General Specifications
? Single-slot 1756 ControlLogix backplane compatible ? 10/100 Mbps auto crossover detection Ethernet configuration and application port ? User-definable module data memory mapping of up to 5000 16-bit registers ? CIPconnect-enabled network configuration and diagnostics monitoring using ControlLogix 1756-ENxT and 1756-CNB modules ? ProSoft Configuration Builder (PCB) software supported, a Windows-based graphical user interface providing simple product and network configuration ? Add-On Instructions (AOI) are used for data transfer between module and processor ? 4-character, alpha-numeric, scrolling LED display of status and diagnostics data in plain English – no cryptic error or alarm codes to decipher ? ProSoft Discovery Service (PDS) software used to locate the module on the network and assign temporary IP address ? Personality Module - a non-volatile industrial-grade Compact Flash (CF) card used to store network and module configuration for easy disaster recovery, allowing quick inthe-field product replacement by transferring the CF card
Functional Specifications
? Siemens Industrial Ethernet data types overlap in the module's memory database, so the same data can be conveniently read or written as bit-level or register-level data. ? Configurable floating-point data movement is supported ? Configurable parameters for the Client including a minimum response delay of 0 to 65535 ms ? Supports up to 20 Clients with up to 16 commands for each Client ? Error codes, counters, and module status available from module memory through the Clients, or through the ladder logic and controller tags in RSLogix 5000
Backplane Data Transfer
The MVI56E-SIE module communicates directly over the ControlLogix backplane. Data is paged between the module and the ControlLogix processor across the backplane using the module's input and output images. The update frequency of the images is determined by the scheduled scan rate defined by the user for the module and the communication load on the module. Typical update times range from 1 to 10 milliseconds. This bi-directional transfer of data is accomplished by the module putting data in the input image to send to the processor. Data in the input image is placed in the processor's controller tags by ladder logic. The input image is set to 250 words. Processor logic inserts data to the output image to be transferred to the module. The module's firmware program extracts the data and places it in the module's internal database. The output image is set to 248 words. The following illustration shows the data transfer method used to move data between the ControlLogix processor, the MVI56E-SIE module and the Siemens Industrial Ethernet Network.
