PLC Protocols

Maple Systems HMIs offer versatile support of 200+ controllers and are compatible with the biggest names in PLCS. Even if we don't have a proprietary protocol, we can still likely communicate with the controller using Modbus. Unlimited tags and multiple protocols are supported at no extra cost and there are no fees for runtime licenses. EZware comes with all of the communication drivers you need.

Enhanced PLC Connectivity

Graphic HMIs have multiple communication ports – both serial ports and an Ethernet port. This flexibility enables you to use one operator interface to control complex automation systems.

  • Connect any PLC of your choice to each port simultaneously
  • Connect a computer to the Ethernet port for remote monitoring

Modbus RTU and TCP/IP

The Modbus protocol is used by many different brands of controllers and drives. Our HMI configuration software has a Modbus protocol driver for both serial and Ethernet communications, offering a great deal of flexibility when it comes to networking.

Importing Tags

Unlimited tag files can be imported into our configuration software from a variety of PLCs including Allen-Bradley and Siemens. Using tags can simplify programming the HMI to work with the PLC. Tag names (i.e. Temperature, OvenTemp1, etc) are assigned to variables and data memory locations to take the place of a memory address. This is of benefit because controllers that use memory addresses are often time consuming to program ("Did I place the temperature value in register 100... or 134??").

Maple Systems HMIs offer the ability to assign a tag name to a memory address using the Tag Library and custom tag files can be created in Excel and imported into the software's Tag Library. When creating objects, the tag name can also be selected to reduce programming time and confusion.
