Noise can sometimes be introduced into a sensor input by a power supply or other high-powered equipment. Using a high-quality power supply is always a good idea. Noise on the input is seen when the input value jumps around sporadically, especially for a normally stable sensor reading such as for temperature or pressure. When there…
The MAPware-EBPro Modbus tag converter tool will not work if your application is in IEC Mode. This tool was designed for the Native Ladder (deprecated) programming mode that had pre-assigned Modbus addresses assigned each local address. If your MAPware application uses IEC mode, you must create tags in the tag database and assign Modbus…
HMI+PLC (HMC) To view the programmed Ethernet parameters of your HMC2, HMC3 or HMC7 on the network, press and hold the lower right corner of the screen while powering on. On a HMC4 series screen, press/click and hold the top left corner of the screen for 5 seconds while the device is powered on.
The first step to monitor logic in an HMC is to connect it to the PC running MAPware-7000. Several connection methods are available: USB, Ethernet, and serial. The “Online Communication Mode” in MAPware-7000 must be set to match the connection method. To do this, click on the Tools menu…Preferences…Online Communication Mode to select the connection method used…
You can easily create one by adding a BOOL tag with the initial condition of FALSE. Then on the last rung of the logic block set the bit TRUE.
In IEC mode, tags cannot be given local addresses by the user. If you delete auto-generated tags and want to get them back, open the IO configuration wizard (IO Allocation > Expansion) and reconfigure the module. Just click the dropdown menu and select the configuration that you want, even if it is already set to…
If you are wondering how you can assign tags for dynamic limits in a Numeric Object, take note of the “Usage…” note in the Object Properties window. The Numeric Object uses the tag assigned in the object properties as the Device Low limit, and uses the next sequential address as the Device High limit. For…
Yes. You can dynamically change the address referenced by an object using the index feature. This allows you to create and indirect pointer or offset into PLC or HMI memory. In the object properties window click on the address settings button then check the Index register checkbox and select the index to use: When you…
After upgrading from EZwarePlus to EBPro you may have experienced an issue were a project using this device driver worked in the former software but not in the latter. Usually, the problem happens when the parameters below are not set correctly. data-filename=”image.png” style=”width: 50%;”> Change these parameters to match those in your PLC. data-filename=”image.png” style=”width:…
Yes, the HMC can be configured as a Modbus TCP Master on COM3 and still retain the default Modbus TCP Slave configuration. You must choose one or the other between master and slave for Modbus RTU, but Modbus TCP can be both simultaneously thanks to Ethernet. As a master (client) you can read Modbus data…
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. data-filename=”MLCSerialPinout.png” style=”width: 449px;”> Power off the unit…
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…
