About MConfigPro

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

sequence of operation

setpoint s

timers

faults

displays

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

Installing MConfigPro

System Requirements

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

While the MConfigPro software will function on any pc or laptop running Windows, it will notperform transfers using the USB driver unless the operating system supports USB. USBsupported operating systems include Win98SE, NT, and XP.

Serial transfers using standard communication ports (COM1, COM2) should be possible on allWindows platforms.

The MConfigPro software and USB driver provide efficient use of your hard drive, using only 3-5 MB of disk space after installation.

Setpoints

There are 128 configurable setpoints that may be edited. Setpoints further configure variablerange input types such as mpu, analog, or thermocouple by defining a threshold, exception orany other out-of-limit event that may require action. Multiple setpoints are often applied to aprocess and they may be configured as often as needed to meet changing conditions.Common alarm and shutdown setpoints a user might configure include:

High Shutdown

Low Warning

Open Warning

High Warning

Low Shutdown

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 thepumps start and stop functions.

Global Timers

Generally, global timers affect process I/O and the arming of associated events. All eventtypes can be associated with, and locked out by Bx, C, or Sx timers.


29/50

Section 50 00-02-060208-31-06 - 25 -

Field DescriptionDescription There are 13 available global timers.

B1 The first global timer used for delaying an eventcondition 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 eventcondition detection. B2 is also known as a secondaryLockout Timer. This timer runs in parallel with B1.

C The delay allowing a clear reading before beginningtesting for the arming of Class C events. The typical timefor most applications is 2 seconds.

S1 thru S5 Users have up to five (5) options to assignadditional 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 isenabled after B1 expires, and begins timing after theexpiration of any of the pulse transition times configured inthe digital input dialog.

Test Time given to allow for maintenance testing of enddevices 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 delayignition until engine crank rollover can occur.

Fuel On Delay Time delay before the assigned fuelvalve output is turned on. This is typically used to delayfuel until ignition has been turned on.

Ignition Off Delay Time delay before the assignedignition output turns off. This is typically used to burnremaining fuel vapors after the fuel valve is turned off.

States

States 6 thru 8 (A) are designated for engine cranking and therefore perform differently thanother states. When State 8 (Crank Rest) either times out or meets the permissive, it recyclesback 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 loadand unload functions. When State 11 (Wait to Load) times out or meets the permissive, it thencycles to State 12. When State 12 (Run Loaded) times out or meets the permissive it cyclesback 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 inMConfigPro. A PID provides a constant feedback loop, in which the PID can correct for ameasured process variable against a desired setpoint , output the corrective action to theprocess and wait for and recalculate the next measurement. The ultimate goal of the PID is toreduce the error to zero.

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

Field DescriptionDescription 4 entries are provided to setup PIDs. The system generated names

may be changed to a more descriptive name of your choice. The field

length for description is 13 characters.

In Use Active PIDs must be set to In Use in order to show up onsubsequent configuration screens. Once the PID is set to In Use,the entry turns to bolded text.

Flag Increase Flag increase on increasing difference

error.Minimum Output Percentage as minimum output.Maximum Output Percentage as maximum output.

Proportional The output value that is proportional to the change of error.Integral To prevent the PID from oscillating or overshooting the setpoint,

assign a value to reset the system to produce zero error, or nudgethe process variable to the setpoint . This value is typically set tozero.

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

system.Override Type None

Digital Setpoint

Override Signal Options based on the Override Type.Override RampAmount

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

Override Ramp Time Time interval value to wait before making the next adjustmentOverride Max Change A maximum allowed change. This represents the total amount of

change allowed into or out of the ramp amount from the setpoint. Themaximum change value should be large enough to effect change.

Guidelines for Configuring MConfigPro

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

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

Defining the System

System of Protection

System of Operation

System of Interface

Defining the System

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

The following items from the Main Menu List allow you to define the system. Refer to thechapter titled Main Menu List - Screen Definitions for information on field options you will beentering.

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 theproduct.

Maintenance Timers

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

System of Protection

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

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 optionsyou 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, normaloperation of your equipment. The following items from the Main Menu List allow you to definethe system of operation. Refer to the chapter titled Main Menu List - Screen Definitions forinformation on field options you will be entering.

StartupWhat 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 theequipment. The ideal operating condition is Run Loaded.

Miscellaneous

The miscellaneous menu option contains various options to be set that dont directly relate toprocess I/O. They control items such as number of crank attempts and oil pressure source andwater temperature source.

PID

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

System of Interface

This sequence determines the communication port setup for downloading the MConfigProconfiguration files. It also determines how information is displayed on the Centurion. Thefollowing items from the Main Menu List allow you to define the system of interface. Refer tothe chapter titled Main Menu List - Screen Definitions for information on field options you willbe entering.

Comm Port Settings

Determine which type of connection will be used:

USB Connection

Serial Connection (RS-232 or RS-485)

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

Display ScreensThis 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 controllerthrough 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.
