Mitsubishi have introduced the E100 Human Machine Interface (HMI) for text applications featuring two 20 character lines of 5mm high text displayed on a backlit LED panel.
Recipes can be created using the keypad or uploaded from a PC and can be saved under a user-defined name; this feature makes the unit ideal for processes that use more than one parameter setting on a regular basis. The internal real time clock allows switching of lights, fans and pumps on a weekly schedule via digital signals.
The unit needs a 200mA, 5V DC power supply which can be external or taken from a PLC port. Programming and monitoring of any Mitsubishi PLC can be carried out during run time with the HMI in transparent mode without disconnecting the operator terminal using RS232 and RS422 serial ports. Connection is possible to Siemens S5/S7, Allen Bradley DF1 or DH485, Omron hostlink and GE Fanuc SNPX and the unit supports Modbus and Comli networks.
Other features include the HMI unit’s keyboard which has four function keys that can be configured either as local or global keys and keyfields on the screen give the operator information about the assigned function. Individual objects and screens are protected by an eight level password system by pressing a function key and typing in the password.
