Discrete PLC Programming
The following figure shows an application where the ControlNet
Adapter Board has been set up for rack 2 and the PLC program is
using the 16-bit words for groups 0 and 1 for data transfer with the
1336 FORCE. You should refer to this figure to help understand the
following description.

Data Transfer
In this example, the drive has been configured so that the data
coming into source parameter 322 is linked to parameter 367, ChA
Logic Cmd In. Information linked to the 1336
FORCE using the
16-bit output word for group 0 of rack 2 must be a 16-bit word
where the bits are defined by the description of parameter 367.
Parameter 101, Velocity Ref 1 HI, has been linked to source
parameter 323. The 16-bit output word for group 1 of rack 2 must be
a 16–bit signed integer whose value is within the allowable range of
values in drive units for parameter 101.
