Disconnecting Main Power

WARNING: Explosion Hazard

Do not replace components, connect equipment, or disconnect equipment unless power has been switched off.

The main power disconnect switch should be located where operators and maintenance personnel have quick and easy access to it. In addition to disconnecting electrical power, all other sources of power (pneumatic and hydraulic) should be de-energized before working on a machine or process controlled by a controller.

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 11

Chapter 2 About Your Controller

Safety Circuits

WARNING: Explosion Hazard

Do not connect or disconnect connectors while circuit is live.

Circuits installed on the machine for safety reasons, like overtravel limit switches, stop push buttons, and interlocks, should always be hard-wired directly to the master control relay. These devices must be wired in series so that when any one device opens, the master control relay is de-energized, thereby removing power to the machine. Never alter these circuits to defeat their function. Serious injury or machine damage could result.

Power Distribution

There are some points about power distribution that you should know:

• The master control relay must be able to inhibit all machine motion by removing power to the machine I/O devices when the relay is deenergized. It is recommended that the controller remain powered even when the master control relay is de-energized.

• If you are using a DC power supply, interrupt the load side rather than the AC line power. This avoids the additional delay of power supply turn-off. The DC power supply should be powered directly from the fused secondary of the transformer. Power to the DC input and output circuits should be connected through a set of master control relay contacts.

Periodic Tests of Master Control Relay Circuit

Any part can fail, including the switches in a master control relay circuit. The failure of one of these switches would most likely cause an open circuit, which would be a safe power-off failure. However, if one of these switches shorts out, it no longer provides any safety protection. These switches should be tested periodically to assure they will stop machine motion when needed.

Power Considerations

12 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013

The following explains power considerations for the micro controllers.

About Your Controller Chapter 2

Isolation Transformers

You may want to use an isolation transformer in the AC line to the controller. This type of transformer provides isolation from your power distribution system to reduce the electrical noise that enters the controller and is often used as a stepdown transformer to reduce line voltage. Any transformer used with the controller must have a sufficient power rating for its load. The power rating is expressed in volt-amperes (VA).

Power Supply Inrush

During power-up, the Micro800 power supply allows a brief inrush current to charge internal capacitors. Many power lines and control transformers can supply inrush current for a brief time. If the power source cannot supply this inrush current, the source voltage may sag momentarily.

The only effect of limited inrush current and voltage sag on the Micro800 is that the power supply capacitors charge more slowly. However, the effect of a voltage sag on other equipment should be considered. For example, a deep voltage sag may reset a computer connected to the same power source. The following considerations determine whether the power source must be required to supply high inrush current:

• The power-up sequence of devices in a system.

• The amount of the power source voltage sag if the inrush current cannot be

supplied.

• The effect of voltage sag on other equipment in the system.

If the entire system is powered-up at the same time, a brief sag in the power source voltage typically will not affect any equipment.

Loss of Power Source

The optional Micro800 AC power supply is designed to withstand brief power losses without affecting the operation of the system. The time the system is operational during power loss is called program scan hold-up time after loss of power. The duration of the power supply hold-up time depends on power consumption of controller system, but is typically between 10 milliseconds and 3 seconds.

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 13

Chapter 2 About Your Controller

TIP

Input States on Power Down

The power supply hold-up time as described above is generally longer than the turn-on and turn-off times of the inputs. Because of this, the input state change from “On” to “Off” that occurs when power is removed may be recorded by the processor before the power supply shuts down the system. Understanding this concept is important. The user program should be written to take this effect into account.

Other Types of Line Conditions

Occasionally the power source to the system can be temporarily interrupted. It is also possible that the voltage level may drop substantially below the normal line voltage range for a period of time. Both of these conditions are considered to be a loss of power for the system.

Preventing Excessive Heat

Master Control Relay

For most applications, normal convective cooling keeps the controller within the specified operating range. Ensure that the specified temperature range is maintained. Proper spacing of components within an enclosure is usually sufficient for heat dissipation.

In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure. In this case, place blower fans inside the enclosure to assist in air circulation and to reduce “hot spots” near the controller.

Additional cooling provisions might be necessary when high ambient temperatures are encountered.

Do not bring in unfiltered outside air. Place the controller in an enclosure to protect it from a corrosive atmosphere. Harmful contaminants or dirt could cause improper operation or damage to components. In extreme cases, you may need to use air conditioning to protect against heat buildup within the enclosure.

A hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint. Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens, the master control relay is de-energized. This removes power to input and output device circuits. Refer to the figures on pages 17 and 18.

14 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013

About Your Controller Chapter 2

TIP

WARNING: Never alter these circuits to defeat their function

since serious injury and/or machine damage could result.

If you are using an external DC power supply, interrupt the DC output side rather than the AC line side of the supply to avoid the additional delay of power supply turn-off.

The AC line of the DC output power supply should be fused.

Connect a set of master control relays in series with the DC power supplying the input and output circuits.

Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it. If you mount a disconnect switch inside the controller enclosure, place the switch operating handle on the outside of the enclosure, so that you can disconnect power without opening the enclosure.

Whenever any of the emergency-stop switches are opened, power to input and output devices should be removed.

