The field bus master must be programmed in a way that bytes 115 to 118 are evaluated as a torque value
for the second channel.
6.4.4.6 Example of results output with field bus
The following example is to clarify the assignment of the parameters and the results values.
The result is displayed in clear text in Figure 6–55; Figure 6–56 displays the contents of the storage area
in hexadecimals. The contents of the data buffer are assigned to the results in Table 6–54; the meaning
of the results is displayed in Table 6–55.
