The abbreviations have the following meanings:

VK1 to VK6

Integers

.

Decimal point (if required)

NK1 to NK4

Decimal codes (if required)

“H” (48hex)

Character [H], transfer of parameter values in the ASCII hexadecimal format

VH1 to VH8

1 to 8 hexadecimal characters each [0 to 9; A to F]

“S” (53hex)

Character [S], transfer of parameter values in the string format

VS1 to VS240 1 to 12 visible ASCII characters each (no control characters)
“O” (4Fhex)

Character [0], transfer of parameter values in the octet string format

VO1 to VO240 Data block in hexadecimal code; each character corresponds to a nibble of the data block

Parameter value in the ASCII decimal format (110)
The ASCII decimal format (VD) is most often used. The values consist of the following:

1 leading negative sign (if required)
6 digits before the decimal point (VK1 to VK6)
1 decimal point (if required)
4 digits after the decimal point (NK1 to NK4) (if required)

Values from -214748.3648 to 214748.3647 can be displayed.

NOTE
In the ASCII decimal format (VD), the decimal point must not be transmitted if the value does not have digits
after the decimal point.

Parameter value in ASCII hexadecimal format (VH)
The LECOM-A/B protocol supports the transmission of hexadecimal parameter values with a length of:
• 2 characters (byte value)
• 4 characters (word/integer value)
• 8 characters (double word/long integer)
In the ASCII hexadecimal format, VH1 is the most significant and VH8 the least significant hexadecimal character.
Parameter value in the string format (VS)
By means of the string format (VS) of the protocol it is possible to transmit strings with a maximum of 20 characters in
both directions.
The SMV inverter can only send the string parameters (e. g. C200).
