FX16 Master Controller Technical Bulletin 77
Gateway Function (LP-FX16X Rev. A Only)
The FX16 Master Controller (Rev. A) features the Gateway object. The
Gateway object can monitor up to 16 slave devices on the Local Link
Extension Bus that are not part of a Distributed Application. These
slave devices can be FX controllers with an RS-485 N2 Open
communication card or N2 Open VND (Vendor) devices that are
Metasys compatible. System 91 N2 devices (DX-9100 and TC-910x)
are also supported.
When you evaluate the performance of the Local Link Extension Bus,
you must include controllers connected as devices monitored by a
Gateway object. You should connect no more than 16 devices and the
number of physical input/output data points should not exceed 300 for a
reasonable response (3 to 4 seconds on average) within a control
sequence. If you require a faster response time, then you must reduce
the number of devices and data points. You should also perform a
physical test made with the configuration to measure the actual response
times.
Use the Gateway function to connect the sensor and/or actuators devices
with an N2 Open serial interface (such as a variable speed motor drive).
