Datalink A
PowerFlex 70 Parameter 300 [Data In A1] = "140", which points to Parameter 140 [Accel Time 1]
Ch1_Datalink_A_In[0] contains the Accel Time 1 value in seconds, where a "100" equates to 10.0 seconds.
PowerFlex 70 Parameter 301 [Data In A2] = "142", which points to Parameter 140 [Decel Time 1]
Ch1_Datalink_A_In[2] contains the Decel Time 1 value in seconds, where a "100" equates to 10.0 seconds.
The respective Ch1_Datalink_A_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 A1 (low) value for 16-bit Datalinks, low word for 32-bit Datalinks
word (1] = Datalink A1 (high) high word for 32-bit Datalinks
word [2] = Datalink A2 (low) value for 16-bit Datalinks, low word for 32-bit Datalinks
word (3] = Datalink A2 (high) high word for 32-bit Datalinks
