'C' Programmable with Ethernet Modbus Master/Slave
5201-ADMNET-MCM
Product Description
The ProLinx 'C' Programmable Application Development Module with Ethernet to Modbus Master/Slave creates a powerful platform for developing and running 'C' applications to communicate with Modbus Master/Slave networks and devices. The module provides four serial ports, each individually configurable as a Modbus or custom Master or Slave.
ADMNET Protocol Specifications
The ADM API Suite is provided to allow software developers access to the top layer of the serial ports. The ADMNET API suite accesses the Ethernet port.
Both APIs can be easily used without having detailed knowledge of the module's hardware design. The ADMNET API Suite consists the Ethernet Port API. The Ethernet Port API provides access to the Ethernet network. Applications for the ADMNET module may be developed using industry-standard DOS programming tools and the appropriate API components.
The Modbus (MCM) protocol driver supports Master and Slave implementations of the protocol. All Modbus serial ports are individually configurable, providing a very powerful and flexible host or device interface solution.
Product Applications
The 5201 ADMNET-MCM module is the ideal solution for many applications where Ethernet and serial connectivity need to be added to a Modbus Master/Slave platform. Example applications involving the 5201 ADMNET-MCM module include:
-
Bar code scanner interface
-
Legacy ASCII protocol connections
-
Terminal port emulation
-
Printer driver (alarm/status printer)
-
Customized protocol implementations
Functional Specifications
Internal Database
The ProLinx module contains an internal database that can be configured as needed to handle your data transfer.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
General Protocol Specifications
- Allows software developers to access 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 versions are compatible with the MVI module API:
- DigitalMars C++ V8.49
- Borland C++ V5.02
- Operating System - General software DOS 6-XL
- Flash ROM program space: 896 KB
- RAM program and data space: 640 KB
- Compact Flash socket: Up to 64 MB
ADM API Libraries
Each API provides a library of function calls. This library supports any programming language that is compatible with the Pascal calling convention.
- Initialization - Open and close the API
- Debug Port - Debug port user interface
- Database - Read and write data to database
- Timer - Start and check timers
- Backplane - Transfer data over the backplane
- LED - Set user LED indicators
- Flash - Parse configuration files
- Miscellaneous - Configure the console
Modbus Protocol Specifications
The Modbus driver provides access to an internal database of 4000 registers (words), with extensive support provided for both the Master and the Slave implementations of the protocol. The serial port(s) on the gateway can be individually configured to support the Modbus protocol (Master or Slave, RTU or ASCII, Baud Rate, etc).
