Program label function, when the label of the program corresponds to the label of the PLC, the ladder diagram can be uploaded and downloaded. Clearing the memory does not clear this tag either. It is mainly to limit the ladder diagram used by PLC.

~1. T250~~T255 of LX3V are 100ms timers, while T250~~T255 of LX5V are 10ms timer.

161

162

2. C200~~C234 of LX3V are double word counters, LX5V is changed to single word, and LC0~~LC255 are added as double word counters.

163

164

3. LX3V's high-speed counters C235~~C255 are no longer used. In LX5V, the high-speed counter type is configured through the configuration table, and HSC0~~HSC7 is selected as the high-speed input counter according to the channel. See the high-speed input function for details.

165

166

4. CJ instruction uses pointer P63 to jump directly to END instruction in 3V, but P63 of LX5V is a normal label.

308

309

== **Difference between high-speed counters on LX5V and LX3V** ==

310

311

LX3V updates the count value when the OUT instruction is executed, which is affected by the scan cycle.

312

313

LX5V is updated in the 100us interrupt, not affected by the scan cycle, and provides the REF instruction to refresh the current high-speed counter value immediately.

314

315

LX5V single-phase high-speed counter supports filtering function, configurable 0~~17us.

316

317

LX5V high-speed input counter will update the input frequency in the special soft element (SD) every 100us.

340

~1. LX3V has multiple high-speed pulse devices that are shared by multiple axes, while LX5V is separated. Therefore, when converting the program, this type of special address needs to be assigned to all axes together. For example, D8148 of 3V is the acceleration and deceleration time of 4 axes Y0~~Y3, then in LX5V, Y0 acceleration time SD902, deceleration time SD962 and other axis acceleration and deceleration time need to be set to the value of D8148.

**~1. Communication parameter configuration**

469

470

There is a difference in the serial port parameter settings, mainly in the start bit of STX and ETX of the custom protocol. 3V is B8 B9 and 5V is B10 B11. The main reason is that 5V increases the baud rate of 921600.

471

472

Although 5V does not have 3V HMI monitoring protocol. But the current HMI has matched the 5V Wecon Modbus slave protocol. The Wecon Modbus slave protocol is modified based on ModbusRTU slave, Compatible with all ModbusRTU slave content.

504

505

**3. Differences in special devices**

506

507

3V only supports setting the serial port parameters in the first cycle of the scan cycle. The mode of the first cycle setting can be switched only by modifying the corresponding soft element setting according to the special soft element comparison table.

540

541

Modify serial communication parameters during RUN. For example, use PROTOCOL instruction to modify the protocol during run. The corresponding instruction description can also find the method of setting without instruction. For details, please refer to the relevant instructions of the instruction. Commands are PROTOCOL (set serial port protocol), PROTPARA (set serial port parameters), STATION (set station number)
