Rockwell Automation 160 DEVICENET (DN1) MODULE FRN 1-2.XX - Manual (Page 27)

Publication 0160-5.5 - September 1997
5-2 DeviceNet Parameter Descriptions
Parameters and EDS File
(Continued) Parameter values may be read or written via DeviceNet. Writing a
value to a parameter may configure drive operations such as the accel-
eration or deceleration rates. Writing a value to a parameter may also
configure DeviceNet operations such as which input or output assem-
blies are to be used for polled I/O communications with a master.
Reading a parameter’s value gives you status information.
Interface Select Parameter There are two different EDS files for each Bulletin 160. Each EDS
file has the Bulletin 160 parameters and DeviceNet parameters
grouped differently. When using a configuration tool, such as the
DeviceNet Manager, these EDS files will present different interfaces
to the user. A special parameter named Interface Select allows the
user to switch between these two interfaces. When P15 - [Interface
Select] has a value of 0, the Bulletin 160 SSC Interface is used and
when the value is set to a 1 the ODVA Drive Profile Interface is used.
Bulletin 160 SSC Interface When P15 - [Interface Select] has a value of 0, the Bulletin 160 SSC
Interface is selected. This interface (parameter set) contains all of the
parameters described in the Bulletin 160 SSC User Manual, plus a
few extra parameters to configure the operation of the Communica-
tion Module on the DeviceNet network.
ODVA Drive Profile Interface When P15 - [Interface Select] has a value of 1, the ODVA Drive Pro-
file Interface is selected. This interface contains standard parameters
that are defined in the ODVA (Open DeviceNet Vendors Association)
Drive Profile, plus some extra parameters to configure the operation
of the Communication Module on the DeviceNet network. The inter-
face also has parameters to configure some features of the 160 SSC
drive that are not included in the ODVA Drive Profile. This interface
differs from the Bulletin 160 SSC Interface in many aspects. For
example, speeds are defined in RPM rather than Hz and the parameter
numbers have different meaning than the parameters defined in the
Bulletin 160 SSC User Manual. This interface is included to give the
Bulletin 160 SSC drive true interoperability with other DeviceNet
equipped drives that adhere to the ODVA Drive Profile. See
Appendix C for the parameter set for the ODVA interface.
