MDA Scientific System 16 Slave Module
MVI56-MDA16
The MVI56 MDA Scientific System 16 Gas Analyzer Slave Module allows Rockwell Automation ControlLogix processors to interface easily as a host with MDA Scientific CM4 gas monitoring hardware (See MVI56-MDA4 for a CM4 solution).
Features and Benefits
The MVI56-MDA16 module acts as an input/output module between the System 16 network and the Rockwell Automation backplane. The data transfer from the ControlLogix processor is asynchronous from the actions on the System 16 network. A 1600-word register space in the module is used to exchange data between the processor and the System 16 network.
General Specifications
- Single Slot - 1756 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. Sample ladder file included.
- Configuration data obtained from configuration text file downloaded to module. Sample configuration file included
- Local or remote rack
Applications
This application is useful for any industry producing, using, or exposed to toxic or corrosive gases, where interfacing the System 16 Gas Analyzer with a ControlLogix processor is required.
Functional Specifications
- Support for the storage and transfer of up to 1600 registers to/from the ControlLogix processor's data files
- Two System 16 slave ports.
- Configurable parameters include:
- Baud Rate 110 to 115,200
- Parity None, Odd and Even
- Data Bits 5 to 8
- Stop Bits 1 or 2
- RTS On and Off Timing 0 to 65535 milliseconds
- Use of CTS Modem Line Yes or No
Operating Specifications
The MDA-16 product includes the following standard features:
- Two fully configurable serial ports, each capable of supporting the System 16 Slave functionality
- Supports one System 16 unit per serial port, 2 total per module
- Memory mapping will be pre-defined in the module to ease implementation in the ladder program
- RS-485 connection from each port directly to the System 16 unit
