Note: This product has been superseded by the Model M1265B.

The MAXIFLEX A3e Maxilarm CPU is designed specifically for applications requiring Alarm Annunciator Functionality and Ethernet connectivity with PLC programming, offering industry standard IEC61131 programming capabilities combined with powerful industrial network communications features.

The CPU also supports 1ms time stamping at source with the use of the model M176xA Sequence of Events Input modules. This allows the Maxilarm CPU to deliver an Event Stream with 1millisecond resolution to a SCADA or Omni4000 Event Manager(CC018A) using the Conet OPC server (CC026A).

All local data is accessible through up to 64000 Data Interchange Registers in a single “Data Interchange Table (DIT)” for ease of communications. Up to four simultaneous Modbus/TCP and Conet/e connections can be made to this module.

All system configuration data and dynamic data can be read and written through this convenient table interface.

Conventional remote I/O systems can be implemented without the need for any programming, although the inclusion of all five IEC61131 programming languages allows complex local control functions to be performed.

Following the ISO OSI 7-layer model, this CPU includes a powerful inter-network routing capability for retrieving data from the corners of the factory in very large, geographically spread-out installations. This capability allows many dissimilar network types to be linked to create a seamless factory intranet, quite often without the need to layer special network cabling.

The A3 CPU automatically identifies the presence of I/O modules and performs I/O scanning of these modules, making this data available in the Data Interchange Table without needing to write a line of code.

Many other features such as a built-in real-time clock, battery backup for temporary dynamic data, and a MODBUS equipped RS232/485 serial port are standard in this product.
