2.0 Overview

The Centurion configurable controller is a control and monitoring system expressly designed to meet the requirements of three specific kinds of applications: Screw and Reciprocating Compressors, and Pumps. To that end, it is able to satisfy the particular needs and inevitable variations that exist in real world applications because the Centurion controller is enormously flexible and configurable within fixed parameters. The Centurion controller is a system designed to monitor, control, protect, and optimize small to medium sized gas operated compressors and pumps in the field by monitoring set points and digital, analog, and thermocouple input points and providing the logic to take corrective and/or proactive steps to maintain proper operation. The Centurion controller also allows for controlled shut down and no-flow monitoring as well as expanded and auto start up, and engine control capabilities, which are so critical to the systems the Centurion controller is designed to protect.

The Centurion controller provides real-time data via communications ports to a connected display and/or supervisory system. This advanced system offers multiple options for remote communications and operation including HMI's, PLC's, PC’s, and SCADA systems. The industry standard Modbus protocol means greater support for a wide variety of communication equipment including radio and satellite communications systems.

The heart of the Centurion system is the Main Input/Output (I/O) Module, known as C3-1, which can be mounted on a standard DIN rail. While it is designed to work with any Modbus (Master) compliant HMI (Human Machine Interface) or with no operator interface at all, it is optimally configured and field-configurable through MConfigPro, powerful software developed to configure the controller. Parameters can be modified through C3-3 Display, F W Murphy’s specially programmed controller display, in the field without special need for laptop or software.

Basic Components and Key Features of the C3TMSeries

The C3 Series consists of a Display Module, a Main I/O Module, and optional Expansion I/O Module. No special cables are required. The Centurion system is designed for use within a weatherproof enclosure only.

The graphic LCD displays are organized around operating status screens and setup screens. The actual number of status screens will be related to the total number of end devices configured for the controller. In either screen set, ten (10) lines are visible at a time; with up and down arrow characters indicating more lines are available on the page. Also, for both screen sets, navigation between screens is accomplished by pressing the left or right arrow keys.

66..11..33 NNuummeerriicc EEnnttrryy

The C3-3 Display uses a different approach to enter values than previous Murphy controllers. Instead of holding in the arrow keys until the desired number is displayed, the Centurion display allows individual editing of each position of the desired number. This is accomplished by entering the Edit Mode and using the UP/DOWN arrow keys (1) to adjust the number above the blinking cursor (2) between 0 and 9. To edit another position, simply use the LEFT/RIGHT (3) arrow keys to move the cursor to that position (4) and repeat the edit process until the desired number is displayed.

In this way, values are “built” rather than “scrolled” through. Some digits may not be allowed to increment if it would result in exceeding range limits. Values which can be positive or negative will have a sign (±) to the left of the number. To change the sign value simply move the cursor to the sign using the LEFT arrow key and “toggle” between + and – using the U and DOWN arrow keys. If the range of the value will exceed range limits the sign may not be allowed to change. In this case, try reducing the numebr by decrementing the left most digit by one or more and attempt to change the sign again.

In some instances, a word rather than a value is represented in the Edit Mode. This works like the sign value as an ON/OFF or YES/NO prompt where the value is “toggled” between choices using the UP/DOWn arrow keys. The value is not active in the controller until the ENTER key has been pressed to send the value to the controller. Pressing the ESC key will discard any changes and keep the original value prior to entering the Edit Mode.

6.2 Operational Screens

In addition to the set up screens reviewed in Section 7.3, the C3-3 Display offers a number of operational displays. On the Operating Status screens, the two bottom lines display the state, hours, mode and active timer status. This information is key to understanding the “status” of the controller.

Mode refers to the Operating Mode of the controller and can be LOCAL or REMOTE. Depending on the configuration active in the controller, the operation may differ depending on what Mode the controller is currently displaying.

NNOOTTEE::

The Mode can be changed by pressing certain keys, if the configuration allows for REMOTE mode. Pressing RESET or RUN/STOP is a Local function and will change the Mode to Local if it is in REMOTE. Pressing Fn before pressing RESET or RUN/STOP is a REMOTE function and will change the Mode to REMOTE if it is in LOCAL.

