III-5.1 AOCTET (data type conversion (No. 02))

Function AOCTET converts an analog value (X1) into the individual bytes (Ooct1-4) of a data type as used e.g. for trans

mission via the CAN bus ( see CPREAD / CPWRIT ). In the CAN notation, the bytes are transmitted in Intel format. Un

less connected instruments are in compliance with this notation, word or bytewise echange of the bytes may be

necessary.

The function works in both directions simultaneously ( analog > bytes / bytes > analog ) with separate data type adjust

ment in the parameters.

Analog inputs:

analog input value

Ioct1..4

analog input byte value 1

Analog outputs:

analog output value

Ioct1..4

analog output byte value 1

Parameters:

Parameter Description Value range Default

Ioct

data type of analog > byte conversion 0...999 999 [s]

Ooct

data type of byte > analog conversion
