Write company head:
The entry ends either if 256 characters are received or if the character ETX (0x03) Strg-C is
contained in the character string.
Read company head:
By this command, the company head, which is stored in the 7280 measuring amplifier, is read-out.
Write all parameters:
The writing data block of all sensor parameters is identical with the receiving data block for
reading all parameters. However, for the writing of the sensor parameters a check sum and
the referring weighted check sum is required.
Read all parameters:
The read-out of all parameters from sensor 1 to sensor 10 occurs in following sequence:
Sensor designation
Final displayed value
Unit
Sensor type (adjustment type) / decimal point
Adjustment values 0 % load, 100 % load with 2 Bytes each
See command “read current sensor parameters”.
Change protocol setup:
Protocol status
1 Byte
0xXXXX XXXX
(binary coded)
|||| ||||
|||| |||1
... do not send final character
|||| ||1
... send CR/LF
|||| |1
... send CR
|||| 1
... send LF
Calculation of the check sum (CS) and the weighted check sum (gewCS):
The calculation occurs via all parameter bytes (without the command byte). At the CS all bytes
are added (overflows are not considered here). For the calculation of the gewCS, the CS is
added to the gewCS. At overflow, the gewCS is incremented by 1.
