NeoPAC SoftPLC models MLXP300-SN2-A1 Overview

The MLXP300-SN2-A1 combines a NeoPAC SoftPLC with an I/O block that includes digital inputs and outputs to create a compact, DIN-rail mount programmable automation controller suitable for small I/O count applications.


  • (1) GB RJ-45 Ethernet port (10/100/1000MB), user configurable protocols
  • (2) factory configurable option ports for A-B "blue-hose" (DH+, A-B RIO) and/or RS-485 (user-configurable protocols)
  • (2) USB Host communication ports
  • DIN-rail mount, approx 10-1/4 x 3-7/8 x 2-7/8 inches (WxHXD)
  • Simultaneously supports multiple user selectable Ethernet/serial protocols to hundreds of other vendor I/O products, devices and networks
  • 512MB RAM user memory for logic and up to 100M words data registers
  • 8GB on-board flash for application, web pages and data logging
  • Optional Micro SD flash for data logging - externally accessible
  • Extensive logic capability for data concentration, scaling, mapping between networks, and more
  • Alarm notification via email or text message, reports/logs can be sent via email attachments
  • Firmware options for a virtual HMI via an embedded web server or embedded Web Studio runtime
  • (12) 24VDC sinking digital inputs + (4) fast inputs that can also serve as 1 High-Speed Counter
  • (12) 24VDC sourcing digital outputs + (4) fast outputs that can serve as PTO/CFO/PWM

Ordering Information

  • Note: NeoPAC SoftPLC uses TOPDOC NexGen software for programming, configuration and troubleshooting. A free TOPDOC NexGen license is included with your first SoftPLC purchase!
  • All NeoPAC SoftPLCs include all supported serial and ethernet protocols as standard, configurable in any mix. If you desire isolated RS-485 communications, the port(s) must be factory installed - specify by selecting 1 or 2 RS485 options.
  • If you desire support for Allen-Bradley Data Highway Plus (DH+) or Remote I/O (RIO), the port(s) must be factory installed - specify by selecting 1 or 2 BH (blue hose) options.
  • Select any desired remote access and/or virtual HMI features. If the remote access connection will be other than wired Ethernet or WiFi/bluetooth, an external modem/interface is required. See Modems/Wireless for options, or contact SoftPLC to discuss TagWell cloud-based solutions and approved third-party interfaces.
  • The Size only applies if you are using ModbusTCP Master, Ethernet/IP, A-B RIO or DH+ protocols. Select the Lite (LT) version if you are not using these protocols.

    The Size determines the maximum number of ModbusTCP server connections, Ethernet/IP tags, force-able discrete I/O, and Allen-Bradley logical I/O racks supported (I and O addresses). The table below summarizes the available sizes:
