278 Unidrive SP Advanced User Guide

menu for the relevant slot appears for the new module category with the default parameter values for the new category. The new parameters values
are not stored in EEPROM until the user performs a parameter save.
This parameter has different behaviour depending on the fieldbus type:
If Pr x.05 = 0 then the input and output cyclic data lengths will be configured independently by Pr x.38, Pr x.39 and Pr x.40.

Fieldbus Mode function
SM-PROFIBUS-DP
Sets the number of cyclic words and the format of the non-cyclic channel as follows:
Value = (X
× 100) + Y
X = Non-Cyclic Mode (0 = disabled, 1 = CTNC, 2 = Siemens compatible)
Y = Number of cyclic words (0 = none, 1-28 words)
If Pr x.05 is zero the input and output data lengths, and PPO types can be selected explicitly
– See SM-PROFIBUS-DP documentation for further details.
SM-INTERBUS
Sets the number of cyclic words and the number of words used by PCP
Value = (X
× 100) + Y
X = Non-Cyclic Mode (0 = disabled, 1 = PCP, 2 = CTNC)
Y = Number of cyclic words (0 = none, 1-10 words)
Note: X+Y must be 10 or less
SM-DeviceNet
Sets the number of cyclic words and the format of the non-cyclic channel as follows:-
Value = (X
× 100) + Y
X = Non-Cyclic Mode (0 = disabled, 1 = CTNC, 2 = Siemens compatible)
Y = Number of cyclic words (0 = none, 1-28 words)
If Pr x.05 is zero assembly objects should be explicitly set in Pr x.39 and Pr x.40 – See SM-
DeviceNet documentation for further details.
The maximum amount of polled data that can be transferred is 28 words.
