Quatech INTERBUS S Structure of the in- and output data for CAL from firmware WE, Mode class

Structure of the in- and output data for CAL (from firmware WE)

Mode class 4:

The data is in the 2 Byte objects #BK_AI2W0_XXX, #BK_AI2W1_XXX and #BK_A02W0_XXX. Each module has 2 values.

Input

Content

Output byte0, Output byte1

Output byte2, Output byte3

Description

1.and 2. Output byte

3.and 4. Output byte

Mode class 0:

The description of the data is the same as for class 4 mode. The data is put into objects No.1, No.2 and No.3 (read/write 2 Byte analog).

Attention:

The control byte allows the changing of the registers of the module. It must always be 0 in order to avoid a change in the registers. A wrong mapping can change the function of the module!
