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 assigned to a specific register, allowing access to its stored data. The address acts as a reference point to the location of memory within a device.

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…

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…

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…

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 from, or write Modbus data to, other Modbus TCP devices.
