About MConfigPro

MConfigPro is a pc-based configuration software for the Centurion controller. The easy-to-use interface enables you to modify features of the Centurion such as:

• timers

• faults

• displays

File transfer utilities for configuration and firmware upgrades are provided so that once the configuration is set, it may be downloaded from your pc to the Centurion via a serial or USB connection.

Installing MConfigPro

System Requirements

A serial port (RS485/232) or USB 1.1 connection is required for transferring the configuration from MConfigPro to the Centurion.

While the MConfigPro software will function on any pc or laptop running Windows, it will not perform transfers using the USB driver unless the operating system supports USB. USB supported operating systems include Win98SE, NT, and XP.

Serial transfers using standard communication ports (COM1, COM2) should be possible on all

Windows platforms.

The MConfigPro software and USB driver provide efficient use of your hard drive, using only 3-

5 MB of disk space after installation.

• Debounce – provides a timed condition for processing the digital input. The input must be active for the duration of the delay before it will be recognized as active by the controller application.

Once recognized, the digital input must be inactive for the duration of the delay before it will be recognized as inactive by the controller application.

This type of signal condition is useful in process conditions such as unstable tank levels.

• Pulse – provides a timed transition condition for processing the digital input. The input will reset the timer each time the input changes condition. If the input does not change conditions in the delay period specified, the controller will signal the event system.

Pulse Delay Type also provides tracking counters for number of transitions and last and current pulse duration. This information is available on the Centurion display.

Setpoints

There are 128 configurable setpoints that may be edited. Setpoints further configure variable range input types such as mpu, analog, or thermocouple by defining a threshold, exception or any other out-of-limit event that may require action. Multiple setpoints are often applied to a process and they may be configured as often as needed to meet changing conditions.

Common alarm and shutdown setpoints a user might configure include:

Setpoints may also be configured for other processes besides alarm and shutdown settings.

For example, a setpoint provides a less flexible, but simpler alternative to controlling the pump’s start and stop functions.

Field

Description

Value

Description

There are 13 available global timers.

• B1 – The first global timer used for delaying an event condition detection. The timer starts in a running State (10-

13) depending on which ones have been marked “In Use”.

B1 is also known as the “Lockout timer.”

• B2 – The second global timer used for delaying an event condition detection. B2 is also known as a secondary

“Lockout Timer.” This timer runs in parallel with B1.

• C – The delay allowing a clear reading before beginning testing for the arming of Class C events. The typical time for most applications is 2 seconds.

• S1 thru S5 – Users have up to five (5) options to assign additional special global timers to signals. The Sx timers begin concurrently with the Bx timers.

• NF – No Flow: The global delay used for delaying the triggering of a no flow event. This global no flow timer is enabled after B1 expires, and begins timing after the expiration of any of the pulse transition times configured in the digital input dialog.

• Test – Time given to allow for maintenance testing of end devices without triggering a fault or shutdown condition.

The timer initiates when switched to test mode.

• Ignition on Delay – Time delay before the assigned ignition output turns on. This is typically used to delay ignition until engine crank rollover can occur.

• Fuel On Delay – Time delay before the assigned fuel valve output is turned on. This is typically used to delay fuel until ignition has been turned on.

• Ignition Off Delay – Time delay before the assigned ignition output turns off. This is typically used to burn remaining fuel vapors after the fuel valve is turned off.

Section 50 00-02-0602

States

States 6 thru 8 (A) are designated for engine cranking and therefore perform differently than other states. When State 8 (Crank Rest) either times out or meets the permissive, it recycles back to State 6 (Crank Stop). This cycle will continue until a permissive is met in State 7

(Crank).

States 10 thru 13 (B) are the Running states. States 11 and 12 work in tandem to perform load and unload functions. When State 11 (Wait to Load) times out or meets the permissive, it then cycles to State 12. When State 12 (Run Loaded) times out or meets the permissive it cycles back to State 11. This cycle will continue until an event or Stop occurs.

To prevent the cycle, set the time in State 12 to 65535 and do not use a permissive.

PID

Up to four (4) Proportional Integral Derivative (PID) calculation loops may be configured in

MConfigPro. A PID provides a constant feedback loop, in which the PID can correct for a measured process variable against a desired setpoint , output the corrective action to the process and wait for and recalculate the next measurement. The ultimate goal of the PID is to reduce the error to zero.

During the time a PID is enabled, the PID always overrides control output settings found in the states dialog. Recall that PID 1 assumes control of control output 1, PID 2 assumes control of control output 2, and so on.

Options based on the feedback type.

Feedback Base

Setpoint

The desired goal—the target feedback base value.