When you use the master control relay to remove power from the external I/O circuits, power continues to be provided to the controller’s power supply so that diagnostic indicators on the processor can still be observed.

The master control relay is not a substitute for a disconnect to the controller. It is intended for any situation where the operator must quickly de-energize I/O devices only. When inspecting or installing terminal connections, replacing output fuses, or working on equipment within the enclosure, use the disconnect to shut off power to the rest of the system.

Do not control the master control relay with the controller. Provide the operator with the safety of a direct connection between an emergencystop switch and the master control relay.

Using Emergency-Stop Switches

When using emergency-stop switches, adhere to the following points:

• Do not program emergency-stop switches in the controller program. Any emergency-stop switch should turn off all machine power by turning off the master control relay.

• Observe all applicable local codes concerning the placement and labeling of emergency-stop switches.

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 15

Chapter 2 About Your Controller

TIP

• Install emergency-stop switches and the master control relay in your system. Make certain that relay contacts have a sufficient rating for your application. Emergency-stop switches must be easy to reach.

• In the following illustration, input and output circuits are shown with MCR protection. However, in most applications, only output circuits require MCR protection.

The following illustrations show the Master Control Relay wired in a grounded system.

In most applications input circuits do not require MCR protection; however, if you need to remove power from all field devices, you must include MCR contacts in series with input power wiring.

50.8 mm (2 in.) of space on all sides. This provides ventilation and electrical isolation. If optional accessories/modules are attached to the controller, such as the power supply 2080-PS120-240VAC or expansion I/O modules, make sure that there is 50.8 mm (2 in.) of space on all sides after attaching the optional parts.

DIN Rail Mounting

The module can be mounted using the following DIN rails: 35 x 7.5 x 1 mm and 35 x 15 mm (EN 50 022 - 35 x 7.5 and EN 50 022 - 35 x 15).

For environments with greater vibration and shock concerns, use the panel mounting method, instead of DIN rail mounting.

Before mounting the module on a DIN rail, use a flat-blade screwdriver in the DIN rail latch and pry it downwards until it is in the unlatched position.

1. Hook the top of the DIN rail mounting area of the controller onto the DIN rail, and then press the bottom until the controller snaps onto the DIN rail.

2. Push the DIN rail latch back into the latched position. Use DIN rail end anchors (Allen-Bradley part number 1492-EAJ35 or 1492-EAHJ35) for vibration or shock environments.

To remove your controller from the DIN rail, pry the DIN rail latch downwards until it is in the unlatched position.

Panel Mounting

The preferred mounting method is to use four M4 (#8) screws per module. Hole spacing tolerance: ±0.4 mm (0.016 in.).

Follow these steps to install your controller using mounting screws.

1. Place the controller against the panel where you are mounting it. Make sure the controller is spaced properly.

2. Mark drilling holes through the mounting screw holes and mounting feet then remove the controller.

3. Drill the holes at the markings, then replace the controller and mount it. Leave the protective debris strip in place until you are finished wiring the controller and any other devices.

Wiring Requirements and Recommendation

WARNING: Before you install and wire any device, disconnect power to

the controller system.

WARNING: Calculate the maximum possible current in each power and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. Current above the maximum ratings may cause wiring to overheat, which can cause damage. United States Only: If the controller is installed within a potentially hazardous environment, all wiring must comply with the requirements stated in the National Electrical Code 501-10 (b).

• Allow for at least 50 mm (2 in.) between I/O wiring ducts or terminal strips and the controller.

• Route incoming power to the controller by a path separate from the device wiring. Where paths must cross, their intersection should be perpendicular.

Do not run signal or communications wiring and power wiring in the same conduit. Wires with different signal characteristics should be routed by separate paths.

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 25

Chapter 4 Wire Your Controller

• Separate wiring by signal type. Bundle wiring with similar electrical characteristics together.

• Separate input wiring from output wiring.

• Label wiring to all devices in the system. Use tape, shrink-tubing, or other

dependable means for labeling purposes. In addition to labeling, use colored insulation to identify wiring based on signal characteristics. For example, you may use blue for DC wiring and red for AC wiring.

Because of the potentially high current surges that occur when switching inductive load devices, such as motor starters and solenoids, the use of some type of surge suppression to protect and extend the operating life of the controllers output contacts is required. Switching inductive loads without surge suppression can significantly reduce the life expectancy of relay contacts. By adding a suppression device directly across the coil of an inductive device, you prolong the life of the output or relay contacts. You also reduce the effects of voltage transients and electrical noise from radiating into adjacent systems.

A surge suppressor can also be used.

The following diagram shows an output with a suppression device. We recommend that you locate the suppression device as close as possible to the load device.

If the outputs are DC, we recommend that you use an 1N4004 diode for surge suppression, as shown below. For inductive DC load devices, a diode is suitable. A 1N4004 diode is acceptable for most applications. A surge suppressor can also be used. See Recommended Surge Suppressors

on page28. As shown below, these

surge suppression circuits connect directly across the load device.

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 27

Suitable surge suppression methods for inductive AC load devices include a varistor, an RC network, or an Allen-Bradley surge suppressor, all shown below. These components must be appropriately rated to suppress the switching

Serial Port Terminal Block

This section contains some relevant information about minimizing electrical noise and also includes some wiring examples.

