This section describes the organization of data in the AutoMax Network
Communication Option board and how the network accesses the data.
4.1 Selecting a Register Map (FlexPak 3000 Drives Only)
There are two register maps available for the FlexPak 3000 drive: original and
alternate.
The original register map allows you to use programs developed for versions earlier
than 4.0 of the FlexPak 3000 drive. Register assignments for the original register map
are listed in chapter 5.
The alternate register map is similar to the original register map, except that the most
commonly accessed data is in the base drop area (Drop_1). The alternate register
map also includes functions that were added in regulator software version
4.2 . See
the FlexPak 3000 DC Drive Software Reference Manual , manual number D2-3405, for
details on the new version 4.2 features. Register assignments for the alternate register
map are listed in chapter 6.
Important: When a version 4.2 Regulator board is used as a replacement in an
existing AutoMax network that uses the ALTERNATE register map, you
may need to reprogram the master task so that it writes valid data in the
registers that are now being used (where previously they were marked as
reserved).
The register map is selected using the NETW REGISTER MAP SEL (P.914) parameter.
4.2 How the Control Source Selection Affects Data
Transfers
You can use the keypad to change parameter values when CONTROL SOURCE SELECT
(P.000) is set to NETWORK . However, changes made through the keypad might be
overwritten when the next network update occurs.
You cannot transfer data using the CS3000 OR WebPakCS software while CONTROL
SOURCE SELECT (P.000) is set to NETWORK .
4.3 About Network Transfer Rates
To transfer data, the Network Option board must be communicating with the master.
To transfer input data, the Network Option board must be communicating with the
master and
CONTROL SOURCE SELECT (P.000) must be set to NETWORK .
Data transfer rates between the Network Option board and Regulator board depend
on the type of data being transferred.
