Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network.
Maple Systems cMT and HMI products can bridge the gap between your SCADA system and field devices. Using the HMI’s Modbus RTU/TCP Slave protocol, the Modbus Gateway provides a mechanism to connect the Modbus RTU/TCP Slave protocol to storage within the HMI or in a connected device. The SCADA system uses the Modbus TCP Master…
Yes, Maple Systems HMCs (HMI + PLC) can be configured to act as a Modbus Master and/or a Modbus Slave. For step-by-step instructions on how to set up this communication and use tags in your project refer to Tech Note 7016, “Modbus Communications in MAPware-7000”.
The MAPware-7000 Modbus Tag Converter Utility will take an exported Native Ladder MAPware-7000 tag file and convert the register addresses to their Modbus Slave addresses in a format that can be imported into EBPro (our HMI Programming Software). The conversion utility can be found in the Maple Systems Technical Support Center, under Software Downloads &…
Yes. Ethernet HMI+PLC models allow you to create Web Screens which are accessible through a web browser on the local network. Additionally, you can pair one of our cMT Gateway products with a Maple Systems HMI + PLC (HMC) unit to add remote data access and enhanced data extraction. The cMT Gateway uses Modbus TCP…
Absolutely. Maple Systems PLCs can communicate with an HMI + PLC (HMC) either with or without I/O modules attached to it. A potential application would be to have the PLC installed in a remote cabinet, while the HMC is mounted in a convenient location for the operator. With the HMC optional I/O modules, local control…
