SINUS PENTA
PROGRAMMING GUIDE
436/486
The correspondence
between the exchanged value and the real value (in volts) of the analog outputs is as follows:
Word 10: PID feedback from FIELDBUS
The PID feedback (M049) can be sent from the fieldbus if at least one of the parameters C288 to C290 is set as
6:Fieldbus.
The value sent by the Master to the Sinus Penta as the PID feedback must be multiplied by 100.
E.g. In order to send a PID feedback of 50%, the word must contain the value 5000
10
or 111110100
2
(50%
10
x 100 =
5000
10
).

Word 11: Type of cycle required
The word states the cycle required:
0x40: Write cycle
0x80: Read cycle
For the “Read cycle”, the field including the read address (Word 12) is to be completed beforehand.
For the “Write cycle”, the field including the write address (Word 12) as well as the field including the value to be written
(Word 13) are to be completed beforehand.
NOTE
At the end of each read/write cycle or
between any two cycles, enter value “0x00” in Word
11.
Word 12: Modbus address of the variable to read/write
Includes the Modbus address of the variable to be read (read cycle) or written (write cycle).
NOTE In order to save a parameter to non-volatile memory, see I009 Parameter save.
Word 13: Value to be written
Only in case of write cycles, it includes the value to be written to the address required.
