Press Key for Dnload ***System is not Configured*** Press Any Key to Enter Download Mode Pressing any key on the OIT causes the OIT to enter download/upload mode.
Getting Started 16 2. Type the setup password and then press the following key on the OIT. If there is no setup password, just press the following key. NOTE: You must start entering your password within 5 seconds, or the OIT exits setup mode.
Getting Started 17 Transfer the OITware-200 Project When you receive your OIT from the factory, it does not contain any information on how it is to operate. Therefore, the first time you download a project to the OIT you must also download the Operational Software. Downloading the Operational Software takes approximately three minutes to complete. Sending only the project file reduces the download time to approximately 30 seconds. To download an OITware-200 project to the OIT: 1.
Getting Started 18 Verifying the OIT is Operational Now that you have successfully downloaded an OITware-200 project to the OIT, you can connect the OIT to a PLC and verify that the OIT is operational. To verify the OIT is operational: 1. Connect the OIT to a PLC. Please read your OIT Installation Manual before connecting the OIT to a PLC. 2. Apply power to the OIT and PLC.
Getting Started 19 4. The OIT attempts to write 0 to the status coils (if feature not disabled in OITware-200). If not successful, the following message is displayed: OIT Model OIT3100 and OIT4100 Series All other models Message Cannot write to the Status Coils! Error: Setting up StatusCoils On Startup 5. The OIT attempts to write 1 to the Reset status coil (if status coils are enabled).
Operational Overview 20 CHAPTER 2 Operational Overview The OIT Family Operator Interface Terminals communicate with PLCs by using point-to-point serial communications to read from and write to the internal registers and coils of the PLC. Six sets of registers and coils located within the PLC’s internal memory are designated for special purposes: the Message Request Register, Current Message Register, Key coils, Status coils, Status LED coils, and Function Key LED coils.
Operational Overview 21 Message Request Sequence PLC Clears "0" Message Received Coil PLC Writes Message # Message Request Register OIT Reads Message # OIT PLC Program PLC Reads Coil to Check Message Displayed Message Displays Message Received Coil OIT Sets "1" To display a screen, the following activities occur within the PLC and the OIT: • The PLC checks the message received status coil to ensure that the previous screen has already been processed by the OIT (optional).
Operational Overview 22 Enhanced MRR Features The following enhanced MRR features are only available on the OIT3100 and OIT4100 Series. Bit vs Value The default MRR is a “value” MRR. Which means that the PLC calls screens by placing decimal or BCD numbers into the MRR. If you need the PLC to call a screen by setting a bit instead of writing a number, you need to use a “bit position” MRR.
Operational Overview 23 is shipped to its final destination, the OIT operator places the OIT into the setup mode and selects which language is to be displayed. To enable the multi-language feature: 1. In OITware, select the Configuration menu, then select Message Control Settings. 2. Check Enable Multiple-Language Support checkbox under Language Settings. 3. Use the pull-down box to select how many languages you want supported: 2, 5, or 10. 4.
Operational Overview 24 Key Coils There are three types of coils in the PLC that are used to pass keypress data from the OIT to the PLC: Control Key coils, Function Key coils, and Screen Dependent Function Key coils (SDF keys are only available on the OIT3100 Series, OIT4100 Series and OIT5400B). Control Key Coils Each key on the OIT (except function keys) can be configured to perform its normal OIT action and/or set a PLC coil.
Operational Overview 25 Function Key Coil Example If you want a motor to run whenever the F1 function key is being pressed by the operator, the relay ladder logic could be the following: C389 Y33 In this case, internal control relay C389 has been configured as the Function Key coil for the F1 function key. If the F1 function key has been configured as momentary, then C389 will be activated as long as the F1 function key is being pressed by the operator.

