7.3.1
Parameter sets
In the BPS 37 three different parameter sets are administered:
• parameter set with the default settings in the ROM
• current parameter set in the EEPROM
• working copy of the current parameter set in the RAM
Before a parameter set is loaded into the memory of the BPS 37 processor, the validity of
the parameter set is verified using checksums.
Factory default parameter set
This parameter set contains the default settings made ex works for all BPS 37 parameters.
It is permanently stored in the ROM of the BPS 37. The parameter set with the default
settings is loaded into the memory of the BPS 37,
• the first time the device is commissioned after delivery
• following the command "Factory Default" in the parameterisation program
• if the checksums of the current parameter set are invalid.
Current parameter set
In this parameter set, the current settings for all device parameters are stored. When the
BPS 37 is in operation, the parameter set is stored in the EEPROM of the BPS 37. The
current set can be stored:
• by copying a valid parameter set from the host computer
• by means of an off-line set-up with the PC set-up program BPSConfig
The current parameter set is loaded into the memory of the BPS 37:
• each time the supply voltage is connected
• following a software reset
The current parameter set is overwritten by the parameter set with the default settings:
• by a parameter reset, see "Online commands" on page 27
7.3.2
Service Operating Mode
Setting the required parameters is carried out easiest in the 'Service' operating mode. The
Service operating mode makes the following defined operating parameters available on a
separately wired RS232 interface, independent from the BPS's configuration for standard
operation:
• transfer rate 9600 baud
• no parity
• 8 data bits
• 1 stop bit
• prefix: STX
• postfix: CR, LF
