2. System Settings

Select ‘LS Industrial Systems Co., Ltd.’ for ‘Manufacturer’ and ‘Master-K Series Cnet’ for ‘Series’ in the ‘Add

Device/PLC’ setting window.

Add a device and set up a port to the device and a communication type.

The weMX® N series support as below.

COM weMX®N Series

COM1 RS-232C

COM2 RS-232C

COM3 Do not use ( Debug Port)

COM4 RS-485(2 wired)

Set up the selected COM port interface to the device.

Items Description

Speed Select one: ‘2400’, ‘4800’, ‘9600’, ‘19200’, ‘38400’, ‘57600’ and ‘115200’.

Data Length Select ‘7’ or ‘8’.

Parity Select one: ‘NONE’, ‘EVEN’ and ‘ODD’.

Stop Bit Select ‘1’ or ‘2’.

Flow Control No supported

Timeout Standby time for communication. (Unit: seconds)

Retry The number of attempts to communicate after a failure.

Wait to Send Time to wait before sending a message to the external device (Unit: milliseconds)

- This is the time required to wait every time before sending to the device.

Delayed

Interval

This is the time required to wait after the external device finishes reading values for

addresses to the screen. (Unit: milliseconds)

- Start to read those values again after waiting as long as delayed intervals.

PLC’s Manual|5

V1.5

Set up a unit ID to the added device. It indicates a station number in case of LSIS. The default value is ‘0’.

If the device’s station number is different, change it by clicking a unit ID displayed button, ‘Unit ID’ button.

Items Description

Default Unit ID Set up the station number. The default value is ‘0’ The range is from ‘0’ to ‘31’.

Click ‘ ’ button to finish setting up the rest features.

Items Description

BCC Tick ‘BCC’ if it is used for communication between devices.