Wire Your Controller Chapter 4

Minimize Electrical Noise

Because of the variety of applications and environments where controllers are installed and operating, it is impossible to ensure that all environmental noise will be removed by input filters. To help reduce the effects of environmental noise, install the Micro800 system in a properly rated (for example, NEMA) enclosure. Make sure that the Micro800 system is properly grounded.

A system may malfunction due to a change in the operating environment after a period of time. We recommend periodically checking system operation, particularly when new machinery or other noise sources are installed near the Micro800 system.

Analog Channel Wiring Guidelines

Consider the following when wiring your analog channels:

• The analog common (-DC24) is not electrically isolated from the system, and is connected to the power supply common.

• Analog channels are not isolated from each other.

• Use Belden cable #8761, or equivalent, shielded wire.

• Under normal conditions, the drain wire (shield) should be connected to

the metal mounting panel (earth ground). Keep the shield connection to earth ground as short as possible.

• To ensure optimum accuracy for voltage type inputs, limit overall cable impedance by keeping all analog cables as short as possible. Locate the I/O system as close to your voltage type sensors or actuators as possible.

Minimize Electrical Noise on Analog Channels

Inputs on analog channels employ digital high-frequency filters that significantly reduce the effects of electrical noise on input signals. However, because of the variety of applications and environments where analog controllers are installed and operated, it is impossible to ensure that all environmental noise will be removed by the input filters.

Several specific steps can be taken to help reduce the effects of environmental noise on analog signals:

• install the Micro800 system in a properly rated enclosure, for example, NEMA/IP. Make sure that the shield is properly grounded.

• use Belden cable #8761 for wiring the analog channels, making sure that the drain wire and foil shield are properly earth grounded.

• route the Belden cable separately from any AC wiring. Additional noise immunity can be obtained by routing the cables in grounded conduit.

Grounding Your Analog Cable

Use shielded communication cable (Belden #8761). The Belden cable has two signal wires (black and clear), one drain wire, and a foil shield. The drain wire and foil shield must be grounded at one end of the cable.

Do not ground the drain wire and foil shield at both ends of the cable.

Calculate for Thermistor Resistance

While connecting Analog input to thermistor as shown in previous diagram, calculate input voltage using the following equation:

Where: Vi = Voltage input (±5% without calibration; ±2% with calibration) Ri = Resistance input (14.14 KΩ ±2%) Rt = Thermistor resistance (10 KΩ Thermistor is recommended) Vref = 10V ±0.5V

To calculate for thermistor resistance, use the following equation.

Micro820 controllers support 10 KΩ type thermistors. In order to get the best results, the system must be calibrated.

Calibrate Thermistor

1. Connect a resistor (10 KΩ is recommended) across Vref and Analog Input 00 of your Micro820 controller following the diagram, Analog input

to thermistors on page34. The resistor is measured as Ri using a precision

multimeter.

2. Calculate the ideal counts (C1) for resistor (Ri) following this equation: C1 = 14.14 KΩ / (14.14 KΩ + Ri) * 4095

3. Read the actual counts (C2) of Analog Input 00 from Connected Components Workbench.

4. Calculate for calibration Gain. Gain = C1/C2

For example : If Ri is measured as 10.00 KΩ, then C1 = 14.14 / (14.14 + 10.00) * 4095 = 2399 counts; C2 is read from Connected Components Workbench as 2440; so Gain = 2399/2440 = 98% .

This chapter also describes how the controller establishes communication with the appropriate network. Topics include:

Topic Page

Supported Communication Protocols 37

Use Modems with Micro800 Controllers 41

Configure Serial Port 42

Configure Ethernet Settings 48

The Micro820 controllers have the following embedded communication channels:

• a non-isolated RS232/RS485 combo port

• RJ45 Ethernet port

Micro820 controllers support the following communication protocols through the embedded RS232/RS485 serial port as well as any installed serial port plug-in modules:

• Modbus RTU Master and Slave

• CIP Serial Client/Server (RS232 only)

• ASCII

In addition, the embedded Ethernet communication channel allows your Micro820 controller to be connected to a local area network for various devices providing 10 Mbps/100 Mbps transfer rate. Micro820 controllers support the following Ethernet protocols:

• EtherNet/IP Client/Server

• Modbus/TCP Client/Server

• DHCP Client

Modbus RTU

Modbus is a half-duplex, master-slave communications protocol. The Modbus network master reads and writes bits and registers. Modbus protocol allows a

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 37

Chapter 5 Communication Connections

TIP

single master to communicate with a maximum of 247 slave devices. Micro800 controllers support Modbus RTU Master and Modbus RTU Slave protocol. For more information on configuring your Micro800 controller for Modbus protocol, refer to the Connected Components Workbench Online Help. For more information about the Modbus protocol, refer to the Modbus Protocol Specifications (available from http://www.modbus.org

See Modbus Mapping for Micro800 on page 249

for information on Modbus mapping. To configure the Serial port as Modbus RTU, see Configure Modbus

RTU on page 45.

Use MSG_MODBUS instruction to send Modbus messages over serial port.

