5.12 Function 100 : Read configuration
Request:
DevAddr 100 Index CRC16_H CRC16_L
Response:
DevAddr 100 PARA0 PARA1 PARA2 PARA3 PARA4 CRC16_H CRC16_L
Exception errors:
2 If index > 8
3 If message length is incorrect
32 If device is not yet initialised
Note:
This function supplies the information about the configuration of the device. Please use Function 32 instead of this function for
devices of Class.Group 5.20-5.24 and earlier. With function 32/33 you have access to a single parameter instead of all five
parameters.
A pressure transmitter can read two independent pressure sensors (P1 and P2), plus the temperatures of the respective
pressure sensors (TOB1 and TOB2) and an independent temperature ( T ).

5.13 Function 101 : Write configuration
Request:
DevAddr 101 Index Para0 Para1 Para2 Para3 Para4 CRC16_H CRC16_L
Response:
DevAddr 101 0 CRC16_H CRC16_L
Exception errors:
2 If wrong index
3 If message length is incorrect
32 If device is not yet initialised
Note:
This function supports altering of parameters. Please use Function 32 instead of this function for devices of Class.Group 5.20-
5.24 and earlier. With function 32/33 you have access to a single parameter instead of all five parameters.
Please note: With this function all five parameters (para0 .. para4) will be overwritten. To change a single parameter of the said
index all five parameters must be first read out with function 100. Now you can alter the desired parameter without accidentally
changing anything in the other four.
An incorrect parameter can damage the instrument!
