MAXIFLEX Dual Serial Network Interface Module
Model M1580A Dual RS232/485 Programmable Network Interface Module
DATASHEET
FEATURES
•
Two Integral RS232/485 Serial Ports
•
Each Serial Port isolated independently to 1500Vac
•
Built in Modbus® and Conet/s protocols.
•
Programmable for custom protocols
•
Easy configuration using free software utility.
•
Check availability of protocol of your choice
•
Integrates any serial device into standard SCADA or DCS
or PLC systems.
•
The M1580A has identical functionality to the M1592A
modules, but with two serial ports for higher density
The M1580A Dual Serial Network Interface Module
(Dual Serial NIM) is designed specifically to allow serial
access to a wide range of third party serial devices in
either point-to-point or multi-drop configuration using
RS485. The provision of two independent serial ports
allows higher density Maxiflex installations to be
implemented
The Dual Serial NIM comes equipped with the Conet/s
protocol for peer-to-peer applications, or with Modbus
Master and Slave protocols for access to a wide range
of third party devices.
In addition, the Dual Serial NIM supports the
development of custom protocol drivers in the
EziFORTH programming language. Custom protocols
maybe downloaded to the module to communicate with
any device equipped with a RS232 or RS485 serial port.
All data is accessible by a SCADA, DCS or PLC via the
Maxiflex system CPU through a 3000 register Data
Interchange Table.
All system configuration data and dynamic data can be
read and written through this convenient table interface.
Using the supplied Omniset configuration utility,
advanced polling schemes may be easily set up without
the need for programming. All polling and
communications processing is performed in the module,
unloading the Maxiflex CPU module for the more
important system tasks such as control and SCADA
communications.
Through the use of network routing capability built into
the Conet/s protocol, this NIM may form part of a larger
network of networks, passing data seamlessly across
different network segments transparently to the
supervisory computer.
The M1580A has identical functionality to the M1592A
Single Serial NIM, but with the addition of a second
serial port. Each serial port can be used independently
with different protocols. The M1580A has a single
programming space exactly like the M1592A but with
access to both serial ports.
APPLICATIONS
•
Communicate with multiple devices that have a
serial port, and integrate the data from this
device into a DCS, PLC or SCADA system.
•
Use MODBUS to communicate with many third
party devices to integrate these devices into the
SCADA, DCS or PLC system
•
Point-to-Point Telemetry systems with analog
and digital data in both directions over a serial
link.
•
Use the Conet/s protocol for full duplex peer-topeer communications with RTU’s over a serial
link including fibre optic.
•
Remote I/O for SCADA software packages
incorporating third party devices.
•
Communicate over wide area networks,
integrating remote RTU’s into local systems.