Modbus/TCP Client/Server

The Modbus/TCP Client/Server communication protocol uses the same Modbus mapping features as Modbus RTU, but instead of the Serial port, it is supported over Ethernet. Modbus/TCP Server takes on Modbus Slave features on Ethernet.

The Micro820 controller supports up to 16 simultaneous Modbus TCP Client connections and 16 simultaneous Modbus TCP Server connections.

No protocol configuration is required other than configuring the Modbus mapping table. For information on Modbus mapping, see Modbus Mapping for

Micro800 on page 249.

Use MSG_MODBUS2 instruction to send Modbus TCP message over Ethernet port.

CIP Symbolic Client/Server

CIP Symbolic is supported by any CIP compliant interface including Ethernet (EtherNet/IP) and Serial Port (CIP Serial). This protocol allows HMIs to easily connect to the Micro820 controller.

CIP Serial, supported on the Micro820 controller, makes use of DF1 Full Duplex protocol, which provides point-to-point connection between two devices.

The Micro800 controllers support the protocol through RS232 connection to external devices, such as computers running RSLinx Classic software, PanelView Component terminals (firmware revisions 1.70 and above), or other controllers that support CIP Serial over DF1 Full-Duplex, such as ControlLogix and CompactLogix controllers that have embedded serial ports.

ASCII

ASCII provides connection to other ASCII devices, such as bar code readers, weigh scales, serial printers, and other intelligent devices. You can use ASCII by configuring the embedded or any plug-in serial RS232 or RS485 port for the ASCII driver. Refer to the Connected Components Workbench Online Help for more information.

CIP Communications Pass-thru

To configure the serial port for ASCII, see Configure ASCII

on page 47.

The Micro820 controllers support pass-thru on any communications port that supports Common Industrial Protocol (CIP). The maximum number of supported hops is one. A hop is defined to be an intermediate connection or communications link between two devices – in Micro800, this is through EtherNet/IP or CIP Serial.

IMPORTANT

Program Execution in Micro800

This section provides a brief overview of running or executing programs with a Micro800 controller.

This section generally describes program execution in Micro800 controllers. Certain elements may not be applicable or true in certain models (for example, Micro820 does not support PTO motion control).

Overview of Program Execution

A Micro800 cycle or scan consists of reading inputs, executing programs in sequential order, updating outputs and performing housekeeping (datalog, recipe, communications).

Program names must begin with a letter or underscore, followed by up to 127 letters, digits or single underscores. Use programming languages such as ladder logic, function block diagrams and structured text.

Up to 256 programs may be included in a project, depending on available controller memory. By default, the programs are cyclic (executed once per cycle or scan). As each new program is added to a project, it is assigned the next consecutive order number. When you start up the Project Organizer in Connected Components Workbench, it displays the program icons based on this order. You can view and modify an order number for a program from the program’s properties. However, the Project Organizer does not show the new order until the next time the project is opened.

The Micro800 controller supports jumps within a program. Call a subroutine of code within a program by encapsulating that code as a User Defined Function Block (UDFB). Although a UDFB can be executed within another UDFB, a maximum nesting depth of five is supported. A compilation error occurs if this is exceeded.

Alternatively, you can assign a program to an available interrupt and have it executed only when the interrupt is triggered. A program assigned to the User Fault Routine runs once just prior to the controller going into Fault mode.

In addition to the User Fault Routine, Micro800 controllers also support two Selectable Timed Interrupts (STI). STIs execute assigned programs once every set point interval (1…65535 ms).

The Global System Variables associated with cycles/scans are:

• __SYSVA_CYCLECNT – Cycle counter

4. Housekeeping (datalog,

(1) Program Organizational Unit.

• __SYSVA_TCYCURRENT – Current cycle time

• __SYSVA_TCYMAXIMUM – Maximum cycle time since last start.

Execution Rules

This section illustrates the execution of a program. The execution follows four main steps within a loop. The loop duration is a cycle time for a program.

Controller Load and Performance Considerations

When a cycle time is specified, a resource waits until this time has elapsed before starting the execution of a new cycle. The POUs execution time varies depending on the number of active instructions. When a cycle exceeds the specified time, the loop continues to execute the cycle but sets an overrun flag. In such a case, the application no longer runs in real time.

When a cycle time is not specified, a resource performs all steps in the loop then restarts a new cycle without waiting.

Within one program scan cycle, the execution of the main steps (as indicated in the Execution Rules diagram) could be interrupted by other controller activities which have higher priority than the main steps. Such activities include,

1. User Interrupt events, including STI, EII, and HSC interrupts (when applicable);

2. Communication data packet receiving and transmitting;

3. PTO Motion engine periodical execution (if supported by the controller).

When one or several of these activities occupy a significant percentage of the Micro800 controller execution time, the program scan cycle time will be prolonged. The Watchdog timeout fault (0xD011) could be reported if the impact of these activities is underestimated, and the Watchdog timeout is set

52 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013

Program Execution in Micro800 Chapter 6

marginally. The Watchdog setting defaults to 2 s and generally never needs to be changed.

Periodic Execution of Programs

For applications where periodic execution of programs with precise timing is required, such as for PID, it is recommended that STI (Selectable Timed Interrupt) be used to execute the program. STI provides precise time intervals.

