11.1.3 'Online' commands for parameter set operations

Definitions
• <BCC type> Type of checksum calculation.
'0': No checksum
'3': XOR checksum (mode 3)
• <PS type> Parameter set type
'0': Current parameter set (data stored non-volatilely in the EEPROM)
'1': Reserved
'2': Standard parameter set (not changeable)
'3': Operating values (data in the RAM, will be lost after reset)
• <Status> Mode of parameter processing
'0': Does not perform a reset following the write operation; no other parameters follow.
'1': Does not perform a reset following the write operation; other parameters follow.
'2': Subsequently performs a reset, no other parameters follow.
• <Start address> Relative address of the parameter within the parameter set
• <Para0L> <Para0H>... <Para122L> <Para122H>:
Parameter-set data of the message. The sequence of the data is arranged identically
to the BCL 8, i.e. when a word is transmitted, first the low byte is sent then the high
byte. The parameter-set data is converted for transmission from HEX format to a 2-
byte-ASCII format. During the conversion, two ASCII characters - representing the
lower and higher nibbles - are created for each HEX value.
Example:
Decimal
4660
• Para0H = 31h, Para0L = 32h, Para1H = 33h, Para1L = 34h
Taking into consideration the maximum message length and the remaining command
parameters, a maximum of 123 bytes of parameter data (246 bytes of message data)
can be transmitted in a single operation.
Valid values: '0' ... '9', 'A' ... 'F'
• <Acknowledgement>:
Acknowledgement of the transmitted message
'0' valid transmission
'1' invalid message
'2' invalid length of message
'3' invalid block check type
'4' invalid block check checksum
'5' invalid data length
'6' invalid message data
'7' invalid start address
'8' invalid parameter set
'9' invalid parameter type
