3.3.11 Serial parameterisation interface RS232 and RS-485- [X5]
It permits parameterisation of the controller as well as downloading of the parameter set
and firmware through an RS232 zero modem interface with up to 115 KBit/s.
The interface can be used either as an RS232 interface or alternatively as an RS -485
interface. Simultaneous use is not possible, since both interfaces use the same UART in
the DSP.
3.3.12 SD cardholder – [X12]
To permit saving of control parameters as well as the complete controller firmware, a
connection possibility for an SD memory card (popular storage medium for digital
cameras) has been incorporated. The connection is designed as a “push-push” holder for
reasons of quality perception.
3.3.13 SD memory card
Via the SD memory card, parameter sets can be loaded or firmware can be downloaded.
A menu in the configuration software allows you to specify a set of parameters on the
memory card, and load it or save it.
Note
When a parameter set is loaded from the memory card, the newest
parameter set is always loaded.
Also, the parameter set can be used to specify whether firmware and/or a parameter set is
to be loaded from the memory card automatically on activation.
If automatic firmware download (DIP switch 8 = 1) is activated or there is no valid
firmware in the controller, a check is performed at initialisation whether an SD memory
card is inserted, and if so, initialises it. If there is a firmware file on the card, it is checked
first (device type, checksum). If no fault is found, the firmware is transferred from the card
to the controller and saved in the FLASH program.
If the Load automatic parameter set is activated via the commissioning software, the
system checks whether a card is inserted when the firmware is started and it is initialised
if applicable.
