3.USB-SC09 is a domestic download line, can be used for FX series PLC and A series PLC, the computer side for the USB interface, easy to use
4.SC09 is mainly for the old computer (comes with RS232C 9-pin interface), the computer side for the RS232 interface, and now the computer needs to use a USB to RS232
Of the adapter can be connected to use, such as USB-RS232 2.0
Fourth, FX2N PLC with FX3U replacement, the original module needs to be replaced?
1.FX2N PLC with FX3U replacement, the original function expansion board (communication with the BD board and special adapter such as FX2N-485BD, FX2NC-232ADP) need to replace the FX3U series corresponding function expansion board;
2. Expansion devices (input and output modules, special function modules such as FX2N-16EX, FX2N-2AD) are not replaced and can be used directly.
5, FX0N-65EC expansion cable is not necessary to be equipped with a FX2N-CNV-BC adapter can be connected to use ah?
FX0N-65EC When FX2N-32ER / ET, FX2N-48ER / ET is connected, FX2N-CNV-BC
6, FX2N series PLC model suffix ES / UL with -001 What is the difference?
1. Suffix for the ES / UL for the European version of the model, -001 for the Chinese version.
2.-ES / UL series input mode can be through the S / S terminal, and select the source type, leakage type input mode. And -001 series input method is fixed for the leakage type input.
7, FX0N-65EC is not necessary to add a FX2N-CNV-BC adapter can be connected to use ah?
FX0N-65EC FX2N-CNV-BC is not required when connecting FX2N-32ER / T.FX2N-48ER / T; other modules need to be added
8, FX1S, FX1N, FX2N, FX3G, FX3GA, FX3U (C) body comes with high-speed pulse output point can control the number of shaft?
1.FX1S, FX1N can control the independent 2-axis, the maximum output 100KHZ pulse train
2.FX1NC can control the independent 2-axis, maximum output 10KHZ pulse train
3.FX2N can control the independent 2-axis, the maximum output 20KHZ pulse train
4.FX3G, FX3GA 14/24 points can control the independent 2-axis, 40/60 point maximum output 100KHZ pulse train
5.FX3U, FX3UC can control the independent 3-axis, the maximum output 100KHZ pulse train
9, FX1N PLC can expand the connection FX2N input and output modules, analog modules, positioning modules, etc.?
FX1N PLC can expand the expansion module connected to FX2N. Such as FX2N-16EX, FX2N-16EYR, FX2N-4AD, FX2N-10GM, FX2N-20GM, etc.
10, FX series PLC in operation, the power LED lights off or flash how to do?
First, remove the wiring of the [24 +] (working power) terminal on the PLC to confirm that it is back to normal.
1: If the return to normal, it may be due to the load short or too large load current caused by the power supply capacity overload to start the protection function.
2: If you can not return to normal, please contact the professional and technical personnel for maintenance.
11, FX3U-ENET-ADP and FX3U-ENET-L What is the difference, whether they can replace each other?
FX3U-ENET-L is the Ethernet module, FX3U-ENET-ADP is the Ethernet port adapter; -L powerful, can replace the ADP; the other can replace, you have to refer to the function used to meet, to judge The
1: ENET-ADP and ENET-L have MELSOFT connection function, the function is through the Ethernet port and the man-machine interface, such as Mitsubishi, Wei Lun touch screen
2: ENET-ADP and ENET-L have MC protocol (ie, Mitsubishi PLC special protocol), the role of the role of the host IPC and other MC protocol to read, write and control PLC
3: ENET-L module has a large number of buffers, with the cache send and receive function (1024 words / times), can be used as a master station and third-party equipment such as instrumentation, etc., ENET-ADP is only a communication expansion port, without this function
12, FX3U-1PG can 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 universal
2.FX3U-1PG can only be used in the FX3U PLC host above, after the replacement to determine whether the host FX3U PLC
Thirteen, Mitsubishi FX3G series PLC how and bar code scanning gun communication? How do I read barcodes in Mitsubishi 3G PLC?
With the RS command on it, you have to read the scanner bar code must know that his communication protocol is dedicated or MODBUS agreement, and then to know the bar code data storage area address and data type and size, and then easy to use RS instructions To read the site of the bar code storage area address data, if it is two words of the feedback data as long as the two words of the class capacity to show just fine.
Four, ready to try to make a control system, control a stepper motor, four cylinders, there are four close to the switch input, choose what model of the PLC cost-effective?
This simple system what models can be, FX2N FX1S FX3U you can choose, mainly the transistor output just fine.
Fifteen, how to control the servo motor with PLC?
The distance per revolution is calculated from the resolution of the encoder and then controlled by pulse

800-4000
Seventeen, PLC positioning module must be used with the servo?
Must be equipped with servo, according to the parameter positioning data to the servo amplifier output instructions
Nineteen, choose Mitsubishi FX3GA series PLC and Mitsubishi FX3U series PLC which is good?
According to the specific use to choose, the software is the same
Twenty, Mitsubishi’s several series of PLC in the programming What is the difference?
Basically no difference, FX2NC and FX3U most of the instructions common
