The RMC can emulate a number of Ethernet PLC devices. A list of those supported is described in RMC Ethernet Module Overview. Any device or PC-based software package that can read and write registers in devices that the RMC ENET can emulate can most likely also read and write registers in the RMC. For example, a number of Human-Machine-Interfaces (HMI) can access registers in Allen-Bradley PLCs over Ethernet. Most of these will also be able to access registers in the RMC as well.
Similarly, any device that can read or write registers using one of the RMC's application protocols can also communicate with the RMC. For example, Wonderware's InControl PC-based control package supports a Modbus/TCP SuiteLink driver and can therefore control an RMC over Ethernet. Another example is Control Microsystems' SCADAPack PLC with the 5905 Ethernet Gateway, which supports Modbus/TCP and therefore can also control an RMC over Ethernet.
It is best to contact a Delta Computer Systems, Inc. sales engineer to discuss Ethernet devices that are not explicitly listed as compatible with the RMC. There may be subtle problems with using some devices with the RMC. For example, a device that proclaims Modbus/TCP support may only be a slave. The RMC is also a slave and therefore neither device will initiate transfers, preventing the devices from being able to work together. By talking with a sales engineer, we receive feedback on the devices our customers want to communicate with and may lead to enhancements in our documentation and device support.
