Page 7: Getting Started
1.0 Getting Started 1.1 What is the MMI-2XX Series? MMI Units are operator interfaces for PLCs. They allow the MMI-2XX Series operator to interact with the machine by displaying messages that are preloaded into them with a Personal Computer and/or turning on LED's. -
Page 8: The Mmi Series And Its Environment
1.1.1 The MMI Series and Its Environment Where The MMI Series is designed for use in a factory environment. Used They are designed to operate under the same temperature conditions as PLC's used in an industrial environment. They may not be suitable for use in certain outdoor applications. Please consult the factory for advised usage in outdoor applications. -
Page 9: Installation Instructions
2.0 Installation Instructions 2.1 Mounting Instructions 2.1.1 Location Considerations. Care should be taken when locating equipment behind the MMI to ensure that AC power wiring, PLC output modules, contactors, starters, relays, and any other source of electrical interference are located away from the back of the unit. -

Mounting the panel cut out. Insert the clamps into the case. Pull back Put the MMI through on the clips until they seat into the retaining slots. Tighten clamping screws to 3 in.lb. of torque in an even pattern until the MMI is secured in the panel. -
Page 11: Power Connections
2.2 Power Connections Make sure that all local and national electrical standards are met when installing the MMI. Contact your local authorities to determine which codes apply. 2.2.1 Power Requirements Power The MMI can be powered by AC or DC power, depending on the part number ordered. - Page 12 Caution Do not power the MMI and inductive DC loads, or input Supply Voltage circuitry to the PLC, with the same power supply. Condition The 24 VDC output from some PLC's may not have enough current to power the DC powered MMI. Caution Power supplies with large capacitive outputs may cause Power Cycling...

Page 13: Grounding Requirements
2.2.2 Grounding Requirements Earth ground must be used. DC ground (Terminal 4) is not directly coupled to Earth ground internally. It is preferable not to ground DC negative return to earth ground, terminal 5, as poor site earths can introduce noise into a system, but if necessary an earth connection should be made, from the power supply return point to the central star earth point. -
Page 14: Communications Connections
This section presents recommended installation practices and procedures. Since no two applications are identical, these recommendations should be consid- ered as guidelines. Hardware Considerations The system designer should be aware that control devices in WARNING! Programmable Controller systems can fail and thereby create an unsafe condition. -

Page 19: Mmi Operations
3.0 MMI Operations Once the MMI is programmed and connected to the PLC, normal operation begins. The MMI establishes communications with the PLC. It then requests the number in the Message Triggering Register (MTR), if used, and displays the corresponding message. -

Display Queue When 34 is done, message 15 will be displayed. Display Queue When 15 is done, message 211 will be displayed. Display Queue EMPTY Message 211 will continue to be displayed until a new message number is put in the MTR or a function key is pressed. -
Page 21: Entering Numerical Values
When a function key is pressed, one of the following conditions will apply. 3.2.1 The Function key may have message text assigned to it, request the operator to edit a value or chain to another message. 1. The Function key message will interrupt the active display. Note: Function keys with message text assigned to them clear the message Queue and interrupt minimum display times, chained and scrolling messages. - Page 22 MMI-220, 240 The MMI-220 and 240 may have data or bit status embedded in a message for the purpose of editing. Such data is usually machine status, setpoints or other setup parameters that may need to be changed from time to time. When a Special or Function key message with an embedded register Action Field is displayed, the value will flash, prompting the operator to input data.

Page 23: Using The Prev And Next Keys
3.4 Using the PREV and NEXT keys MMI-220, 240 The PREV and NEXT keys on the MMI-220 and 240 are used to step up or down through a pre-programmed list of mes- sages called a Link. The list may be called up by putting the link message number in the MTR or by pressing a Function key. -
Page 24: Activating The Open Collector Output
3.6 Activating the Open Collector Output In addition to the beeper, the MMI-2xx series also contains an Open Collector Output. To use the Open Collector Output (O.C.), a constant must be sent to a defined register in the PLC. The Open Collector Output is a small transistor device that can be turned on to trip an external relay that could sound an external sound- ing device, etc. -
Page 25: Mmi Response
3.8 MMI Response The MMI is limited in its response to key presses and information update by the serial communications to the PLC. The MMI has been optimized to provide reason- able response times to events. 3.8.1 Response Time to Message Calls, LED, Beeper and O.C. Output Activation A message number must be in the MTR or bit sequence change in the LED register for at least 300 milliseconds to be recognized by the MMI. -

Page 27: Commonly Asked Questions
4.3 Commonly Asked Questions Q. Can I have multiple MMI’s connected to one Controller? A. The ability to connect more than one MMI to a PLC depends on the type of serial interface the PLC has. PLCs with RS232 communications cannot be net- worked due to the nature of RS232 signal requirements. -
Page 28: Repair And Return Policies
The MMI does not require any “Routine Maintenance” by the user. If a problem should occur, and all troubleshooting procedures have been exhausted, contact your local representative or distributor.
