WECON PLC has high speed input counters, high speed counters have selectable count directions.
Counters list
The following device table outlines the range of available high speed counters on both the LX3V PLC.
LX3V PLC X0 and X1 support up to 200KHZ. X2~X5 support up to 10K HZ.
The LX3V-4AD special module has four input channels.The input channels receive analog signals andconvert them into a digital value.This is called an A/D conversion, the maximum resolution is 12 bits.
The selection of voltage or current based input/output is by user wiring.Analog ranges of -10 to 10V DC (resolution:5mV), and/or 4 to 20mA, -20 to 20mA(resolution:20µA) may be selected.
Data transfer between the LX3V-4AD and the LX3V main unit is by buffer memory exchange. There are 32 buffer memories (each of 16 bits) in the LX3V-4AD.
LX3V-4AD consume 5V voltage from LX3V main unit or active extension unit,90mA current of power supply.
It adds two analog inputs and two analog outputs. The module is mounted on top of PLC, so there is no need to change the PLC installation area.
Digital to analog conversion is performed by PT100 in LX3V-2PT2DA-BD, and the converted digital value is stored in a special registers. However, the characteristics of the analog to digital converter can not be adjusted. Address assignment in the following table.
WECON PLC can achieve position function by some commands. This demo use PLC to control one step motor.
WECON PLC could support floating calculation, which could meet more requirements. In this demo, WECON PLC communicate with WECON HMI, and it do a simple floating calculation.
1. General
WECON LX3V Series PLC could support MODBUS RTU protocol, users could use COM2 for communication.
2. Protocol Setting (D8126)
3. Communication Format (D8120)
1. General
The timer is used to perform the timing function. Each timer contains coils, contacts, and counting time value register. When the coil sounds (with sufficient power), the timer starts timing. If the timer’s registered value reaches the preset value, the contacts activate, and other contacts (NO contacts) are closed, while b contacts (NC contacts) disconnect. If the coil power shuts off (insufficient power), the contacts will restore to their initial states and the value will automatically be cleared. Some timers have the feature of accumulation and shut-down. After a restart, it will even keep the value before the shut–down.
2. Timer list
Timers have different timing steps. For instance, 1ms, 10ms, 100ms, and etc. See the following:
3. Program
This is a simple demo for timer in LX3V PLC. In this demo, Y0 will be ON for 3min and OFF for 1min, when M0 set ON.
1. General
This instruction is a communication transceiver instruction. It sends the data in specified register to the serial ports automatically, and store the data to the designated area. This is equivalent to that the user program accesses the communication buffer directly, deals with the communication receiving and sending buffer with the user program, and achieves a custom communication protocol.
2. Instruction description
