Introduction
Modicon
™
Momentum
™
option adapters, mounted on Modicon Momentum I/O
bases, can be used to enhance the capabilities of the Modicon Momentum
processor adapters that mount on top of the option adapter. These option adapters
allow you to network your local logic solvers together into an intelligent subsystem as
part of a larger Schneider Electric application, or into a stand alone, integrally
networked system with local controllers with extended I/O.
Modicon Momentum option adapter models include:
172 PNN 210 22 - one Modbus Plus
™
communication port
172 PNN 260 22 - two redundant Modbus Plus communication ports
172 JNN 210 32 - one general-purpose serial communication port, RS 232 or
RS 485 selectable
Each of these option adapters provides an on-board, TOD (Time-Of-Day) clock that
is available to the application residing in the processor adapter. The clock is useful
for the scheduling of events, time-stamping operations and operator interface
requirements. In addition, each option adapter contains a battery-backup system that
maintains the application and its variables in the event of a power outage to the
processor adapter. The option adapter’s convenient side-door access allows for
quick replacement of the single 2/3 AA Lithium battery.
In addition to the TOD clock and battery backup features, the 172 PNN 210 22
adapter allows you to add networking to the intelligent I/O base. Model 172 PNN 260 22
allows you to add redundantly-cabled networking to the I/O base. This opens the
Modicon Momentum product line to a broad spectrum of applications. You can use
the port to connect to other processors, such as:
b
Other Modicon Momentum processor/option adapters
b Other PLCs enabled with Modbus Plus
b Modicon Momentum Modbus Plus communication adapters and I/O bases
b Other third party devices using Modbus Plus to communicate
Model 172 JNN 210 32 allows you to add a second, defacto-industry standard
Modbus port (selectable RS 232/485) to the I/O base. You can use the port to
connect to other processors, such as other Modicon Momentum processor/option
adapters, and to other devices, such as operator interface panels and display
marquees.
Programming software for Modicon Momentum
Modicon Momentum processor adapters have a number of PC programming
software options available. You can program your processor adapter via the
Modbus RS 232 serial port, or if using a Modbus Plus option adapter in conjunction
with a processor adapter, via an SA85 card installed in a PC and connected to the
same Modbus Plus network. For more specic information, see the appropriate