After turning on the power, the user will view the F W Murphy logo screen for three seconds before the next screen displays, which is a software-configured default operating screen. The MConfigPro software allows users to configure up to five screens with controller I/O groupings. Possible custom screen types that may have been configured as a default operating screen, or which may be also displayed, include:

a) Custom Line by Line allows process data to be displayed in a list format with description and value. b) Custom Gage allows user to display four (4) most important pieces of data on a 2 x 2 table in larger font. c) Custom PID up to 4 PID screens.

For more information on configuring the optional screens through the MConfigPro software, please refer to the Centurion Controller Programming Manual.

66..22..44.. SShhuuttddoowwnn HHiissttoorryy SSccrreeeenn The history of the last twenty shutdowns is displayed on this screen, with the most recent at the top of the list and the oldest at the bottom. Each event is displayed with the shutdown label on one line and the hour meter reading on the following line. Pressing the up/down arrows will scroll up/down one shutdown at a time rather than one line at a time. The “1 / 3” at the right end of the top line means the user is viewing shutdown one of a total of three stored. The newest shutdown will always be number one and it will push the older shutdowns further down the list.

66..22..55 EEvveenntt HHiissttoorryy SSccrreeeenn The user easily can view the events (alarms, etc.) logged before and after a shutdown of interest. There will be a maximum of thirty two events in this history and beyond that a new event will cause the oldest event to be discarded.

66..22..44 AAccttiivvee AAllaarrmmss SSccrreeeenn

All active alarms and warnings will be displayed on this screen. The top line is the screen heading and the next six lines display alarms. If there are more than six active alarms, there will be up/down arrow icons at the bottom of the screen and the user can press the up/down arrow keys to scroll up or down. Unacknowledged alarms will be preceded by a musical note character and acknowledged alarms will have a bar through the staff of the note. Pressing ACK on this screen will acknowledge all active alarms.

This screen shows the alarm annunciation as it will appear on a status screen. The alarm message(s) will overwrite the bottom line of the active screen area and then briefly clear once a second. This will continue until it is acknowledged with the ACK, key unless it is a self-clearing alarm. If there is more than one unacknowledged alarm active, each alarm will be displayed for one second each until acknowledged. The ACK key will acknowledge the alarm currently displayed. Pressing the Fn key followed by the ACK key will switch to the Alarms screen.

6.3 Setup Screens and Menus

66..33..11 PPaasssswwoorrdd SSccrreeeenn Some settings are password protected, including the setup screens. This is the first screen seen when the SETUP/ENTER key is pressed.

The password need only be entered once during any editing session. The password will reset when the editing session is exited, or is timed-out due to keyboard inactivity.

The cursor begins at the last digit on the right. The user can adjust the value of each digit with the up/down arrows while the left/right arrows are used to select the digit to edit.

Passwords are assigned using the MConfigPro software and each digit can range from zero to nine (except the first digit on the left) for a total range of 00000 to 65535 for the complete password.

The user will not be allowed to increment the selected digit if it would result in exceeding range limits.

There are three separate levels of passwords to accommodate several security needs:

• “Standard” password – Allows access to every feature except the Super User menu. Valid Standard passwords can be zero or any number between 100 and 65535. If the Standard password is set to zero, the result is that anyone can have read/write access to setup menus.

• “Super User” password – Adds the Super User menu to the Standard menus. Valid Super User passwords can be in the range of 100 to 65535. The Super User password can not be the same as the Standard password.

• “Download Only” password – This Special 35 Jump Code allows access to a download menu and is set to a fixed value of 35. This allows a configuration to be downloaded in the event that the current passwords are lost or no initial configuration has been downloaded.

If the Standard password is not zero and a password of all zeroes is entered, the user will have “view only” access.