Operational Overview 27 Reset The Reset status coil is set by the OIT each time it powers up or performs a reinitialization due to exiting the OIT’s local setup menu. This can be used by the PLC to indicate that the OIT has performed a reset. The PLC can clear the coil and decide what to do with the information.
Operational Overview 28 more information on the CMR, refer to the Current Message Register section in this chapter. For more information on alarms, refer to the Alarm Screens section in CHAPTER 3: Stored Screens. Clear Alarm Stack The Clear Alarm Stack status coil is similar to the Clear Alarm status coil except that this coil allows the PLC to clear the entire stack of alarms, including the currently displayed one.
Operational Overview 29 Function Key LED Coils The Function Key LEDs (OIT3250, OIT4450, and OIT5400 only) can either be controlled by the OIT or by a block of discrete coils in the PLC called the Function Key LED coils. When controlled by the PLC: • if the corresponding coil is set, the LED is on • if the corresponding coil is clear, the LED is off. For more information on LEDs, refer to CHAPTER 8: Using the LEDs.
Operational Overview 30 System Speed The OIT hardware and software were designed in such a way that system performance is only limited by the communications speed of the PLC, baud rate of the PLC, and the overhead associated with the PLC protocol driver (the number of characters over and above the actual data used for checksums, data formatting, etc.).
Stored Screens 31 CHAPTER 3 Stored Screens Each OIT Family Operator Interface Terminal is capable of storing up to 500 user-defined screens (250 on the OIT5400). There are five different types of stored screens; each providing a unique function. Screen Type Screen Function Convey information to the OIT operator and allow the OIT operator to change data in the PLC. Allow the OIT operator to setup and start a batch process. Notify the OIT operator of alarm conditions using a message and an audible alert.
Stored Screens 32 Message Screens Message screens convey information to the OIT operator and through the use of PLC Register Monitors allow the OIT operator to change data in the PLC. 1 2 3 4 5 6 7 8 MESSAGE ALARM F1 F5 F9 F2 F6 F10 F3 F7 F11 F4 F8 F12 RUN PRINT LAST MESSAGE PRINT SCREEN 1 2 3 4 ALARM ACK 5 6 PAGE UP SETUP 7 8 9 PAGE DOWN HELP NEXT MESSAGE 0 TOGGLE . CLEAR DELETE E N T E R To create a message screen: 1.
Stored Screens 33 Recipe Screens Recipe screens are screens that, when displayed on the OIT, allow the operator to download or upload preset values into PLC registers. These preset values are configured when programming the OIT and can also be modified (OIT3100/4100 Series only) at any time by the OIT operator. Recipe screens allow the OIT operator to configure and start a batch process. Each recipe screen can include up to 20 ‘preset’ values.
Stored Screens 34 To upload a recipe using the OIT keypad: 1. Display the Recipe Screen using a pre-programmed key or from a screen request by the PLC. 2. The recipe ‘initiator’ is only used for download purposes. Therefore, you must configure a screen-dependent function key to upload the recipe. 3. To upload using a screen-dependent function key, simply press the function key when the recipe is displayed. It is not necessary to change the recipe initiator.

Stored Screens 40 Screen Features Blinking Characters Each character in a message, recipe, alarm, menu, or help screen (including text, special characters, and PLC Register Monitors) can be configured to blink. Those characters with the blink attribute enabled, will blink once per second for as long as the screen is displayed. To configure a character to blink: 1. In the Screen Editor, use the mouse to select the characters that you want to blink.
Stored Screens 41 Screen Chain Often, an event occurs which requires a message or menu be sent to the OIT operator that is longer than the space provided on one screen of the OIT. To compensate for the limited size of the OIT’s display, message or menu screens can be chained together so that they can be viewed in succession. When one of the chained screens is currently displayed, other screens that are chained to it can be displayed by using the PAGE UP and PAGE DOWN keys.
Stored Screens 42 Output to Printer (OIT3250, OIT4450, OIT5400 only) When message and alarm screens are displayed on the OIT they can also be output to a serial printer. For more information on using a serial printer, refer to CHAPTER 9: Using a Serial Printer. To configure a screen to print: 1. In the Destination group box, select the Display & Printer option button. Horizontal Scrolling Each message, recipe, alarm, or menu screen can have a single line of up to 128 characters that scrolls horizontally.
Stored Screens 43 Beep on Display Each message, recipe, or menu screen can be configured to beep for two seconds whenever it is initially displayed. This feature can be used as an attention-getting device. To configure a screen to beep on display: 1. In the Special Effects group box, select the Beep on Display check box. Startup Screen One message, recipe, or menu screen can be designated as the startup screen. The startup screen automatically appears whenever the OIT is powered up.
PLC Register Monitors 44 CHAPTER 4 PLC Register Monitors The PLC’s registers and coils can be monitored, displayed, and updated by the OIT. This is done by configuring the OIT screens to display PLC registers and/or coils as embedded data fields (PLC Register Monitors). When the OIT displays a screen that contains a PLC Register Monitor, the OIT reads the specified PLC register address and then displays the data.

