Page 5: Getting Started
1.0 Getting Started 1.1 What is the MMI 1XX Series? MMI 1XX Series The MMI Series are small interfaces for PLCs. They display messages that are preloaded into them with a Personal Computer. They have 8 legendable keys, which can be programmed to perform various functions. 2x20 or 4x20 DISPLAY Equipment Checklist... -
Page 6: 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 and relays, and any other source of electrical interference are located away from the back of the unit. -
Page 7: Environmental Considerations
Standard Put the MMI through the panel cut out. Slide the Clamping frame over the Mounting case until the clips snap into the retaining slots. Tighten the clamping screws in an even pattern until the MMI is secured in the panel. Slide the Bezel frame over the case. -
Page 8: Power Connections
2.2 Power Connections Make sure that all local and national electrical standards are met when the installing the MMI. Contact your local authorities to determine which codes apply. 2.2.1 Power Requirements Power The MMI can be powered by DC power only. The specified voltage range is +12 to 27 Volts DC. - Page 9 Power supplies with large capacitive outputs may cause problems if Caution Power power is cycled within a short time period. The power supply’s Cycling capacitor will supply enough current to keep the microprocessor running for a few minutes but not enough to keep the display active. If full power is restored during that time the microprocessor may not initialize the display module.

Page 10: Grounding Requirements
2.2.2 Grounding Requirements Chassis ground must be used. DC ground (Terminal 2) is not directly coupled to Earth ground internally. It is preferable not to ground DC negative return to chassis ground, pin 3, 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 11: Safety Guidelines
2.2.4 Safety Guidelines This section presents recommended installation practices, and procedures. Since no two applications are identical, these recommendations should be considered as guidelines. Hardware WARNING! Considerations The system designer should be aware that control devices in Programmable Controller systems can fail and thereby create an unsafe condition. -
Page 12: Communications Connections
PLC or external device (Controller Connector). Different cables are required for various devices. The KEP part numbers Cable have the SMIC prefix. Refer to a KEP catalog or datasheet for a complete Requirements listing of MMI-1XX compatible devices. -
Page 13: Connection To A Personal Computer
2.3.2 Connection to a Personal Computer The 9 Pin Female connector closest to the power connector on the back of the unit is the programming port (PC Connector). Connection This port can be attached to a Computer via a DB9 Male to DB9 Female straight through cable. -
Page 14: Ce Requirements
2.4 CE Requirements 2.4.1 EU directives that apply to the MMI-1XX Series: • EMC Directive (89/336/EEC, 92/31/EEC, 93/68/EEC) electromagnetic emissions and immunity • Low Voltage Directive (73/23/EEC, 93/68/EEC) electrical safety • Machinery Directive (89/392/EEC, 91/368/EEC, 93/44/EEC, 93/ 68/EEC) machine safety MMI products will be CE-marked to indicate compliance with the EMC Directive. -
Page 15: General Safety Guide Lines For Eu Installations
2.4.3 General Safety Guide Lines for EU Installations. • Only qualified personnel should be allowed to specify, apply, install, operate, maintain or perform any other function related to MMI products. Qualified persons are defined as follows: System application and design engineers who are familiar with the safety concepts of automation equipment. -
Page 16: 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) and displays the corresponding message. 3.1 The Message Queue Occasionally messages are called up faster than they can be displayed. -
Page 17: Alarm Messages
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 3.2 Alarm Messages You can define up to 32 alarms. -
Page 18: Using The Function Keys
Description of alarm operation Triggering a message Bit 1 of alarm register one is assigned message #34, which reads This is a test message. Bit 5 of alarm register one is assigned message #35, which reads The phone is ringing. Bit 2 of alarm register two is assigned message #36, which reads An alarm message. -
Page 19: Entering Numerical Values
3.3.3 No message is assigned to the Function key. When the Function key is pressed, nothing happens. 3.4 Entering Numerical Values MMI-110 The MMI-110 & 140 may have data or bit status embedded in messages for MMI-140 the purpose of editing. Such data is usually machine status, setpoints and other setup parameters that may need to be changed from time to time. -
Page 20: Using The Up And Down Arrow Keys (Mmi-110 &140 Only)
3.5 Using the Up and Down Arrow keys (MMI-110 &140 Only) The Up and Down Arrow keys on the MMI-110 & 140 are used to step up or down through a preprogrammed list of messages. The list may be called up by the PLC or by pressing a Function key. The message will stay on the display until a new message is called by the MTR, Function Key press or one of the arrow keys is pressed. -

Page 22: 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 networked due to the nature of RS232 signal requirements. -