Inactivity Timeout: Setup procedures must be started and completed in a timely manner. Note that after 3 minutes without activity, the keypad returns the default operational screen and a password must be re-entered to return to the setup and edit menus.

66..33..77 GGeenneerraall TTiimmeerr SSeettuupp User may edit all general purpose timers. Generally, global timers affect engine operation. They also help define an event.

aa))

B1: All event types can be associated with, and locked out by, a Bx timer. B1 is the first global timer used for delaying an event condition detection. The timer starts in a running State (10 – 13) depending on which have been marked ‘In Use’. B1 is also known as the “Lockout Timer.”

bb))

B2: The second global timer used for delaying an event condition detection. B2 is also known as a secondary “Lockout Timer.”

cc))

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

dd))

S: Users have up to five (5) options to assign additional special global timers to signals. The Sx timers begin concurrently with the Bx timers.

ee))

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 any of the no flow transition times configured in the digital input dialog expires.

ff))

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.

gg))

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.

hh))

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.

ii))

Fuel On Delay: Time delay before the assigned fuel valve

output is turns on. This is typically used to delay fuel until ignition has been turned on.

66..33..99 SSeett ppooiinnttss SSeettuupp User can edit any of the 128 set points that are configured. Set points further configure analog inputs and thermocouple inputs by defining a threshold, exception or any other out-oflimit event that may require action. Multiple set points are often applied to a process and they may be configured as often as needed to meet changing conditions.

Common alarm and shutdown set points a user might have configured include:

High Shutdown Low warning Open Warning High Warning Low Shutdown

A user might also have configured other set point settings which are not used to indicate alarm or shutdown. For example, a set point provides a less flexible, but simpler alternative to controlling the pump’s start and stop functions.

To edit a configured set point:

aa))

Assign numeric threshold that if crossed, triggers the set point.

bb))

Adjust the sign of the threshold value as plus (+) or minus (-) by moving the cursor to the sign symbol position and use the up and down keys to toggle the sign.

For more on Set Points, please refer to the Centurion Configurable Controller Programming Manual.

66..33..1100 CCoonnttrrooll OOuuttppuutt SSeettuupp

The Centurion controller allows users to define up to eight (8) outputs to augment control not otherwise defined.

The Centurion controller can be configured through MConfigPro software to define an analog output, a digital output, a single pulsed digital output, or two pulsed digital outputs.

Note that Control Outputs 1 through 4, are directly related to Proportional Integral Derivative (PID) calculation loops and are further defined in the PID dialog screens described in Section

6.3.11. For example, PID 1 is assigned its control from Control Output 1, PID 2 from Control Output 2, and so on.

If the configured output is a pulsed cycle, the user may edit those behaviors by following the available steps:

aa))

Assign value to Increase Max On Time. (Set limit of maxi-

mum on-time for Increase pulses.)

bb))

Assign value to Increase Off Time. (Set fixed off-time for

Increase pulses.)

cc))

Assign value to Increase Changeover On Time. (Set fixed

on-time for single pulse on direction change for Increase).

dd))

Assign value to Increase Changeover Off Time. (Set fixed

off-time for single pulse on direction change for Increase).

ee))

Assign value to Decrease Max On Time. (Set limit of maxi-

mum on-time for Decrease pulses.)

ff))

Assign value to Decrease Off Time. (Set fixed off-time for

Decrease pulses.)

gg))

Assign value to Decrease Changeover On Time. (Set fixed on-

time for single pulse on direction change for Decrease).

For more on Control Output, please refer to the Centurion Configurable Controller Programming Manual.

66..33..1111 PPIIDD SSeettuupp Users may view and edit up to four (4) MConfigPro software configured Proportional Integral Derivative (PID) calculation loops. A PID provides a constant feed back loop, in which the PID can correct for a measured process variable against a desired set point, 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 a control output. Recall that PID 1 is assigned its control from control output 1, PID 2 from control output 2, and so on.

To View and Edit PID Settings:

11))

Over Ride Ramp Time: Assign a time interval value to wait

before making the next adjustment.

