Option Adapters
The Momentum Option Adapters, mounted on Momentum I/O Bases, can be used to
enhance the capabilities of the Momentum Processor Adapters that mount on top of
the Option Adapter, to fulfill a variety of roles. The option adapters allow you to
network your local logic solvers together into an intelligent subsystem as part of a
larger Schneider application, or into a standalone, integrally networked system with
local controllers with extended I/O.
The Momentum Option Adapters are:
b 172 PNN 210 22 - one Modbus Plus communication port
b 172 PNN 260 22 - two redundant Modbus Plus communication ports
b 172 JNN 210 32 - one general-purpose serial communication port, RS232/RS485
selectable
Each of these Option Adapters provides an on-board, time-of-day (TOD) 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 two AAA batteries.
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
Momentum product line to a broad spectrum of applications. You can use the port
to connect to other processors, such as other Momentum Processor/Option
Adapters, other PLCs enabled with Modbus Plus, Momentum Modbus Plus
Communication Adapters and I/O Bases, and 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 RS232/485) to the I/O Base. You can use the port to
connect to other processors, such as other Momentum Processor/Option Adapters,
and other devices, such as operator interface panels and display marquees.
Momentum Processor Adapters have a number of PC programming software options
available. You can program your Processor Adapter via the Modbus RS232 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 specific information, see the appropriate Momentum, ProWORX,
and Concept programming software documentation.
