Do-more Designer Firmware     FAQs

BRX Series Stackable PLCs

The BRX platform is a versatile stackable Micro PLC system that combines powerful features in a compact, stand-alone footprint. The family consists of four Micro PLC Unit (MPU) form factor combinations are available (3 with built-in I/O) to provide strong system designs that fit application requirements exactly, keeping system costs to a minimum. The BRX platform is designed to be used as a stand-alone PLC or can be expanded using a wide variety of expansion module which easily snap onto the side of any BRX Micro PLC Unit (MPU) creating a sturdy and rugged PLC platform. BRX systems can also be expanded using remote base contollers. Look at the BX-DMIO for a dedicated Do-more RBC

 
BRX Micro PLC Features

Free Programming Software with Simulator  (Do-more Designer), and  there's also a free user manual

Do-more! DM1 Technology - Existing Do-more! projects can port over 100%.

Built-in Ethernet Port - EtherNet/IP, Modbus/TCP, MQTT, HTTP support (select modules).

Built-in Serial Port - RS232 or RS485 software selectable.

Pluggable Option Module (POM) Slot - Add additional serial port, Ethernet port, or USB port.

Built-in High Speed I/O - Up to 18 DC inputs and half of the DC outputs.

Built-in Analog I/O - Up to 6 I/O (on select models).

Expansion I/O - Any mix of discrete I/O and analog I/O modules, most BRX PLCs support 8 expansion I/O modules, but some only support 4, and some only 2, see below for details.

External Power Required - 12-24 VDC or 120-240 VAC.

NOTE: BRX CPUs can only be programmed with the new Do-more Designer software. DirectSOFT is not compatible with these CPUs.