22))

Over Rid Ramp Amount: Determine the increments in a given direction (positive or negative) that the set point 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 set point.

33))

Ramp Time: Assign a time interval for the PID to calculate error.

44))

Over Ride Max Change: Assign a maximum allowed change. This represents the total amount of change allowed into or out of the ramp amount from the set point. The maximum change value should be large enough to effect change.

55))

Set Point: Assign the desired goal—the target feedback base value.

66))

DeadBand: Assign a value around the set point during which the PID will not calculate error.

77))

Minimum Output: Assign a percentage as minimum output.

88))

Maximum Output: Assign a percentage as maximum output.

99))

Proportional: Adjust the output by a value that is proportional to the change of error.

1100))

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

1111))

Derivative: Assign a value to the rate of change of error. This value is typically set to zero.

1122))

Max Override Change: Assign a percentage rate of change over which would cause harm to the system.

7.0 Communications

7.1 Communication Ports

Port 1 (SERIAL)

Port 1 is intended as the primary port for the local device, the C3-3 Display, and should be utilized for C3-3 Display in order for the boot loader mode to properly execute in pass-thru mode. Interface: Refer to the Sequence of Operations to determine how the communication port has been configured. Protocol: Modbus (Slave) Connection: There are three (3) screw terminal connectors for RS485. These are identified as A, B, and SHD. There are three (3) screw terminal connectors for RS232. These are identified as RX, TX, and DTR. SHD is common for both ports.

Port 2 (SERIAL)

Interface: Refer to the Sequence of Operations to determine how the communication port has been configured. INSERT DIAGRAM? RICK NOTES ON PREVIOUS MARKUP Protocol: Modbus (Slave), Proprietary (Binary) Connection: There are three (3) screw terminal connectors for RS485. These are identified as A, B, and SHD. There are three (3) screw terminal connectors for RS232. These are identified as RX, TX, and DTR. SHD is common for both ports. Modbus Slave Address Configuration: The operator may assign a unique Modbus address to each controller (slave) unit that may be in the system. This allows the master controller to differentiate between the modules. For example, to name the controller address 21, place the shunts on LK1, LK4, and LK16 (1 + 4 +16 = 21). Typically, this configuration is set to (1) by the factory.

7.2 Downloading Configurations and Firmware Updates

Users will need to download configurations from the controller, as well as be able to receive occasional firmware version updates from Murphy.

77..22..11 BBoooott LLooaaddeerr It is necessary for the Centurion controller to enter boot loader mode in order to receive downloads for a firmware update, and if configuration between the devices needs to be synchronized. During boot loader mode the Centurion is able to transmit and receive configuration updates to and from the MConfigPro software and transmit configuration updates to C3-3 Display through Pass Through. Communications will operate according to default state parameters for configuration transfers. During boot loader mode, the transfer rate is 9600, N, 8, 1 and assumes a serial communication port setting of RS485 or a USB connection. Due to the Modbus strings of code, the controller recognizes whether the bootloader is for a configuration, or firmware update. In order for the Centurion configurable controller to enter boot loader mode, the jumpers are removed during power up (power cycled). The C3-3 Display and third party HMI devices will not receive a response to polls on Port 1 while the boot loader is active. Power on the Centurion must be cycled with the jumper installed to resume normal operation, or run mode.

77..22..22 DDoowwnnllo

oaaddiinngg CCoonnffiigguurraattiioonnss VViiaa CC33--33 DDiissppllaayy

All configuration downloads will use a baud rate of 9600. The Com 1 selection will use the hardware setup of the current configuration. The Com 2 selection is a fixed hardware setup for RS485. Selecting USB for configuration download connects the USB adapter to Com 2 internally.

All normal communication with the controller is stopped while in download mode.

The display will indicate the transfer is complete by displaying 100%.

SSppeecciiaall 3355 JJuummpp CCooddee In the case that no configuration has been downloaded, or a password has been lost, C3-3 Display allows a “Download Only” password that will allow access to the download menu.

The password is set to a fixed value of 35.

