turn Modbus Profinet gateway to control the main object is the gas blower, bar machine, as well as the control and the field of steam parameters, display and alarm system is the main choose of Siemens S7-1200 PLC, through ET200 IO module control field devices and monitoring data, the inverter adopts the British witten CHF100A frequency converter, the British witten CHF100A inverter access gateway of Siemens S7-1200 using Emerson turn Modbus Profinet gateway MCN - PN3001, this article mainly about the turn Modbus Profinet gateway configuration process, first of all to join the GSD file, transfer the Modbus Profinet PN3001 GSD file copy of the gateway in any position, open the bo figure, create new project "the British witten", enter the devices and networks, stood options in the management of general description file, install the GSD file,
Select MODBUS turn PROFINET gateway MCN - PN3001;
Transfer the Modbus Profinet gateway configuration to Profinet network
Set turn MODUS PROFINET device name and IP address of gateway in PROFINET network
Confirm the total number of frequency converter used parameters according to the quantity, and the corresponding data length is added in the configuration
Choose to write command is needed here, read a; Which is 4 bytes output, 2 bytes input
After the completion of the configuration Settings to download to the PLC, and start to configure the Modbus parameters Settings,
Turn first to install the Modbus Profinet gateway MCN - PN3001 configuration software
Open the software new project:
Choose PN2MM
Configure the IP address of the gateway and the device name (to be consistent with the configuration software)
Setting up the Modbus parameters (output command polling mode according to the need to select a single to send, send in a row, pulse, etc.)
Fill in the inverter station number
This is the first article, need to write the data, the starting address of 1000 h, the decimal is 4096
Function code according to the frequency converter set to choose 6 function code is to write a single register
Register according to the decimal format in 1000 h 4096
The memory mapping the starting address for the default 1500, corresponding to the Q address DiYiErGe bytes
This is the second article, need to write the data, the starting address of 2000 h, the decimal is 8192
Memory mapped before starting address for a command of the two bytes so 1502 corresponding Q address here three or four bytes
This is the third article, need to read the data, the starting address of 1001 h, the decimal is 4097
Choose 03 function code is read more registers, address fill in decimal 4097, register number 1, memory mapping address 0 corresponds to the I DiYiErWei
After configured via USB download to turn the MODBUS PROFINET gateway MCN - PN3001, after electrical connections on the PLC and frequency converter,
Above is wuxi Modbus Emerson turned Profinet gateway configuration process of MCN - PN3001
