Allen-Bradley MicroLogix series / SLC500 series PLCs have some specific addressing format requirements for select memory locations (Bit-level and Strings, for example). Both drivers (Serial and Ethernet) follow these rules: Bit-level objects must reference the bit position to two digits! Bit 0 is 00, bit 9 is 09. For example, B3 memory, word 5, bit…
Keypads and keyboards are part of the template files included with EBPro, beginning on Window 50. When starting a new project in EBPro, make sure the “Use template” option is checked on the “New Project” window when selecting the HMI model to use. Keypads can be added or removed from the project in the System…
Quadrature encoders are used to measure both the speed and direction (clockwise or counter-clockwise) of a device. Each encoder has two tracks, A and B (thus two inputs are required), that are 90° out of phase, which enable it to provide accurate position information. It will count up when phase A precedes, and count down…
All of our Industrial PCs comply with FCC (Federal Communications Commission) Part 15, which regulates radiation from an electronic device.
Great for normal lighting conditions, our Backlit LCD (Liquid Crystal Display) Operator Interface Terminals, or OITs, are rugged and reliable. They are operable in temperature extremes ranging from -10°C up to 65°C. Features include 2 or 4-line Displays, 6 to 24-key keypads, a custom slide-in legends and are Class I, Division 2. VFD (Vacuum Fluorescent…
Unfortunately, we are unable to provide free technical support to units that were not purchased directly from Maple Systems or one of our partners. We do provide fee-based Application Engineering. If you are interested in receiving a quote on our application engineering services, refer to the Application Engineering page on our website. Or you can…
A barcode (also bar code) is an optical, machine-readable, representation of data; the data usually describes something about the object that carries the barcode. Traditional barcodes systematically represent data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D) or Aztec Code or QR Code (2D).
A device that translates a physical property into an electrical signal.
When projects are compiled in EBPro, the font files are compiled as well. When using certain fonts or displaying languages written from right to left (Arabic, for example), some fonts may not be correctly displayed your Maple Systems HMI. Refer to Tech Note 5106, “Download Complete Font,” for some possible solutions. In addition, if a…
Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network.
Security is paramount in today’s technologically advanced times and so is connectivity. Many PLCs take advantage of Ethernet communication to transmit data to a monitoring device such as an HMI. Plant corporate networks also run via Ethernet. But how do you get data from the PLC to your corporate network without the bandwidth or security…
Yes. Ethernet HMI+PLC models allow you to create Web Screens which are accessible through a web browser on the local network. Additionally, you can pair one of our cMT Gateway products with a Maple Systems HMI + PLC (HMC) unit to add remote data access and enhanced data extraction. The cMT Gateway uses Modbus TCP…
