Omron Compact Solution case study collection-the total solution for winding machine

Strip and roll machine is the a plurality solution of solution sliver drafting, and synthetic cotton net, were divided into two groups to pull out of the superposition of two layers of cotton nets, pressed in the special roll roller winding winding roll, winding thus winding completing the combing equipment work

Lap machine joint machine feeding part is composed of three parts, every part of the 18 to 24 sliver from sliver can lead, the conducting bar roller feeding, the cotton layer after the drafting device become net cotton, cotton net by smooth surface guide turned 90 degrees, in lose cotton platform three layers of cotton nets combined, the output roller into the pressing roller, again by roll Luo pull combed rolled into small volumes.

Omron solutions and advantages:

The control system of the machine is composed of 4.7 monochrome touch screen NT20S, CP1H PLC and 3G3MV series inverter. The inverter controls the main shaft and communicates with PLC through Modbus. Touch screen NT20S is responsible for processing the input and real-time status of process data. As a rare 4.7 in the market, the NT20S has a unique performance and reasonable price positioning, the replacement of the text of the machine is usually used in the past, in the basic development input, improve the level of equipment.

NT20S is the Omron Corporation for the design of small medium sized display control system, is a simple and practical. Resolving NT20S rate 256 x 128 points, screen maximum number of 500 pieces. The NT link 1: n at most 8 pt to control a PLC. NT20S has memory, switch self check, communication and other conditions of the state set to confirm the maintenance function of simple communication, etc., also has not reflective screen, can be replaced by the use of backlight lights to extend the use of time; even in bad conditions can also operate.

Communication protocol: MODBUS-RTU

MODBUS-RTU protocol is a common protocol in the industrial automation control system. The protocol uses RS-485 transmission, master-slave half duplex mode, the baud rate can be choose 9600bps and 19200bps., with strong anti-interference ability, high transmission rate, long transmission distance and low cost advantages, widely used for communication between PLC and frequency converter.

As long as the CP1H CPU unit installation wiring RS-422A/485 option board (or RS-232 option board), through software switch operation, will be able to CP1H as Modbus RTU master station to send a MODBUS command. If the Modbus is set up in the Modbus-RTU fixed distribution area in the DM fixed distribution area, the CP1H can be sent out from the station address, function, data, and the software switch is set up to send a Modbus-RTU instruction, and the received response will be automatically saved to the DM fixed allocation area.
