HMI Touchscreens

ORMEC’s MMI-320 and MMI-640 flatpanel touchscreens provide a variety of sizes and functionality for human-machine interfaces. MMI-320/640 units are available in six, eight and ten inch screen sizes (diagonal), with TFT color displays.

The MMI-320/640 touchscreen is designed to provide the operator an effective way to control machine operation. The operator can easily be alerted to machine alarms and status conditions. Different panels can be quickly selected to present different sets of machine functions typically found for setup, maintenance, changing product runs and fault conditions. Operator control functionality can be built into the MMI-320/640 representing a typical factory operator panel, without the bulky hardware, I/O modules and wiring needed to build it.

Each individual panel can be designed and built in minutes using the “drag and drop” graphical objects found in the EasyBuilder application development utility. EasyBuilder includes a library of standard shapes to select from, as well as the ability to use bitmap images, when creating various panel objects. When upgrading a machine, the “look and feel” of an existing physical panel can be maintained to reduce operator retraining. After the design and installation of an MMI-320/640 is complete, its flexibility allows the designer to easily add and change control functions without having to physically add switches, legend plates, I/O modules and their associated wiring.

MMI-320/640 touchscreens include built-in recipe management, allowing for easy storage and retreival of machine setup parameters. Having this powerful capability in the HMI eliminates the need for developing recipe management in the machine control application program, saving software development time and simplifying the system design.

Each MMI-320/640 unit is shipped with the latest revision of the EasyBuilder development software and a development communications serial cable. This insures that the customer has the software and cabling necessary to properly install and configure their HMI.

Operation

Communications with an SMLC controller can be through either a serial connection using Modbus RTU, or Ethernet using Modbus/TCP. Screen objects are tagged to input and output registers that are mapped to input and output variables in the CoDeSys application program running on the SMLC. Touching a screen object, or entering data, sets the state of the variables in the SMLC application program. How the change of state is used in the program defines the object’s control function.

LED Indicators

Each HMI-320/640 unit has three status indicator LEDs to assist with installation and troubleshooting.

• PWR - Indicates the unit has power.
• CPU - Indicates that the processor is operating properly.
• COM - Flashes during serial communications.

CE Mark

All HMI-320/640 units are CE Marked, indicating compliance with European Union directives EN 55011: Group 1, Class A; EN50081-2 (Also US FCC Class A) and EN50082-2.
