Is there an Audio feature on my HMI?

Yes, most Maple Systems HMI display units have a transducer capable of sounding beeps. Select models have standard line-level output for driving amplified speakers via a standard 1/8-inch mini connector to play .wav files (review product specifications for model compatibility). This is useful for playing alert sounds when an alarm or event is triggered. Audio…

I received a “registration is required” message. Why am I being asked to register my software?

In the past, Maple Systems required customers to pay for a license and complete a registration process during installation in order to use our software. We now offer all our software for free and no longer require you to register. This includes EBPro, MAPware-7000, MapleLogic and other legacy programs. However, while you are installing our…

What is CANbus?

Originally developed for use as an in-vehicle network in passenger cars, nowadays Controller Area Network (CAN) is used in many other industries. This includes applications in any kind of transportation system (rail vehicle, aircraft, marine, etc.), in industrial machine control systems, in home and building automation (e.g. HVAC, elevators), in mobile machines (construction and agriculture equipment), in medical devices and laboratory automation, as well as in many other embedded and deeply embedded applications.

CAN communication protocols are based on a distributed scheme, there is no central unit, allowing a direct data transfer between any two or more CAN devices. In an automated industrial installation, CANbus is most commonly used as part of a control system connecting vital systems that may be spread throughout a facility.

A Maple Systems HMI with CANbus support, allows the operator to interact with the system. From there programmable logic controllers (PLCs) relay those commands through the CANbus interface to the sensors, actuators, motors or other mechanical systems that carry out the desired action.

What is IEC 61131-3?

IEC 61131-3 is a section of an International Electro-Technical Committee (IEC) standard that provides a definition for implementing PLC programming software.

The standard was first introduced in 1993 as the result of an effort to standardize the myriad PLC logic editors in the automation marketplace. The goal of the standard is to give automation professionals a familiar environment and set of tools to create PLC programs across vendor platforms.
