20. for understanding the operation of the MVI46 MNETC module About the MODBUS TCP Protocol MODBUS is a widely used protocol originally developed by Modicon in 1978 Since that time the protocol has been adopted as a standard throughout the automation industry The original MODBUS specification uses a serial connection to communicate commands and data between client and server devices on a network Later enhancements to the protocol allow communication over Ethernet networks using TCP IP as a wrapper for the MODBUS protocol This protocol is known as MODBUS TCP MODBUS TCP is a client server protocol The client establishes a connection to the remote server When the connection is established the client sends the MODBUS TCP commands to the server The MVI46 MNETC module simulates up to 30 clients Aside from the benefits of Ethernet versus serial communications including performance distance and flexibility for industrial networks the MODBUS TCP protocol allows for remote administration and control of devices over an Internet connection It is important to note that not all Internet protocols are implemented in the module for example HTTP and SMTP protocols are not available Nevertheless the efficiency scalability and low cost of a MODBUS TCP network make this an ideal solution for industrial applications ProSoft Technology Inc Page 61 of 84 August 27 2009 MVI46 MNETC SLC Platform Reference Modbus TCP IP Communication

Client Module User Manual The MVI46 MNETC module acts as an input output module between devices on a MODBUS TCP network and the Rockwell Automation backplane The module uses an internal database to pass data and commands between the processor and the server devices on the MODBUS TCP network 5 2 2 Backplane Data Transfer The MVI46 MNETC module communicates directly over the SLC backplane Data is paged between the module and the SLC processor across the backplane using the module s input and output images Typical updates are in the range of 1 to 10 milliseconds This bi directional transference of data is accomplished by the module filling in data in the module s input image to send to the processor Data in the input image is placed in the M1 file in the processor by the ladder logic The processor inserts data to the module s output image to transfer to the module The module s program extracts the data and places it in the module s internal database The following illustration shows the data transfer method used to move data between the SLC processor the MVI46 MNETC module and the Modbus TCP IP Network SLC Processor MVI46 MNETC Module Status Data files Read Data files Ethernet Network sol LIN Write Data files 91607 seppeq saaug aue dyoeg seqeeq O Special Blocks Control files All data transferred between the module and the processor over the backplane is through the M1 file Ladder logic i
