Force Download Mode for MLCs: In case the PLC is not responding for the firmware download command and when it does not allow the further download in the unit, PLC can be driven in the Force download mode. Follow the following step to enter the force download mode. Power off the unit Remove all communication cables. No…

There are multiple ways to toggle a bit in MAPware7000, One option is to use the Toggle bit in the “Quick Buttons” menu or the Toggle bit task available for screens and task buttons. Another option is to use logic. If you want to use a momentary input, as seen in the figure below, to…

In the Native Ladder programming environment, there are multiple ways to set a bit. One option is to set a bit from the screen using buttons and tasks. Another option is to use logic. You can use the following logic to create the latch: The Device Set and Reset instructions (Special Instructions > Data Processing) to…

Method 1: The GetData and SetData functions can be used to transfer data from one tag to another in a macro. Use GetData to grab the value from one tag and store it in a variable, then use SetData to move the data from the variable into the other tag. Use the Get/Set FN tool…
Read More How to transfer data from one PLC to another using the HMI, or from PLC to HMI.
The issue could be related to the firmware version on the PLC. Currently, Get Tag Info seems to work with firmware v20 and v24 but not anything higher. If this is the case we recommend importing the tags using the *.L5K. Instructions to do this can be found in this Help Topic.
May be related to the DPI setting on the Windows PC. Set it to “Smaller – 100%.”
In order to open a MAPware7000 project, you will need both the .mpl project file and the folder with the same name (which will be in the same directory that the project was saved when it was created).
The Word Lamp Object is used as an indicator to represent the value in a PLC register, or the value in a register in the HMI local memory (LW). Creates a graphics object to reflect the current state of a multi-state PLC data register. It can display a different shape or picture depending on the…
Setting up communication between a Maple Systems HMI and Maple Systems PLC is easy. We created a step by step tutorial showing you how to set up Modbus RTU and TCP communications.
This is the specific purpose of the cMT Gateway devices, but the HMIs and other cMTs can also perform this action in a different way. In EBPro you can use the Macro feature with the GETDATA() and SETDATA() functions to fetch the data from one tag or address range on one device and write it…
Read More How can I transfer data (mapping tags / addresses) from one PLC to another using the HMI?
Yes, our Maple Systems brand Micro PLCs and Modular PLCs use our free PLC programming software (MapleLogic) and can easily integrate with our HMI/cMT products via ethernet or serial cables, using common communication protocols such as a MODBUS TCP/IP or MODBUS RTU. This Tutorial will step you through how to Set Up your Maple PLC…
Read More Can I pair a Maple Systems HMI with a Maple Systems PLC?
Yes. Our HMIs can be paired with our PLC products via Modbus RTU or TCP. The Modbus Slave driver is configured in the PLC software, and the Modbus Master driver is configured in HMI software (EBPro). Tags can be exported and imported in both directions.