Firmware updates for the C3-3 Display require a USB connection. While boot loader mode for the display is not required for configuration downloads, it is required for firmware updates.

The bootloader can be entered by menu selection if the USB cable is currently connected, otherwise the C3-3 Display will reset and restart the current application firmware. Optionally, the bootloader can be entered by connecting the USB cable and cycling power. (This method will leave the display blank while in the bootloader.)

Upon entry to the bootloader, all communication to the controller will stop. There is a red status LED below the USB connector that will blink three times and then remain on while the bootloader is active.

While a file is being transferred, the Com 2 transmit LED will appear to be lit continuously. A successful download should complete in approximately five minutes.

77..22..66 EErrrroorr MMeessssaaggeess There may be occasion when an invalid configuration error might display because the configuration between the Centurion controller and its devices are out of synch--that is to say the checksums do not match. In fact, the invalid configuration screen will appear briefly after downloading configurations until comparisons are made.

Field testers may decide to ignore the message, if the user knows that the changes are not critical. The user may direct the error message to be ignored through a setting at the super user (password protected) menu. At CONFIG FAIL DISABLE, the user would select Yes to ignore the data mismatch.

The setting is temporary as once power is cycled on the Display, the error message will continue until comparisons between the devices yield no configuration mismatch.

However, if the user knows of changes that might have resulted from changes made fine tuning in the field and wants to synchronize the data, he may choose to do so and there are a couple of options available.

● A super user could choose to also download the configuration from the super user menu on C3-3

Display.

● A user who without access to the super user menu could activate the download through the Special

Jump Code 35.

This screen indicates that the controller is not responding to poll requests. There are only two ways to exit this screen, either by normal responses resuming or if the SETUP/ENTER key is pressed.

This screen will be displayed when a configuration fault is detected. Possible sources of the fault include a corrupt or missing configuration in the display, a corrupt or missing configuration in the controller or a mismatch of configurations in the display and controller.

Note that this error message does not always indicate a problem, but may only signify that initial comparisons between devices do not match. This screen will appear briefly after configuration downloads and may appear briefly after initial communication is established until comparisons are complete.

The fault can be resolved by downloading the proper configuration to one or both devices.

7.3 Modbus Protocol

The Centurion configurable controller was programmed with the Modbus protocol which is a system is based on a “master” and “slave” relationship. With Modbus protocol, the master and slave are able to continue to communicate with each other through defined messages over a variety of network types. The master initiates the queries or commands, and the slave responds to the query with a message or takes action based on the query. In this case, the master is either MConfig (or another Modbus client software), or C3-3 Display, but never both simultaneously as there can only ever be a single Modbus master.

The Centurion system communicates through Modbus using Remote Terminal Unit (RTU) transmission mode to maximize data processing.

As with all numeric data defined within Modbus, the programming is limited to accepting integers (whole numbers only, no decimals). This is important whenever a decimal point is defined for analog inputs.

For example, for the controller to properly read “100.0” with an implied decimal point of 1, the user would need to enter “1000” and 1000 would be stored in the appropriate Modbus register. From the C3-3 Display, the value will be represented with a decimal in the fixed position.

For additional information, please refer to the Centurion Configurable Controller Programming Manual.

7.4 Features of Transferring Data in Modbus

Note that text visible in the MConfigPro software and on the C3-3 Display is not stored in the Centurion controller. Except for the version description in the Version and Security dialog for each configuration file, descriptions assigned in the configuration are not stored in the Centurion controller. Descriptions for various I/O and processes are downloaded to the C3-3 Display and reside as a configuration in that device only. Configurations of the C3-3 are one way only.

Parameter changes made in the C3-3 Display are actually communicated to the Centurion controller where the logic resides. No changes made through the C3-3 Display affect the C3-3 Display configuration as the display merely reads from, and writes to the Centurion main I/O module. As such, the display can write numeric parameters to the controller.

7.5 Modbus Register Address Listings

For a complete MODBUS address map, please refer to The Centurion MODBUS reference document.
