Examples of Register Communication
The numbering of the bytes in the examples corresponds to the display without word alignment.
5.5.1
Example 1: reading the firmware version from Register 9
Output Data
Byte 0: Control byte
0x89 (1000 1001
)
bin
Explanation:
• Bit 0.7 set means: Register communication switched on.
• Bit 0.6 not set means: reading the register.
• Bits 0.5 to 0.0 specify the register number 9 with 00 1001
• The output data word (byte 1 and byte 2) has no meaning during read access. To change a register,
write the required value into the output word.
Input Data (answer of the Bus Terminal)
Byte 0: Status byte
0x89
Explanation:
• The terminal returns the value of the control byte as a receipt in the status byte.
• The terminal returns the firmware version 0x3341 in the input data word (byte 1 and byte 2). This is to
be interpreted as an ASCII code:
◦ ASCII code 0x33 represents the digit 3
◦ ASCII code 0x41 represents the letter A
The firmware version is thus 3A.
