via SDO remain stored.
The programming mode is signalized as follows:
•
•
•
the green operation LED is switched off
the green mode LED is permanently on
the red module-error LED blinks slowly as long as the programming switch is 'ON'
In programming mode all outputs are switched off.
During this phase the switches S1 ... S9 can be set in accordance with the following chapters. Each time
the switch is turned the green operation LED blinks.
Only when the programming switch is turned from ‘ON’ to ‘OFF’ the set configuration (definition of
inputs and outputs) is taken over into a non-transient memory.
After a successful programming the blinking interval of the red module-error LED becomes shorter. For
safety reasons the programming mode can only be left by switching off the supply voltage.
Before switching-on the supply voltage again, the DIP-switches for the address setting and the CAN bit
rate (S1...S11) have to be set to their current values again!
All parameters which can be set via DIP-switch in the programming mode can also be set via SDO (see
page 28). For this, however, you need a suitable configuration tool.
