161 ~1. T250~~T255 of LX3V are 100ms timers, while T250~~T255 of LX5V are 10ms timer.
162
163 2. C200~~C234 of LX3V are double word counters, LX5V is changed to single word, and LC0~~LC255 are added as double word counters.
164
165 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.
166
167 4. CJ instruction uses pointer P63 to jump directly to END instruction in 3V, but P63 of LX5V is a normal label.
168
169 5. Pointer I is cancelled in LX5V, please check the programming mode for details.

197
198 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)
199

236 LX5V does not support CJ P63 to jump directly to the END instruction.
237
238 LX5V does not support CJ instructions to jump into subroutines and interrupts.

241
242 There is no need to connect the contact before the DI instruction of LX3V.
243

261
262 CPVAL is used to configure communication BD boards in 3V. LX5V does not currently support it.
263
264 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).

287
288 [[image:1652689864332-317.png]]
289
290 Through special registers, configure the functions such as frequency multiplication and counting direction.
291
292 Use the OUT instruction to start the high-speed counter counting.

294 [[image:1652690126303-800.png]]

298 According to channel, select the HSC register to use:
299

302 Configure the high-speed counter mode through the host computer configuration table：
303
304 [[image:1652692281566-353.png]]
305
306 Use the OUT instruction to start the high-speed counter counting.
307
308 [[image:1652692388207-617.png]]
309
310 == **Difference between high-speed counters on LX5V and LX3V** ==
311
312 LX3V updates the count value when the OUT instruction is executed, which is affected by the scan cycle.
313
314 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.
315
316 LX5V single-phase high-speed counter supports filtering function, configurable 0~~17us.
317
318 LX5V high-speed input counter will update the input frequency in the special soft element (SD) every 100us.

338
339 **Special device change**
340
341 ~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.

469 **~1. Communication parameter configuration**
470
471 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.
472
473 **2. Differences in protocol settings**
474
475 3V settings:
476
477 (% class="table-bordered" %)
478 |=(% scope="row" %)**protocol**|=**D8126 value setting**
479 |=RS instruction (custom protocol)|00H
480 |=HMI monitoring protocol (PLC protocol)|01H
481 |=MODBUS-RTU slave|02H
482 |=MODBUS-ASCII slave|03H
483 |=N:N network communication protocol slave|04H
484 |=RS instruction (custom protocol)|10H
485 |=MODBUS-RTU master station|20H
486 |=MODBUS-ASCII master station|30H
487 |=N:N network communication protocol master station|40H
488
489 5V settings:
490
491 (% class="table-bordered" %)
492 |=(% scope="row" %)**SD2592 value setting**|=**Protocol**
493 |=0 H|Wecon Modbus slave
494 |=2 H|ModbusRTU slave
495 |=3 H|ModbusASCII slave
496 |=10 H|User-defined protocol
497 |=20 H|ModbusRTU master station
498 |=30 H|(((
499 ModbusASCII master
500
501
502 )))
503
504 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.
505
506 **3. Differences in special devices**
507
508 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.
509
510 **4. Slave address difference**
511
512 5V address:

540 **5. LX5V added functions**
541
542 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)
