Data Entry / HMI

Use 3 Pushbuttons connected to 3 Digital Inputs and LCD for feedback:

Button 1: Select parameter
Button 2: + (Increment)
Button 3: - (Decrement)

Advantages:	Low cost. Great for occasional adjustment of parameters.
Disadvantages:	Use up 3 D/I.

Use 1-10KW Potentiometer connected to an Analog Input - scale the input readings (0-4096) to fit the desired range for the parameters. A marked dial can provide a rough indicator of the settings, but if you have an LCD display then you can obtain very precise settings.

Advantages:	low cost. Easy to adjust.
Disadvantages:	Use up 1 analog input per parameter.

Use the MD-HMI Module (T100MD+ Only)*- This new product comprises one 4 lines x 20 characters backlit LCD display; a 16 keys keypad and 8 LEDs. This module is plugged into the LCD port and the expansion port of the PLC. It does not use up any of the PLC's I/O. The keys and the LEDs appear as expanded I/Os to the CPU.

Advantages:	Numeric keypad data entry is much easier. Professional looking front bezel.
Disadvantages:	Works only on T100MD+ model.

Serial Port Based HMI

All the T100MD and MX families of PLCs support mutiple communication protocols, including both the MODBUS and OMRON C20H protocols on both their RS232C and RS485 ports. Hence the PLC can work with a wide variety of third party HMIs and SCADA software that speaks MODBUS or OMRON protocols via the RS232 or RS485 port. The following are just some of those we have tested or known to work with our PLCs, Any HMI or SCADA that supports generic MODBUS devices should work with the M-series PLCs.