It is not recommended that the system variable __SYSVA_TCYCYCTIME be used to periodically execute all programs as this also causes all communication to execute at this rate.

System Variable for Programmed Cycle Time

WARNING: Communication timeouts may occur if programmed cycle

time is set too slow (for example, 200 ms) to maintain communications.

Power Up and First Scan

Variable Type Description

__SYSVA_TCYCYCTIME TIME Programmed cycle time.

Note: Programmed cycle time only accepts values in multiples of 10 ms. If the entered value is not a multiple of 10, it will be rounded up to the next multiple of 10.

On firmware revision 2 and later, all digital output variables driven by the I/O scan gets cleared on powerup and during transition to RUN mode.

Two system variables are also available from revision 2 and later.

System Variables for Scan and Powerup on Firmware Release 2 and later

Variable Type Description

_SYSVA_FIRST_SCAN BOOL First scan bit.

Can be used to initialize or reset variables immediately after every transition from Program to Run mode.

Note: True only on first scan. After that, it is false.

_SYSVA_POWER_UP_BIT BOOL Powerup bit.

Can be used to initialize or reset variables immediately after download from Connected Components Workbench or immediately after being loaded from memory backup module (for example, microSD card).

Note:True only on the first scan after a powerup, or running a new ladder for the first time.

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 53

Chapter 6 Program Execution in Micro800

Variable Retention

Micro830 and Micro850 controllers retain all user-created variables after a power cycle, but the variables inside instances of instructions are cleared. For example: A user created variable called My_Timer of Time data type will be retained after a power cycle but the elapsed time (ET) within a user created timer TON instruction will be cleared.

Unlike Micro830/Micro850 controllers, Micro810 and Micro820 controllers can only retain a maximum of 400 bytes of user-created variable values. This means that after a power cycle, global variables are cleared or set to initial value, and only 400 bytes of user-created variable values are retained. Retained variables can be checked at the global variable page.

Memory Allocation

Depending on base size, available memory on Micro800 controllers are shown in the table below.

Memory Allocation for Micro800 Controllers

Attribute 10/16-point 20-point 24- and 48-points

Program steps

Data bytes 8 KB 20 KB 20 KB

(1) Estimated Program and Data size are “typical” – program steps and variables are created dynamically.

1 Program Step = 12 data bytes.

(1)

4 K 10 K 10 K

These specifications for instruction and data size are typical numbers. When a project is created for Micro800, memory is dynamically allocated as either program or data memory at build time. This means that program size can exceed the published specifications if data size is sacrificed and vice versa. This flexibility allows maximum usage of execution memory. In addition to the user defined variables, data memory also includes any constants and temporary variables generated by the compiler at build time.

The Micro800 controllers also have project memory, which stores a copy of the entire downloaded project (including comments), as well as configuration memory for storing plug-in setup information, and so on.

Guidelines and Limitations for Advanced Users

54 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013

Here are some guidelines and limitations to consider when programming a Micro800 controller using Connected Components Workbench software:

Program Execution in Micro800 Chapter 6

UDFB1

UDFB2

UDFB3

UDFB4

UDFB5

• Each program/POU can use up to 64 Kb of internal address space. It is recommended that you split large programs into smaller programs to improve code readability, simplify debugging and maintenance tasks.

• A User Defined Function Block (UDFB) can be executed within another UDFB, with a limit of five nested UDFBs. Avoid creating UDFBs with references to other UDFBs, as executing these UDFBs too many times may result in a compile error.

Example of Five Nested UDFBs

• Structured Text (ST) is much more efficient and easier to use than Ladder Logic, when used for equations. if you are used to using the RSLogix 500 CPT Compute instruction, ST combined with UDFB is a great alternative. As an example, for an Astronomical Clock Calculation, Structured Text uses 40% less Instructions.

Display_Output LD: Memory Usage (Code) : 3148 steps Memory Usage (Data) : 3456 bytes

Display_Output ST: Memory Usage (Code) : 1824 steps Memory Usage (Data) : 3456 bytes

• You may encounter an Insufficient Reserved Memory error while downloading and compiling a program over a certain size. One workaround is to use arrays, especially if there are many variables.

TIP

Controller Security

Micro800 security generally has two components:

• Exclusive Access which prevents simultaneous configuration of the controller by two users

• Controller Password Protection which secures the Intellectual Property contained within the controller and prevents unauthorized access

Exclusive Access

Password Protection

Exclusive access is enforced on the Micro800 controller regardless of whether the controller is password-protected or not. This means that only one Connected Components Workbench session is authorized at one time and only an authorized client has exclusive access to the controller application. This ensures that only one software session has exclusive access to the Micro800 applicationspecific configuration.

Exclusive access is enforced on Micro800 firmware. When a Connected Components Workbench user connects to a Micro800 controller, the controller is given exclusive access to that controller.

By setting a password on the controller, a user effectively restricts access to the programming software connection of the controller to software sessions that can supply the correct password. Essentially, Connected Components Workbench operations such as upload and download are prevented if the controller is secured with a password and the correct password is not provided.

Micro800 controllers are shipped with no password but a password can be set through the Connected Components Workbench software (using firmware revision 2 or later).

