If your PLC powers on, and indicates that it’s in “stop” mode via the LEDs on the unit, but the “error” LED is off, then it’s likely that the physical “run/stop” switch on your PLC is set to “stop” mode. This FAQ demonstrates how to locate the switch on the PLC that will change this…
These instructions detail how to transfer a MapleLogic project file to a different directory or device. In order to open your MapleLogic project properly after the transfer, you will need the *.PLC file, as well as all of the files next to it: So in order to properly transfer this full project, we’ll need to…
To find the default IP address of your new PLC, and to change its IP address, first click the red Parameter folder in the project window menu in MapleLogic, then click PLC Parameter. Then, in the PLC parameters, click the Ethernet tab. You will see the default IP address set to 100.100.100.100. This is the…
A layer 3 network switch operates at the Network Layer of the OSI model. Click here for more information about the OSI Model. Layer 3 network switches forward data based on IP addresses. Unlike layer 2 network switches, layer 3 switches route traffic between different subnets. These switches combine the features of a traditional router and a…
A layer 2 network switch operates at the Data Link Layer of the OSI model. Click here for more information about the OSI Model. Layer 2 network switches forward data based on MAC addresses. They are responsible for directing traffic within a local area network (LAN). Layer 2 switches do not inspect IP addresses, and…
The Open Systems Interconnection (OSI) model is a reference model which describes seven layers of communication between computing systems over a network. These seven layers are as outlined: The OSI model was developed by the International Organization for Standardization. It describes the tasks required to transmit data via radio waves, light, or electricity.
MapleLogic has the ability to run a project file in simulation mode for testing purposes. Simulation mode uses the computers loopback address of 127.0.0.1. The loopback address connects to the local computer and simulates PLC operations. This can help verify logic before deployment to actual hardware.
In MapleLogic registers store data used for control logic and operations. They hold values such as integers or bits. Registers are essential for monitoring inputs, and controlling outputs. Common register types include discrete, word, timer, counter, and floating-point. Below is a diagram of available Registers, their description, and if they can read or written to/from.
Ladder Diagram, a graphical programming language, is used to design logic for PLCs. Maple Systems Inc. MapleLogic PLC programming software utilizes Ladder Diagram, LD for short. Each rung represents a specific control operation with inputs and outputs arranged in sequence. Ladder diagrams are standardized by the International Electrotechnical Commission (IEC), specifically under IEC 61131-3. The…
MapleLogic utilizes logical control operations in a ladder diagram called a “rung”. Each rung contains inputs and outputs. Inputs are usually sensors, switches, or conditions that control output devices. Rungs evaluate from left to right activating outputs based off condition parameters.
MapleLogic is a software suite owned by Maple Systems Inc. It is a robust programming software for Maple Systems Micro and Modular PLCs. It programs PLCs to communicate to sensors, switches, motors, HMIs, and more over serial or ethernet. MapleLogic utilizes Ladder Diagram, a graphical programming language, which place logic elements onto rungs on a…
A register address in EasyBuilder Pro refers to a specific memory location used to store and manage data within a system. A register is a specific storage location, typically in memory or a device, used to hold data for processing. They often are categorized as internal or external registers. An address is a unique identifier…
