Maple Systems Certifications
Since 1983, Maple Systems has been selling OITs, HMIs, Panel PC, and HMI + PLC solutions to the automation and controls industry. Over the years we have been honored to be able to provide our customers with the latest in HMI technology. We also take great pride in knowing that many our legacy units are still out in the field after all these years.

Whether it's supporting the thousands of units we have in the field, or supplying the newest technology in automation and control, Maple Systems is Your Industrial Control Solution.

Class I

Watch and learn. We believe that learning happens in many ways, which is why we offer education and training videos on our HMI and HMI+PLC products. Our training videos offer step-by-step instructions on the most requested features and product overviews, available for you to watch at your own pace, on your own time, for free.

Alarms are handled similarly to the Sampling / Trending objects, in that they are a two-part feature: The Event (alarm) log itself is where the alarms are configured, and the Alarm Bar, Alarm Display, and Event Display Objects control how the alarms are viewed.
Most PLCs have actual, physical memory locations that can be referenced; not so with Allen Bradley CompactLogix and ControlLogix. They use Tags, which means the tag file needs to be imported in order to reference any PLC address / variable.
The other main Allen-Bradley PLCs (MicroLogix series / SLC500 series) have some specific addressing format requirements for select memory locations (Bit-level and Strings, for example).
Data Sampling / aka Data Logging is the act of logging data from a device, and Trending is the act of taking that data and showing it visually, usually via a graph. The relationship between Data Sampling and Trending is a very close, intertwined one.
Projects created for use with the original HMI500 software (EasyBuilder) can in many cases be converted – translated – for use with the newer 3rd gen software (EZPlus/EBPro). The process entails installing both the 2nd and 3rd gen software packages – EasyBuilder-5000 (EZware-5000) as well as EZwarePlus/EBPro.
In the configuration software, Local and Remote refer to the answer to this question: "Am I going through another HMI besides this one to get PLC variables?" If Yes, then the PLC is to be configured as a Remote PLC. If not, then the PLC is a Local PLC for the purposes of the configuration software.
The PLC No Response popup window is the main method of letting the HMI operator know there's an issue. If it pops up on every HMI window, then the issue is likely a global one. If it pops up only on one or two screens, then it is likely an addressing issue within an item on one of those windows.
Recipes can be created one of two ways – directly accessing the recipe memory area, or creation of a Recipe Database to hold the recipe data. The Recipe Database is supported in all HMI series except Basic HMIs.
There are two methods of user security in EZwarePlus/EBPro: General and Enhanced Mode. General mode is for the majority of users, where a simple user number and numeric password will suffice. Enhanced security is for adding users dynamically to the HMI, adding temporary users, and passwords with alphanumeric/special characters.
There are several ways to upload or download projects, depending on what you're working with. The process is the same, no matter what: Upload/Decompile/Download.
