'C' Programmable Communications Module with Ethernet
MVI71-ADMNET
The MVI71 Application Development Module with Ethernet is a PLC backplane compatible module that allows Rockwell Automation PLC processors to interface easily with Ethernet protocol (Explicit Messaging) compatible devices and hosts. Devices commonly supporting the protocol include Rockwell Automation PLCs, and host HMI systems.
Features and Benefits
The ADMNET solution is a powerful module designed with both Client and Server support. This broad support enables the module to function as a data collection sub-master, or to be a powerful slave as a remote off an HMI host. Applications for the module are found in most industries, especially Manufacturing, Oil and Gas, Electrical Power and Food processing.
The MVI71-ADMNET module is a single slot, backplane compatible solution for the Rockwell Automation PLC platform. This module is a powerful and programmable solution supporting two fully isolated serial ports and one Ethernet port allowing the many field devices to be integrated into the PLC platform.
General Specifications
- Single Slot - 1771 backplane compatible
- The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
- Ladder Logic is used for data transfer between module and processor.
The MVI71-ADMNET module is the ideal solution for many applications where Ethernet and serial connectivity must be added to a PLC platform. Applications using the MVI71-ADMNET module include:
- Bar Code Scanner interface
- Legacy ASCII protocol connections
- Terminal Port Emulation
- Printer Driver (Alarm/Status printer)
- Customized protocol implementations
Functional Specifications
The MVI71-ADM API Suite allows software developers access to the top layer of the PLC backplane and serial ports. The MVI71-ADMNET API suite accesses the Ethernet port.
Both APIs can be easily used without having detailed knowledge of the module's hardware design. The MVI71-ADMNET API Suite consists the Ethernet Port API. The Ethernet Port API provides access to the Ethernet network. Applications for the MVI71-ADMNET module may be developed using industry-standard DOS programming tools and the appropriate API components.
The MVI71-ADMNET module has three serial ports, two of which are isolated for field interfaces, and one Ethernet port.
- CFG -- debug/configuration -- RS-232
- PRT1 -- Application -- RS-232, RS-422 or RS-485
- PRT2 -- Application -- RS-232, RS-422 or RS-485
- Ethernet Port
- PRT1 and PRT2 are jumper configured for direct or Multidrop field communication. The application program can be written to control the two application ports independently, allowing maximum flexibility in the design.
General Protocol Specifications
Allows software developers to access Rockwell Automation backplane and Serial/Ethernet ports without needing detailed knowledge of the module's hardware design
- API library functions are specified using the C programming language syntax
- Supports multi-threaded applications
- The following compiler version is compatible with the MVI module API:
- Digital Mars C++ 8.49
