7-20 ControlLogix w/1769-ADN DeviceNet Ladder Example Program
Channel 2 and Channel 3 ladder subroutines are similar to the Channel 1
subroutine and are not provided.

Datalink C
PowerFlex 70 Parameter 304 [Data In C1] = "101", which points to Parameter 101 [Preset Speed 1]
Ch1_Datalink_C_In[0] contains the Preset Speed 1 value in hertz, where a "100" equates to 10.0 Hz.
PowerFlex 70 Parameter 305 [Data In C2] = "102", which points to Parameter 102 [Preset Speed 2]
Ch1_Datalink_C_In[2] contains the Preset Speed 2 value in hertz, where a "200" equates to 20.0 Hz.
The respective Ch1_Datalink_C_Out's point to the same parameters so the values can also be read. Note
these do not have to be equal and are done in the example program for demonstration purposes only
(so changes can be viewed).
The format is:
word [0] = Datalink C1 (low) value for 16-bit Datalinks, low word for 32-bit Datalinks
word (1] = Datalink C1 (high) high word for 32-bit Datalinks
word [2] = Datalink C2 (low) value for 16-bit Datalinks, low word for 32-bit Datalinks
word (3] = Datalink C2 (high) high word for 32-bit Datalinks
