Discrete PLC Programming

The following figure shows an application where the PLC
Communications Adapter Board has been set up for a full rack
(numbered rack 2) and the PLC controller program is using the
16–bit words for groups 1 and 2 for data transfer with the 1336
FORCE. You should refer to this figure to help understand the
following description.

In this example, the drive has been configured so that the data
coming into source parameter 331 is linked to parameter 367, ChA
Logic Cmd In. Information linked to the 1336

FORCE using the

16–bit output word for group 1 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 332. The 16–bit output word for group 2 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.
