156
157 ~1. T250~~T255 of LX3V are 100ms timers, while T250~~T255 of LX5V are 10ms timer.
158
159 2. C200~~C234 of LX3V are double word counters, LX5V is changed to single word, and LC0~~LC255 are added as double word counters.
160
161 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.
162
163 4. CJ instruction uses pointer P63 to jump directly to END instruction in 3V, but P63 of LX5V is a normal label.
164

185
186 **LX3V interrupt**
187
188 The interrupt program is under FEND and returns with IRET. The meaning of the specific interrupt is distinguished by the pointer I number.(Refer to EI/DI instruction in 3V)
189
190 The 1ms interrupt program of LX3V is as follows:

225
226 LX5V does not support CJ P63 to jump directly to the END instruction.
227
228 LX5V does not support CJ instructions to jump into subroutines and interrupts.
229
230 **DI, EI instructions**
231
232 There is no need to connect the contact before the DI instruction of LX3V.
233
234 [[image:1652687225743-267.png]]
235
236 The contact must be connected before the DI instruction of LX5V.

251
252 CPVAL is used to configure communication BD boards in 3V. LX5V does not currently support it.
253
254 CPVAL is used to switch electronic cam table in LX3V. LX5V uses ECAMCUT instruction(Refer to Chapter 9.1 of LX5V Programming Manual for details).

279
280 Through special registers, configure the functions such as frequency multiplication and counting direction.
281
282 Use the OUT instruction to start the high-speed counter counting.

288 According to channel, select the HSC register to use:
289

292 Configure the high-speed counter mode through the host computer configuration table：
293
294 [[image:1652692281566-353.png]]
295
296 Use the OUT instruction to start the high-speed counter counting.

298 [[image:1652692388207-617.png]]
299
300 == **6.3 Difference between high-speed counters on LX5V and LX3V** ==
301
302 LX3V updates the count value when the OUT instruction is executed, which is affected by the scan cycle.
303
304
305 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.
306
307 LX5V single-phase high-speed counter supports filtering function, configurable 0~~17us.
308
309 LX5V high-speed input counter will update the input frequency in the special soft element (SD) every 100us.

329
330 **Special device change**
331
332 ~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.

462 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.

495 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.

497 **3. Differences in special devices**
498
499 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.

531 **5. LX5V added functions**
532
533 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)