The controller password is also backed up to the memory backup module (that is, 2080-MEMBAK-RTC for Micro830 and Micro850; 2080-LCD for Micro810; and microSD card for Micro820).

For instructions on how to set, change, and clear controller passwords, see Configure Controller Password

Compatibility

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 57

The Controller Password feature is supported on:

• Connected Components Workbench revision 2 and later

on page 128.

Chapter 7 Controller Security

• Micro800 controllers with at least revision 2 firmware

For users with earlier versions of the software and/or hardware, refer to the compatibility scenarios below.

Connected Components Workbench revision 1 with Micro800 controller firmware revision 2 and later

Connection to a Micro800 controller with firmware revision 2 using an earlier version of the Connected Components Workbench software (revision 1) is possible and connections will be successful. However, the software will not be able to determine whether the controller is locked or not.

If the controller is not locked, access to the user application will be allowed, provided the controller is not busy with another session. If the controller is locked, access to the user application will fail. Users will need to upgrade to revision 2 of the Connected Components Workbench software.

Connected Components Workbench revision 2 and later with Micro800 controller firmware revision 1

Work with a Locked Controller

Connected Components Workbench revision 2 is capable of "discovering" and connecting to Micro800 controllers with firmware revision earlier than revision 2 (that is, not supporting the Controller Password feature). However, the Controller Password feature will not be available to these controllers. The user will not be able see interfaces associated with the Controller Password feature in the Connected Components Workbench session.

Users are advised to upgrade the firmware. See Flash Upgrade Your Micro800

Firmware on page 121 for instructions.

The following workflows are supported on compatible Micro800 controllers (firmware revision 2) and Connected Components Workbench software revision 2.

Controller Security Chapter 7

Recover from a Lost Password

If the controller is secured with a password and the password has been lost, then it is impossible to access the controller using the Connected Components Workbench software.

To recover, the controller must be set to Program Mode using the keyswitch for Micro830 and Micro850 controllers, the 2080-LCD for Micro810 controllers, or the 2080-REMLCD for the Micro820. Then, ControlFlash can be used to update the controller firmware, which also clears the controller memory.

ATTENTION: The project in the controller will be lost but a new project can be downloaded.

The 2080-REMLCD module is IP65-rated and can be mounted through the front panel or on the same DIN rail as the Micro820 controller.

It has two modes of operation:

• USB Mode

• Text Display Mode – I/O Status and Main Menu operations (for example, change to

RUN mode)

– Optional user-defined screens (using the LCD_REM instructions)

In USB mode, the Remote LCD module acts as a USB pass-through for Connected Components Workbench. The Remote LCD module automatically enters USB mode when traffic is detected.

64 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013

For example:

1. Remote LCD is in text display mode showing the I/O Status screen by default.

2. The user connects a USB cable between the PC and the Remote LCD.

3. Remote LCD is automatically detected by the PC as a USB device and the

Remote LCD automatically goes to USB mode.

4. I/O Status screen is no longer shown. The user is now able to download program over USB using Connected Components Workbench.

5. When the USB cable is disconnected and no traffic is detected for 30 seconds, the Remote LCD automatically goes back to text display mode showing the I/O Status screen.

Default startup screen

Using the USB port is convenient when accessing the controller from the front of the cabinet without opening the door and when the IP address is unknown. For larger programs, it is recommended to use USB port through the Remote LCD to set the IP address and then use Ethernet to download. Ethernet is faster due to limitations of the USB to serial conversion.

Text Display Mode

In text display mode, you are either in I/O Status, Main Menu, or executing Remote LCD instructions.

Startup Screen

On powerup, the Remote LCD module powers up with a splash screen that displays "Initializing". Then, it displays "Connecting to Controller" until the connection is established. The controller then displays the startup screen for 3 seconds by default or user-defined duration after the connection is established.

The user can customize this startup screen through Connected Components Workbench. The controller displays the default startup screen at powerup when the customized startup screen is blank.

Overview

The last section provides quickstart projects for the datalog and recipe functions.

Micro820 controllers support microSD cards for the following purposes:

• Project backup and restore

• Datalog and Recipe

For optimum performance, regularly check available space on your microSD card and ensure that the card is exclusively used for the Micro800 controller and no unnecessary files are present. Regularly delete old datalog files and directories.

Do not remove the microSD card or power down while operations such as upload, download, delete, search, backup and restore are ongoing to prevent data loss. A blinking SD status LED indicates that these operations are ongoing.

To prevent data loss, recipe and datalog function blocks must indicate Idle status before microSD card is removed.

Project Backup and Restore

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 73

Project backup and restore on Micro820 controllers are mainly supported through the microSD card. Both backup and restore can be initiated or manually

triggered and configured through the Connected Components Workbench, the 2080-REMLCD module, and the ConfigMeFirst.txt file in the microSD card.

Backup and restore can only occur when the controller is in PROGRAM mode. On controller powerup, restore automatically occurs if the Load Always or Load on Memory Error option has been configured in Connected Components Wo r k b e n c h .

To learn about restore and backup using the 2080-REMLCD module, see

Using the Micro800 Remote LCD

on page 63.

