It is almost impossible that 3 cards have malfunctioning current part of analog output. I presume that you changed the wiring for current mode comparing to voltage mode, and forced M8114 to zero?.
-
I already wrote you reply on PLCTalk (https://www.plctalk.net/threads/problem-with-analog-output-fx1n-1da-bd.139641/). Most likely there it is not up to PLC or PLC card. It can be either bug in program or problem with sensors. Why don't you post program so we can analyze it?

FX3U with GX Works2 or GX Developer - no ip change possible
Goran Vuckovic replied to pjw's topic in Mitsubishi
It may be also directly programmed in PLC application. -
First is to notice that, the machine has to have much more than 10 years, because of A1S. Second, is from my experience - when I had similar problems in past it was almost always grounding or/and sometimes overvoltage. My advice is put IT transformer with slightly reduced secondary voltage in front of 24VDC power supply, change PLC power supply from 230VAC to 24VDC, provide separate paths to PLCs LG and FG (Logic Ground and Fault Ground).

Have you solved the problem? If yes, what was solution?
-
I would try to check Screen Switching. It is possible that that register is somehow overwritten. For example you have selected D11 as Base Screen, but you have cleared that value at PLC start, or you have registered label wrongly at D10 as double etc.

Modifying Symbols Or Importing into GTdesigner3
Goran Vuckovic replied to jdcontrolsltd's topic in Mitsubishi
You can import it as Part in Project Docking Windows (usually BMP, PNG or JPG) and the you can click on imported image select and you can specify transparent color.- 1 reply

IVRD is used for reading inverters parameters from Mitsubishi VFDs. On other side, Mitsubishi PLC clones, usually do not support FROM and TO, and usually you need to use RD3A command.

Hubs are Layer 1, switches are Layer 2 and there are Layer 3 switches/routers. I have connected many Q PLCs in my life, and if you connect them directly you need crossover except if your PC has Auto MDI-X, and it will have if it is Gigabit port. If you have problems connecting it with hub, just buy simple switch instead of hub and try it. Today switches are so cheap that it costs you or your company more to write all this posts than to try it. For example Tenda SG105, unmanaged , 5-port, Gigabit switch costs 10$.

I didn't understand your previous question, but I will try to explain. Q port doesn't support Auto MDI-X so you will need crossover cable to connect PC to PLC. Switches support Auto MDI-X, so you can use either straigth or crossover cable. HUBs most likely do not support Auto MDI-X, so you will likely need to have crossover cable from HUB to PLC. Remember that idea is to connect PLC Transmit to PC Receive and PC Transmit to PLC Receive.
-
If you are connecting directly to Q port, than you need crossover, if you are connecting through switch than straigth cable is ok. It could be that with hub you need crossover cable.

Tight VNC HMI connection getting automatically disconnected
Goran Vuckovic replied to Ramkumar's topic in Mitsubishi
Is VNC Server Function License installed? What is value of "Operating priority guaranteed time"? -
There is small chance that multimeter or most measuring devices will detect changes with duration of 10ms.

Pseudoposition control with FR A800 E Series + Beijer XP 340 PLC + Incremental encoder
Goran Vuckovic replied to pedrovg's topic in Mitsubishi
I think that easiest method would be by using PLC inside function of A800, and adding one inductive proximity sensor for 0 degrees. After that everything would be more or less simple math. -
Mitsubishi F-A800 E Series not controlling via Modbus
Goran Vuckovic replied to pedrovg's topic in Mitsubishi
Before start try to put parameters below to listed values: 77 - 2 (Parameter writing is enabled in any operation mode regardless of the operation status.) 550 - 5 Be sure that you are in NET mode. Then you can try command: FF0600090001 Also try FF0600080001 because I'm not certain is it +1 Modbus addressing. -
Mitsubishi F-A800 E Series not controlling via Modbus
Goran Vuckovic replied to pedrovg's topic in Mitsubishi
For command 06 - Modbus Exception code 02 : "The data address received in the query is not an allowable address for the slave. More specifically, the combination of reference number and transfer length is invalid. For a controller with 100 registers, a request with offset 96 and length 4 would succeed, a request with offset 96 and length 5 will generate exception 02." For command 10 - Modbus Exception code 03: "A value contained in the query data field is not an allowable value for the slave. This indicates a fault in the structure of remainder of a complex request, such as that the implied length is incorrect. It specifically does NOT mean that a data item submitted for storage in a register has a value outside the expectation of the application program, since the MODBUS protocol is unaware of the significance of any particular value of any particular register." It is 20h o'clock at my country, and I am going on dinner with my wife. We will continue tomorrow, and I will help you. -

After that try this: FF06000A0001 000A is 40009 -

Mitsubishi F-A800 E Series not controlling via Modbus
Goran Vuckovic replied to pedrovg's topic in Mitsubishi
Yes, I have experience with A800 and Modbus. Why don't you send me the response from Etherway, and we could see a lot from that. -

Control FR A800-E over Modbus with Beijer PLC
Goran Vuckovic replied to pedrovg's topic in Mitsubishi
It has Modbus, CC-Link (all versions, Serial&Ethernet, IE, TSN), Profinet, Ethernet/IP, Mitsubishi Inverter Protocol, Profibus, Devicenet, CANopen, Controlnet, FL-Net, Lonworks, BACnet, SSCNet, EtherCAT. Some of them are standard, and some of them are as option. So Modbus is far from only protocol. About Modbus implementation, I am not 100% sure if it has Modbus FC23 Read/Write, but other than that I don't see how it is lame. There is one thing with Mitsubishi VFDs and that is that Parameters Number are practically always the same in last cca 35 years, on every model Mitsubishi is adding parameters not changing them, so you don't need to learn it again, but it tends to be confusing for new guys. As remedy there is FR Configurator Software that helps a lot. -
Mitsubishi F-A800 E Series not controlling via Modbus
Goran Vuckovic replied to pedrovg's topic in Mitsubishi
I suggest that you to download Omron EtherWay app (it is free of charge) and test communication and post response. Also on myMitsubishi site, there is example for GOT HMI and E800, with Modbus TCP/IP and it is very similar VFD (in communication sense). The example is called "FR_E800_EPA_ModbusTCP_from_GOT2000_and_NZ2FT_MT_Slice_IO". -
Control FR A800-E over Modbus with Beijer PLC
Goran Vuckovic replied to pedrovg's topic in Mitsubishi
It look like you have not used it. From my experience, if you want job done it is the best ever VFD I have used (and I have used many different VFDs from various producers). Just to mention that PLC function inside it has, that is very powerful. I have used it for several application where servo was originally intended . Only drawback is the price. Maybe my language barrier is making problem to me, but I don't understand what are the problems you noted with frequency/speed reference. You can program it to have three control modes that are selectable either from VFD or through communication, and every mode can work in different way. I think that it is benefit not drawback. -
MELSEC-L PID Control (Function block difference / limit)
Goran Vuckovic replied to Neverov's topic in Mitsubishi
I have made my own PID for Q series, and I have used it for more than 50 PIDs simultaneously. The processes were not to fast (mostly 100ms sampling). If you make your ow function, at the end it will all depend of CPU processing power. With L26 it should be easy to do it, with L02 I don't believe it is possible, with L06 depending of memory capacity other already used for other function (very likely you can do it).- 1 reply
