- What are the power supply options to power the Micro800? How does the embedded power supply work for Micro810 and Micro830 controllers?
Micro810 has an embedded 120/240VAC, 12/24VDC (for transistor outputs only) or 12VDC power supply (for relay outputs). The Micro800 Power Supply 2080-PS120-240VAC can also be used with Micro810 24VDC controllers if additional 24VDC power is required for inputs, HMI, etc. up to 40W.
All Micro820, Micro830, Micro850 and Micro870 controllers are powered by an embedded 24VDC power supply. Generally for most machine control applications, the same 24VDC power supply as used for the 24VDC inputs and HMI can be used to power the controller for the lowest cost solution. For applications where 24VDC is not easily available or 24VDC is not properly regulated, a Micro800 Power Supply 2080-PS120-240VAC is available which optionally attaches to the left side of the Micro820/830/850/870 controllers and can supply enough power typically for the controller, up to 4 expansion I/O, Plug-ins, 24VDC inputs, and HMI up to 40W total.
- Is expansion I/O available for Micro800 controllers?
Yes. Micro850 currently supports up to 4 2085 expansion I/O and Micro870 support up to 8 modules with a power supply modules used after the 4th one. 2085 expansion I/O is used with the Micro850/870 for cases where more digital and analog I/O is required or where higher performance analog I/O is required. 32-pt 24VDC input modules, 4-ch RTD/TC and high resolution analog are available.
- What is a Plug-In module?
Plug-in modules are one of the key aspects of the Micro800 platform which is used to keep size and cost to a minimum while improving functionality. Users can customize the base Micro800 functionality by adding up to 5 plug-ins, such as: digital and analog I/O, communications, motion, and special functions such as add-on safety. In essence, the user can make his own special purpose PLC.
Plug-ins are different from 2085 expansion I/O in that Plug-ins are directly inserted into the Micro800 motherboard so high performance data rates, interrupts, and tight integration with the Micro800 execution engine are possible. The tradeoff is limited size, limited power dissipation, and non-isolated analog. 2085 Expansion I/O takes up additional space but excels in supporting low cost, higher density I/O, isolated analog, and higher performance and higher power modules which won't fit into a Plug-in.
- What Communication options are available?
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.
- Why is there no battery?
None of the Micro800 controllers require a battery to retain both the program and data. All controllers have flash memory to store the user program. For data, Micro810 uses a super capacitor to store the data for up to 1 week. Micro820/830/850/870 use FRAM memory technology to permanently store the data which eliminates the need for Lithium batteries, which can be a shipping and waste disposal problem. Eliminating batteries also simplifies maintenance and reduces downtime, which is especially important for remote RTU applications where maintenance is difficult.
The only battery is the small non-replaceable battery in the backup memory plug-in with Real Time Clock. The battery is used to run the RTC.
- Does Micro800 support PID instruction and does it have Auto-Tuning?
Yes. IPIDCONTROLLER instruction provides PID support with Auto-Tuning.
- Does Micro800 supports Motion Control using Pulse Train Outputs (PTO)? What's the difference between MicroLogix and Micro800 since MicroLogix also supports PTO?
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.
- I have an application today that uses MicroLogix 1100 and 1400 broad serial communications capabilities such as PCCC, DF1 Radio Modem, and DH-485. Can I use Micro800 instead?
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.
- What screwdriver is recommended?
If only one screwdriver is specified which works for controller, I/O, Plug-ins and Power Supply, then it should be a 2.5mm non-flared flat blade screwdriver with a shaft length of at least 65mm. If an electrician's screwdriver then minimum 15mm of the tip must be clear of shaft insulation. For optimum screwdriver performance for each product refer to the individual specifications of the product.
- What wire gauge is acceptable?
Refer to the installation manuals or wiring diagrams for each product. Generally for controllers, power supply and expansion I/O, up to 14 gauge is possible. For Plug-ins, up to 16 gauge is possible.
- Can I put more than 2 wires per terminal?
All terminal blocks are designed to hold more than 1 wire as long as it meets the specifications such as being stranded and maximum wire gauge. Generally it is recommended to only put 1 wire per terminal and to use ferrules for best performance. Ferrules also are available which can contain more than 1 wire.
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.
- What certifications does Micro800 have?
cULus CL1 DIV2 Hazardous (UL1508 and CSA specification certified though UL), CE, and C-Tick. Micro800 is Marine certification ready but it will take at 6-12months after release to receive the certification. Micro800 is ATEX ready but will not be available at launch. Contact your local Micro800 product manager if you require ATEX.
- What about 12VDC and 24VAC support for battery and building applications?
Power Supply: Micro810 has a 12VDC and 12/24VDC input power controllers available. For Micro810 24VAC and Micro830/850 24VAC and 12VDC power controllers, the 2080-PS12VDC-24VAC power supply will be available after initial launch.
Inputs: Generally most Micro800 24VDC inputs also support 12VDC (but please refer to installation manuals for exact specifications). Similarly 24VAC inputs are generally supported by 24DC inputs but the input filter time must be set to 8ms or higher.
- Is Removal Insertion Under Power (RIUP) supported for Plug-ins, I/O, etc.?
Generally RIUP is not supported for accessories such as Plug-ins and Expansion I/O. There are three exceptions: 2080-MEMBAK-RTC Plug-in for Micro830/850 series, 2080-MEMBAK-RTC2 modules for Micro830/850/870 series, and 2080-LCD for Micro810 series.
