For detailed information on DNP3 configuration and setup, refer to the Micro830, Micro850, and Micro870 Programmable Controllers Publication 2080-UM002.
The Micro 800 range is designed for straightforward installation and maintenance. A single software suite supports the entire product family, offering tailored control solutions for cost-effective, standalone machinery. Customers can select only the features they require and customise their system with plug-in modules to meet specific application demands.
Micro 810
These ultra-compact programmable logic controllers combine the functionality of smart relays with the advanced programming features of micro-PLCs. They include 12 I/O points, with 4 high-current relay outputs (8A), making them ideal for smart relay applications.
Micro 820
Designed for small standalone machines and remote automation tasks, these controllers feature a compact design and support up to 36 I/O points. They come with built-in Ethernet, a microSD slot for data logging and recipes, and analogue I/O capabilities, providing versatile communication and I/O options.
Micro 830
These controllers are built for standalone machine control applications requiring adaptable communication and I/O features. They support up to 88 I/O points, offering high-performance I/O, interrupt handling, and pulse train output (PTO) for motion control.
Micro 850
Ideal for larger standalone machine control applications, these controllers provide enhanced communication and I/O capabilities. They support up to 132 I/O points, featuring high-performance I/O, interrupts, PTO motion control, embedded Ethernet, and expandable I/O options.
Micro 870
Designed for large standalone machine control, these controllers offer extensive communication and I/O flexibility. They support up to 304 I/O points, with high-performance I/O, interrupts, PTO motion control, embedded Ethernet, and expandable I/O modules.
Micro 850 Expansion I/O
These expansion modules enhance the capabilities of the Micro 850 controllers by increasing the flexibility of I/O count and type. The modules attach securely to the controller and support both DIN rail and panel mounting.
Micro Plug-in Modules
These plug-in modules allow customers to customise their base controller to suit specific application needs. They extend the functionality of embedded I/O without increasing the controller's size and can enhance system capabilities through additional memory and clock modules.
Micro820 is a hybrid of Micro810 and Micro830 and Micro850. It has a:
Embedded Communications Capabilities
Micro810 (12-pt) - USB with 2080-USB-ADAPTER
Micro810/830 - USB and Non-isolated serial port
Micro850 - USB, Non-isolated serial port and Ethernet/IP
Micro870 - USB, Non-isolated serial port and Ethernet/IP
* Serial Port can not be used as a programming port in release 1
* USB port can be used only for programming
Expansion Comms via Plug-Ins
Isolated Serial Port (RS-232/485)
DeviceNet Master/Salve (Master not supported by Micro810).
Protocols
Micro800 serial ports supports Modbus RTU (master/slave), ASCII/binary.
Now a few Micr800 catalog numbers support DNP3, please refer to: QA33059 - DNP3 Protocol and Micro800. Key one Water waste water applications
Note: For protocols such as PCCC, DH-485, DF1 Radio Modem, refer to MicroLogix.
Micro800 has an embedded motion planner that is based upon the PLCopen Motion instruction set and behavior, which greatly simplifies motion by allowing the user to focus on the motion application instead of programming. The physical interface to the steppers and servo drives is the same as MicroLogix 1400 (24VDC Pulse), although Micro800 has both sink and source output models for different regions of the world.
Generally if you have an application that uses the broad communications capabilities of MicroLogix, you need to stay with MicroLogix. Micro800 is focusing on machine control and consequently focuses only on Modbus RTU Master/Slave for serial communications.
Current terminals blocks are all cage clamp. Are spring clamp type terminal blocks available?
For the controllers and expansion I/O with removable terminal blocks, spring clamp type is available but currently not from Rockwell Automation. All connectors are standard industrial connectors which can be sourced directly from the manufacturers' representative.
