Second, FX3U replace FX2N, and FX3UC replace FX2NC, what adjustments and changes need to be done?
1. The FX3U(C) series corresponds to the FX2N(C) series. Their dimensions are the same. No need to change the cabinet installation.
2. FX3U (C) series input / output terminal block size and position the same, replace the PLC without stitches, you can directly remove the old machine terminal to the new machine
3. The wiring of FX3UC and FX2NC is exactly the same; FX3U will have one more input signal type than SFX FX2N to select the S/S terminal, which needs to be shorted to 24V, and the previous position of FX2N is empty.
Third, what are the differences between the FX series PLC download lines and their differences?
FX series download line has FX-USB-AW (original), USB-SC09-FX, USB-SC09, SC09
1.FX-USB-AW is Mitsubishi original FX dedicated download line, the computer side is USB interface, reliable and convenient to use
2. USB-SC09-FX is a domestic download line imitating Mitsubishi FX-USB-AW, the computer side is a USB interface, easy to use
3. USB-SC09 is a domestic download line, can be used for FX series PLC and A series PLC, the computer side is a USB interface, easy to use
4.SC09 is mainly for the old computer (RS232C 9-pin interface), the computer side is RS232 interface, now the computer needs a USB to RS232
The transfer interface can be used for connection, such as USB-RS232 2.0
Fourth, FX2N PLC replaced with FX3U, the original module needs to be replaced?
1. After FX2N PLC is replaced with FX3U, the original function expansion board (BD board for communication and special adapters such as FX2N-485BD, FX2NC-232ADP) needs to be replaced with the corresponding function expansion board of FX3U series;
2. The expansion equipment (input and output modules, special function modules such as FX2N-16EX, FX2N-2AD) can be used without being replaced.
Five, FX0N-65EC expansion cable is not must be equipped with a FX2N-CNV-BC adapter can be connected to use ah?
FX0N-65EC does not need to add FX2N-CNV-BC when connecting FX2N-32ER/ET, FX2N-48ER/ET
Six, FX2N series PLC model suffixES/UL What is the difference with-001?
1. The suffix ES/UL is the European model, and the -001 is the Chinese version.
2.-ES/UL series input mode can be selected through the S/S terminal, and source and sink input methods can be selected. The -001 series input is fixed as a sink input.
Seven, FX0N-65EC Is it necessary to add a FX2N-CNV-BC adapter to connect to use ah?
FX0N-65EC does not require FX2N-CNV-BC when connecting to FX2N-32ER/T.FX2N-48ER/T; other modules need to be added
VIII, FX1S, FX1N, FX2N, FX3G, FX3GA, FX3U (C) body with high-speed pulse output point can control how many axes?
1.FX1S, FX1N can control independent 2-axis, maximum output 100KHZ pulse train
2.FX1NC can control independent 2-axis, maximum output 10KHZ pulse train
3.FX2N can control independent 2-axis, maximum output 20KHZ pulse train
4.FX3G, FX3GA 14/24 points can control independent 2-axis, 40/60-point maximum output 100KHZ pulse train
5.FX3U and FX3UC can control independent 3-axis, maximum output 100KHZ pulse train
Ninth, can FX1N's PLC expand the FX2N's input and output modules, analog modules, and positioning modules?
FX1N's PLC can fully expand the expansion module connected to FX2N. Such as FX2N-16EX, FX2N-16EYR, FX2N-4AD, FX2N-10GM, FX2N-20GM, etc.
Ten, FX series PLC in operation, the power LED lights off or blinking how to do?
First, remove the wiring of the [24+] (operating power supply) terminal on the PLC and check whether it is normal.
1: If it returns to normal, it may be because the load is short-circuited or the load current is too large and the operating power supply capacity is overloaded, thereby starting the protection function.
2: If you can not return to normal, please contact professional and technical personnel for maintenance.
What is the difference between FX3U-ENET-ADP and FX3U-ENET-L?
FX3U-ENET-L is an Ethernet module, FX3U-ENET-ADP is an Ethernet adapter; -L is powerful and can be used as an alternative to ADP. Conversely, whether or not it can be replaced depends on whether or not the used function is satisfied. .
1: Both ENET-ADP and ENET-L have MELSOFT connection function. The function is to connect with the man-machine interface through the Ethernet port, such as Mitsubishi, Wei-lun touch screen.
2: Both ENET-ADP and ENET-L have the MC protocol (ie, the Mitsubishi PLC protocol). This function is used by the upper IPC to read, write, and control the PLC using the MC protocol.
3: ENET-L module has a large number of buffers, buffer send and receive function (1024 words / time), can be used as a master station and third-party devices such as instrumentation and other communications, ENET-ADP is just a communication expansion port, there is no such function
12. Can FX3U-1PG replace FX-1PG-E?
1.FX3U-1PG is an upgraded version of FX2N-1PG/FX-1PG-E; performance boost pulse output up to 200KHZ, their program can be used universally
2.FX3U-1PG can only be used on the FX3U PLC host, after the replacement determines whether the host is FX3U PLC
13. How does Mitsubishi FX3G Series PLC communicate with barcode scanners? How to read the barcode in Mitsubishi 3G PLC?
RS instruction is all right. You have to read the bar code of the scanner and you must know his communication protocol. It is dedicated or MODBUS protocol. Then you need to know the data storage area address, data type and size of the bar code, and then use the RS command. To read the data of the address of the bar code storage area of ​​this site, if it is two words, the data to be fed back only needs to display the categories of these two words.
Fourteen, ready to try to do a control system, control a stepper motor, four cylinders, there are four proximity switch input, what type of PLC cost?
This type of simple system can be any model, FX2N FX1S FX3U you can choose, mainly transistor output just fine.
15. How to use PLC to control servo motor?
Calculate the distance per revolution based on the resolution of the encoder and then use pulse control
16. What is the corresponding parameter of the 4-20mA current output of the 4ad module of Mitsubishi FX3U series PLC?
800-4000
Seventeen, PLC positioning module must use servo?
Must cooperate with servo, output command to servo amplifier according to parameter positioning data
Nineteenth, choose Mitsubishi FX3GA series PLC and Mitsubishi FX3U series PLC which is good?
According to the specific purpose to choose, the software is the same