To learn about restore and backup using the Connected Components Workbench, refer to the software Online Help.

For Micro800 controllers that support microSD cards, IP protection of user project can only be achieved through the POU password protection mechanism in Connected Components Workbench (Developer Edition) and NOT via Controller Lock feature.

The microSD card stores the controller password in encrypted format. When the password is mismatched, the contents of the microSD card is not restored on the controller.

Backup and restore can be configured to trigger through the following ways:

Using microSD Cards Chapter 9

Backup and Restore Directory Structure

When a user project is backed up, a subdirectory named Micro820/USERPRJ is created on the microSD card. The folder name takes the name of the project specified in the General Page in Connected Components Workbench, which is Micro820 by default. However, if the ConfigMeFirst.txt file specifies a different subdirectory (example: MyProject), the project is backed up to that directory. See

General Configuration Rules in ConfigMeFirst.txt

on page 77.

Project restore is done from the subdirectory specified in ConfigMeFirst.txt file or the Micro820/USERPRJ default folder, if none is specified in the ConfigMeFirst.txt file. The user needs to ensure that the directory is populated with correct contents before restoring.

The ConfigMeFirst.txt file is a configuration file stored on the microSD card that the user can optionally create to customize backup, restore, recipe and datalog directories. The following sections include information on how to configure the ConfigMeFirst.txt properly.

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 75

Chapter 9 Using microSD Cards

IMPORTANT

The Micro800 controller reports a major fault when project backup does not succeed because the memory card size is exceeded.

Powerup Settings in ConfigMeFirst.txt

On powerup, the Micro820 controller reads and carries out configuration settings described in the ConfigMeFirst.txt file, as shown in the following table.

ConfigMeFirst.txt Configuration Settings

Setting Description

[PM] Power up and switch to PROGRAM mode.

[CF] Power up and attempt to clear fault.

[ESFD] Embedded Serial Factory Defaults.

Power up and revert embedded serial comms to factory defaults.

[IPA = xxx.xxx.xxx.xxx] Power up and set IP address to xxx (must be numbers only).

[SNM = xxx.xxx.xxx.xxx] Power up and set subnet mask to xxx (must be numbers only).

[GWA = xxx.xxx.xxx.xxx] Power up and set gateway address to xxx (must be numbers only).

[BKD = My Proj 1] Power up and save the controller project into backup directory,

My Proj 1\USERPRJ. Require extra power cycle to clear existing fault first using [CF] setting or other means.

[RSD = MyProj2] Power up and read the project from restore directory MyProj2\USERPRJ

into controller. Require extra power cycle to clear existing fault first using [CF] setting or other means. This setting overwrites UPD (or its default) load always or load on error restore function.

[UPD = My Proj] For normal usage of backup and restore (that is, through Connected

Components Workbench, 2080-REMLCD, Load Always, or Load on Memory Error settings), set the user project directory name. For example, My Proj, during powerup or when the microSD card is inserted.

This directory is also used by data logging and recipe function.

[END] End of setting.

This setting is always required even when the ConfigMeFirst.txt file does not contain any other setting. The SD LED goes off when this setting is not present.

Directory Settings

• If no directory has been specified in the ConfigMeFirst.txt file, then

backup and restore will occur in the controller name directory (Micro820/USERPRJ, by default).

• If [UPD] is configured in the ConfigMeFirst.txt file, then backup and

restore will occur in the [UPD] directory specified.

• [BKD] setting is implemented even when the controller is locked or

password protected.

• [BKD] directory is automatically created if it does not yet exist.

76 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013

IMPORTANT

Powerup Network Parameter Settings

• [IPA], [SNM] and [GWA] follow the general IP configuration rules.

• [IPA], when set in ConfigMeFirst.txt, should always be configured

with a valid [SNM] and vice versa.

• When optional [GWA] setting is used, make sure that [IPA] and [SNM]

settings are also present in ConfigMeFirst.txt.

• The [ESFD], [IPA], [SNM], and [GWA] settings overwrite the respective

communication settings from project restore due to [RSD], Load Always or Load on Memory Error.

Sample ConfigMeFirst.txt File

Using microSD Cards Chapter 9

General Configuration Rules in ConfigMeFirst.txt

• All settings must be in upper case and enclosed in brackets [ ].

• Each line must contain only one setting.

• Settings must always appear first in a line.

• Comments are started with the # symbol.

• No action related to the setting will be carried out when the setting does

not exist, or a # symbol appears before the setting (example, #[PM]).

ConfigMeFirst.txt Errors

The SD status LED goes off when the microSD card is inserted during PROGRAM or RUN mode (or on powerup) and the ConfigMeFirst.txt file is either unreadable or invalid. The ConfigMeFirst.txt file will be invalid when it has the following errors:

• unrecognized setting (that is, the first three configuration rules have not been followed),

• the setting parameters after the = symbol is invalid, does not exist, or out of range,

• the same setting exists twice or more,

• one or more non-setting characters exist within the same bracket,

• space in between setting characters (example, [P M]), or

Rockwell Automation Publication 2080-UM005A-EN-E - December 2013 77

Chapter 9 Using microSD Cards

IMPORTANT

• space in between IP address, subnet mask, and gateway address (for example, xxx. x xx.xxx.xxx)

• [END] setting does not exist (even if there are no other settings in the configuration file).

