Note the size of the Cfg data
It can happen under multi-configuration mode that the CfgData exceeds 64 bytes.
In such a case, the
CfgData [
}
76] must be enlarged.
7.5 Changing the Size of the Process Data
Exceeding the input data length (InputData)
By default, a maximum of 128 bytes of input data is set on the Bus Coupler.
The maximum lengths of the DP buffers can be changed, although the amount by which a length is
increased has to be subtracted from another, and the sizes must only be modified in 8-byte steps:
Exceeding the output data length (OutputData)
By default, a maximum of 128 bytes of output data is set on the Bus Coupler.
The maximum length of the DP buffer can be changed. The amount, however, by which one length is
increased must be taken away from another, and it must be noted that the sizes can only be changed in 8-
byte steps:
