3 According to the different hardware structure, PLC could be divided into host unit, expansion module and BD board.
4
5 WECON PLC has the built-in battery, CPU and I/O points. The PLC CPU could connect with I/O expansion modules to expend the I/O point number or connect with some special function expansion modules.

64 The PLC CPU and the expansion module are the same size in height and depth, but different width. So they could connect with each other in a neat form, also the configuration is flexible.

Leo Wei 1.1 72
Karen 8.1 73 Compared with expansion module, BD module is smaller, more flexible (up to 2 BD modules in one PLC) and cheaper, but also with multi-function. Because the BD module is installed in the host unit, so it will not occupy extra space.

89 Mount the plc in the DIN (35mm) rail directly. Gently pull out the DIN rail mounting clip from below, then we could remove the main unit from DIN rail. The mounting holes could be used to directly mount the programmable controller with M4 screws. Please refer to the following table for the pitch and location of mounting holes.

143 1. The 1S instruction set does not support floating-point operations.
144 1. The LX3V series of Wecon PLC is the basic model.
145 1. The LX3VP series is an upgraded version of the LX3V series, which adds N:N network communication function, RSLIST tabularization, DVIT interrupt positioning instruction, PLSR2 multi-speed high-speed instruction, and supports ETH-BD (Ethernet module) and CAN module.
146 1. The LX3VE series is an upgraded version of the LX3V series, which adds electronic cam, S-cam function, N:N network communication function, linear interpolation function, RSLIST table command, DVIT interrupt positioning command function, and supports ETH-BD (Ethernet module) .
147 1. The LX3VM series is an upgraded version of the LX3VE series, which adds the arc interpolation function, but does not support ETH-BD (Ethernet module).
