Maxiflex Network Interface Module with two isolated RS232/485 Serial Port. Supports Conet/s, Modbus (Master/Slave; ASCII/RTU), or custom protocol (implemented in eziFORTH programming language on the module).

The M1580A Dual Serial Network Interface Module (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 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 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 4000 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 is the recommended for applications where mutiple Serial connections are required allowing two serial port connection from one module.