The microSD card becomes unusable until the ConfigMeFirst.txt file becomes readable or the errors are corrected.

Datalog

The datalogging feature allows you to capture global and local variables with timestamp from the Micro800 controller into the microSD card. You can retrieve the recorded datasets on the microSD card by reading the contents of the microSD card through a card reader or by doing an upload through the Connected Components Workbench software.

A maximum number of 10 datasets is supported for a Micro820 program. Each dataset can contain up to 128 variables, with a maximum of four (4) data string variables per dataset. String variables can have a maximum of 252 characters. All datasets are written to the same file. For more information on how datalogs are stored on the microSD card, see the Datalog Directory Structure

on page 79.

Micro820 controllers typically support 10 MB of datalog per day.

You can retrieve datalog files from the microSD card using a card reader or by uploading the datalogs through Connected Components Workbench.

Uploading datalog files in PROGRAM mode is recommended for optimum performance and to prevent file access conflict. For example, if the datalog instruction is executing, Connected Components Workbench will not upload the last datalog file.

See the sample quickstart project to get you started on the Datalog feature, on

page 87.

Datalog execution time depends on the user application and its complexity. Users are advised to datalog once a minute for typical applications. Note that housekeeping takes at least 5 ms per program scan. See Program Execution in Micro800 information on program scan and execution rules and sequence.

See also Datalog – Data Payload vs. Performance Time

Note that in cases where there are simultaneous RCP and DLG function block execution or uploads/downloads/searches, the activities are queued up and handled one by one by the program scan. Users will notice a slowdown in performance in these cases.

78 Rockwell Automation Publication 2080-UM005A-EN-E - December 2013

on page 51 for more

on page 108.

Datalog Directory Structure

The DATALOG folder is created under the current project directory in the microSD card. This folder is created by default unless another directory has been specified in the ConfigMeFirst.txt. See

ConfigMeFirst.txt Configuration Settings

on page 76.

Subdirectories are also created following the controller RTC timestamp. This means that if RTC date at the time of function block execution is February 02, 2013, the subfolder 2013 is created under DATALOG. Under the 2013 folder, the subfolder 02 (which stands for the month of February) is created. Under 02, another subfolder 02 is created, corresponding to the current date.

Under the current working folder, the subfolder Grp01 is created. A maximum of 50 Grpxxx folders can be generated on the microSD card per day.

Under the current Grpxxx working folder, the datalog file File01.txt is created. Once this file reaches more than 4 KB, another file, File02.txt, is automatically created to store data. The file size is kept small in order to minimize data loss in case the card is removed or when there is unexpected power off. Each Grpxx folder can accommodate up to 50 files. This means that, for example, when the Grp01 folder already stores 50 files, a new folder Grp02 is automatically created to store the next datalog files for that day. This automatic folder and file generation goes on until the Grpxx folder reaches 50 for that day. When a microSD card is inserted, the DLG function block looks for the last Grpxx folder and filexx.txt file, and proceeds to do the datalogging based on that information.

These datalog files are for February 2, 2014.

Datalog Function Block Execution

• There are three possible states for the Datalog function block: Idle,

Busy and Complete (which includes Complete with Succeed and Complete with Error).

• For one Datalog function block execution, the typical status starts

from Idle, then Busy and finishes with Complete. To trigger another function block execution, the status needs to go back to Idle first.

• Idle status changes to Busy status only when Enable input signal is in

rising edge. Complete status enters Idle status when Enable input signal is Disable status only.

• TSEnable and CfgId input parameters are only sampled at Enable

input parameter's rising edge when a new function block execution starts. During function block execution, the input parameters of TSEnable and CfgId are locked and any changes are ignored.

• When execution completes, the status changes from Busy to

Complete. At this stage, if input Enable is False, status changes to Idle after indicating Complete for exactly one scan time. Otherwise function block status is kept as Complete until input Enable changes to False.

• The datalog file can only be created by the DLG instruction block.

Connected Components Workbench can only upload and delete the datalog file.

• There are separators in between every data variable in the data file

which is defined during configuration in Connected Components Workbench. See Supported Data Types for Datalog and Recipe Function Blocks

page 82.

• Data variable values are sampled when datalogging function block is

in Busy state. However, datalogging file is only created when datalogging function block is in Complete state.

changes from Busy to Complete. At this stage, if input Enable is False, function block status changes to Idle after staying as Complete for exactly one scan time. Otherwise, function block status remains Complete until input Enable changes to False.

• Recipe function block file name supports a maximum of 30 bytes in

length, and only supports upper and lower case letters Aa…Zz, numbers 0…9 and underscore (_).

• The RcpName input parameter does not allow file extension (for

example, .txt) to be added to its value. The recipe data file is written to the microSD card with the .txt extension.

• There are separators in between every data variable in the recipe

data file which is defined during configuration in Connected Components Workbench. Redundant tab, space, carriage return and line feed characters are strictly not allowed. See Supported Data Types for Datalog and Recipe Function Blocks

page 82.

• Double quotes are not allowed within a string in a recipe file.
