Data Readout via Serial Interface 

All register codes from section 9. are also available for serial readout by PC or PLC. For 
communication the FU252 converter uses the Drivecom Protocol according to ISO 1745.  
All protocol details can be found in our manual 

SERPRO_2a.doc

  

 

 
 

To request for a data transmission you must send the following request string to the converter: 

 

EOT    AD1  AD2  C1  C2  ENQ 

EOT = control character (Hex 04) 
AD1 = unit address, High Byte 
AD2 = unit address, Low Byte 
C1   = register code, High Byte 
C2   = register code, Low Byte 
ENQ = control character (Hex 05) 
 
The following example shows the request string for readout of the actual frequency of input A 
(code :9) from a unit with unit address 11: 

 

ASCII Code:

After a correct request, the unit will respond: 

 

STX  C1  C2  x x x x x x x  ETX  BCC 
STX = control character (Hex 02) 
C1   = register code, High Byte 
C2   = register code, Low Byte 
xxxxx = readout data 
ETX = control character (Hex 03) 
BCC = block check character