PLC Register Monitors 51 ASCII String - PLC Coil This format is used to represent a single coil in the PLC as a binary value with user-definable strings that indicate whether the coil is on or off. Two ASCII strings can be created to represent the PLC coil. For example, RUNNING to represent the ‘on’ state and STOPPED to represent the ‘off’ state. In OITware, enter the strings to be displayed using the ASCII Table Editor. Up to 30 strings may be entered, each up to 16 characters in length.
PLC Register Monitors To configure the 30 ASCII strings: 1. Refer to the ASCII String - PLC Coil section, above. 1010-0099, Rev.
PLC Register Monitors 53 Bar Graph (OIT5400 only) This format is used to represent a signed 16-bit PLC register as a bar graph. Each bar graph can be configured to display horizontally or vertically. The width and height of the bar graph can be defined, and an optional percentage sign can be displayed in the middle of the bar graph.
PLC Register Monitors 54 Floating Point (OIT3100 and OIT4100 Series Only) This format is used to represent a 32-bit register in the PLC as a Floating Point value. The Floating Point format is based on the IEEE 754 Basic Single Precision Floating Point specification: Number of Bits [bit location] sign exponent mantissa 1 [31] 8 [30-23] 23 [22-0] IEEE 754 Single Precision Due to limitations in the OIT, the implementation of floating point in the OIT is a subset of the IEEE 754 specification.
PLC Register Monitors 55 PLC Register contains: +214,100.45 Decimal Location: 5 ( 21,474.83647 to + 21,474.83647) OIT Displays: ######## If a value is within the specified range, but has a greater precision, then the OIT will truncate the number to the precision of the specified range. See Example 2. Example 2, Out Of Range Precision PLC Register contains: +350.128 (3 decimal places) Decimal Location: 2 (-21,474.836.47 to + 21,474.836.47) OIT Displays: +350.12 (displayed to 2 decimal places).
PLC Register Monitors 56 Decimal Location (OIT3200, OIT3250, OIT3600, OIT4400, OIT4450, OIT5400) This attribute allows you to configure the location of the decimal point in the PLC Register Monitor. The decimal point is placed the specified number of characters from the right (for example: 0 = 12345, 1=1234.5, 2=123.45, etc.).
PLC Register Monitors 57 The linear scaling conversion is accomplished using the simple equation Y=MX+B, where “X” is the raw data read from the PLC, “Y” is the data presented to the OIT operator after the conversion, “M” is used to convert the scale of one unit of measure to another unit of measure, and “B” is the offset variable used for alignment.
PLC Register Monitors 58 To configure linear scaling in a PLC register monitor: 1. In the Register Monitor Editor dialog box, in the Special Effects group box, select the Linear Scaling check box. The Linear Scaling Parameters group box activates.
PLC Register Monitors 59 2. In the Linear Scaling Parameters group box, enter the M1, M2, and B values for your conversion formula or choose the Preset Lists button to select a preset formula from the Linear Scaling Presets List. 3. If this is a read/write register monitor, you can enter low and high limits to stop the OIT operator from entering invalid values.
PLC Register Monitors 60 Leading Zeros This attribute adds leading zeros to the PLC Register Monitor when the Decimal, 4-Digit BCD, or 8-Digit BCD format is used and the data read from the PLC register is shorter than the number specified in the Number of Digits attribute (for example: 0024 would display instead of 24 in 4-Digit BCD format). To enable Leading Zeros in a PLC Register Monitor: 1. In the Register Monitor Editor dialog box, in the Special Effects group box, select the Leading Zeros check box.
PLC Register Monitors 61 Left/Right Justification This attribute displays the contents of the PLC Register Monitor with either left or right justification.

If creating a value MRR, in the Options group box, specify the data format for this MRR. 9.
Displaying Stored Screens 69 Function Keys Every global and screen-dependent function key on the OIT can be programmed to display a stored screen. Whenever the function key is pressed, the corresponding screen is immediately displayed, unless an alarm is active or a security password is being used. For more information on configuring function keys, refer to CHAPTER 6: Key Types. NOTE: When a function key displays an alarm or help screen, the screen is treated like a simple message screen.
Displaying Stored Screens 70 Standard Mode In Standard mode, screens requested by the PLC or OIT enter the stack only after being displayed. When an alarm screen is displayed, all non-alarm screen requests are ignored; they are not displayed or stored in the stack. When the stack contains 10 screens, adding another screen causes the oldest screen to fall out of the stack. When the OIT operator presses the LAST MSG key, the most recent screen in the stack is redisplayed.

Troubleshooting 121 APPENDIX C Troubleshooting Display Brightness and Viewing Angle Can the VFD Brightness be Changed? Yes. In OITware-200 press SHIFT+F4 to open the OIT General Settings dialog box. In the Brightness group box, select the 100%, 75%, 60%, or 30% option button. Can the LCD Viewing Angle be Changed? Yes; except on the OIT3600. To change the LCD viewing angle on the OIT5400, refer to the Installation Manual that came with the OIT.
Troubleshooting 122 When the PLC Requests the Same Screen Twice the Screen is Not Displayed Possible Cause: • If the MRR already contained the screen number that the PLC requested, the OIT would not recognize the screen request. Possible Solution: • Modify the PLC program so that when the MRR already contains the screen number that the PLC is requesting, the PLC writes a zero to the MRR before writing the screen number.
Troubleshooting 123 Possible Solutions: • Verify that your PLC’s mode switch (if applicable) is in the correct position. The switch may need to be in a mode other than run mode; such as terminal mode or xxxxxx mode. Refer to your controller operations manual or the applicable Controller Information Sheet from Maple Systems. • Verify that the PLC password in the OIT matches the password in your PLC. In OITware-200 press F4 to open the OIT - Controller Settings dialog box.
Troubleshooting 124 Alarms How Many Alarms are Supported? Each OIT can store and display up to 500 screens (250 on the OIT5400). Of these 500 screens, any or all can be alarms. How are Alarms Displayed? The PLC requests an alarm screen by placing the number that corresponds to that screen in the Message Request Register (MRR). When the OIT reads the number in the MRR, the OIT displays the corresponding alarm screen, sounds the audible alert, and blinks the alarm LED.
