The Chameleon PROFIBUS Network Interface Module (NIM-7) provides seamless connectivity to PROFIBUS DP compliant devices. It features a high-performance 32-bit RISC processor with multi-tasking RTOS to execute computationally-intensive applications and to interface with other modules in the Chameleon family. Network message processing is offloaded to a co-processor containing an integrated Siemens ASPC-2 PROFIBUS controller.

Chameleon’s multi-processor architecture allows considerable flexibility in the use of NIM-7 modules. They can serve as a standalone high-end remote I/O application processor node on a PROFIBUS network with connectivity to other inexpensive (and computationally-limited) slave devices. They can be arranged with other Chameleon I/O modules to create a high-end Programmable Automation Controller (PAC) solution. Or, they can be combined with other Chameleon networking modules to create a gateway between multi-protocol network segments or to create a bridge between multiple PROFIBUS segments (using the internal high-speed backplane to transfer data between modules). For example, the NIM-7 module can operate alongside a NIM-1 Modbus module, or NIM-6 LonTalk module, or NIM-2 Ethernet module executing a supported IP protocol (e.g. EtherNet/IP or PROFINET) to transfer data between networks.

You program the NIM-7 with the Design Pad graphical configuration tool. Design Pad G3 enables you to create sophisticated remote control, local control, monitoring, and/or network message handling applications without prior programming experience. It also contains an integrated PROFIBUS network configuration tool with GSD import, as well as integrated off-line device network simulation capabilities for both Fairmount Automation devices and third-party products.

The NIM-7 operating-mode (master or slave) is software-configured—the module takes on the selected role during its initialization sequence. Using the same module for both functions can provide measurable logistics benefits and reduce procurement, maintenance, and training costs.

The firmware in all Chameleon modules can be updated in the field as new software features are released. For example, new PROFIBUS extensions (e.g., DPv2) could be added to the NIM-7 as they become available in the future, thereby protecting today’s hardware investment from obsolescence.

As with all Chameleon modules, NIM-7 units are hot-swappable: when a new module is inserted into a Chameleon node, its neighboring modules automatically transfer the program it is to execute—there is no need to shut off the power or to detach connectors. They also provide unequaled ruggedness. They are specifically designed for sustained operation in severe environments, including those characterized by extreme shock, vibration, electro-magnetic interference, temperature, and/or humidity. The fully-sealed enclosure (sealing end-caps not pictured) allows the module to operate while submerged.