RampTime (250ms)

Time interval for the PID to calculate error.

Deadband

Value around the setpoint during which the PID will not calculate error.

Minimum Output

Maximum Output

Proportional

Integral

Percentage as minimum output.

Percentage as maximum output.

The output value that is proportional to the change of error.

To prevent the PID from oscillating or overshooting the setpoint, assign a value to “reset” the system to produce zero error, or nudge the process variable to the setpoint . This value is typically set to zero.

Derivative

Value to rate of change of error. This value is typically set to zero.

MaxRate of Change

Percentage rate of change over which would cause harm to the

• Setpoint

Override Signal

Override Ramp

Amount

Options based on the Override Type.

Determine the increments in a given direction (positive or negative) that the setpoint should be altered to regain balanced processes. In the example of the discharge and suction pressure application, this value would indicate how much the PID should resist its goal in reaching the setpoint.

Override Ramp Time

Time interval value to wait before making the next adjustment

Override Max Change A maximum allowed change. This represents the total amount of change allowed into or out of the ramp amount from the setpoint. The maximum change value should be large enough to effect change.

Guidelines for Configuring MConfigPro

This section provides guidelines for setting up common configuration items in MConfigPro such as inputs, outputs, setpoints, timers, alarms, and events, etc. for pumps, reciprocating compressors, and screw compressors. For detailed screen/field information, refer to the chapter titled “Main Menu List - Screen Definitions”.

There is a logical sequence to follow when configuring the Centurion. These sequences will be explained in four separate topics. They are:

• Defining the System

Defining the System

The first step in defining the system is to gather information for setting up your analog and/or digital devices and control outputs. For your convenience, you may want to make a checklist of this information for entering into MConfigPro. Once this information has been entered, it will be available for subsequent configuration options.

The following items from the Main Menu List allow you to define the system. Refer to the chapter titled “Main Menu List - Screen Definitions” for information on field options you will be entering.

I/O Scheme

Define the I/O scheme of devices you have:

• Digital Input/Output devices

• Analog Input/Output devices

Control Output

Define Control Outputs, based on control type (analog, digital, 1 or 2 pulsed digital)

Global Timers

What are the manufacturers suggested specifications for protection to create the necessary setpoints? This information can usually be found in the equipment manual that came with the product.

Maintenance Timers

What are the recommended intervals for maintenance? This information can usually be found in the equipment manual that came with the product.

Section 50 00-02-0602

System of Protection

This portion of the configuration allows you to setup events to define when a system will indicate an alarm, a message, or will be shutdown. It also allows for defining how an alarm is cleared.

Shutdowns may be defined by the following types:

• Stop – a controlled stop under normal conditions

• Fault SD – abnormal conditions with minimal consequences (not catastrophic)

• ESD – immediate emergency shutdown

The following items from the Main Menu List allow you to define the system of protection.

Refer to the chapter titled “Main Menu List - Screen Definitions” for information on field options you will be entering.

Events

What steps need to be taken to shutdown equipment on Stop, Fault SD, or ESD conditions?

What types of alarms or messages need to be defined and how will they be acknowledged?

System of Operation

The sequences to be defined for system of operation determine the day-to-day, normal operation of your equipment. The following items from the Main Menu List allow you to define the system of operation. Refer to the chapter titled “Main Menu List - Screen Definitions” for information on field options you will be entering.

Startup

What are the procedures for initiating a start?

RPM Control

Consideration point: If control outputs exist, do they need RPM control?

States

States reflects all steps from evaluating conditions, to controlling start, stop, and running the equipment. The ideal operating condition is Run Loaded.

Miscellaneous

The miscellaneous menu option contains various options to be set that don’t directly relate to process I/O. They control items such as number of crank attempts and oil pressure source and water temperature source.

PID

PID runs as a parallel process to System of Operation. Determine at what point or state type it is enabled.

Section 50 00-02-0602

System of Interface

This sequence determines the communication port setup for downloading the MConfigPro configuration files. It also determines how information is displayed on the Centurion. The following items from the Main Menu List allow you to define the system of interface. Refer to the chapter titled “Main Menu List - Screen Definitions” for information on field options you will be entering.

Comm Port Settings

Determine which type of connection will be used:

• Serial Connection (RS-232 or RS-485)

Specify behavior of communication ports. Specify how to represent various information coming from the comm ports.

Display Screens

This step is only necessary if the system of interface is the Centurion display.

Configuration Download Instructions

Once your configuration files are setup, you may download them to the Centurion controller through either a USB port, or serial port (Com1 or Com2).

Comm. Port Settings

Before you can download files to the Centurion controller, the communication port settings must be established for serial ports Com1 or Com2.
