EDSMF2178IB EN 3.0

Example:

Parameter data channel 2 (SDO2) of the controller with node address "4" is to be
deactivated. The master must send this command to the communication module via
parameter data channel 1 (SDO1).

In sending direction, the basic identifier for SDO2 has the value "1600" (basic identifier for
response: "1472").

Identifier = basic identifier + node address = 1604 (0x0644)

For deactivating the parameter data channel (= invalid), set bit 31 in I−1201, subindices 1
and 2 to "1". After this, enter the following values under subindices 1 and 2:

I−1201/1: 0x80000000 + 0x644 = 0x80000644

I−1201/2: 0x80000000 + 0x5C4 = 0x800005C4
