  1. FX 3U to Q CPU wireless Communication

    Hello experts, i want to connect 9 FX3U units with one  Q cpu base PLC unit over wifi, can you plz share the configuration details.
  2. FX3U to FX3U via wifi

    Good day fellow PLC ninjas! I have a question/ concern which I would love your opinions on. We have 3 FX3U PLC’s+ENET cards. Two of the 3 PLC’s move around in an EMS trolley. The other is a ‘base station’ with a GOT2000 connected via Ethernet. Base PLC IP = 192.168.1.11 HMI IP = 192.168.1.31 Carrier 1 IP = 192.168.1.61 Carrier 2 IP = 192.168.1.62 I have programmed the base PLC to use Active communication; we are using fixed buffer communication to send and receive data to/ from the Carriers. The carriers are set up as Fullpassive ‘slaves’. This part works well and the update time changes (using a counter in the base station) from 1s to 100ms (because it enters a different work station).  My issue is the following: using a network sniffer (WireShark), I pick up plenty of re-transmits and sequence number errors coming from the base PLC’s ENET card. This is troublesome and causes delays when the update time is required to be fast (100ms). I am sending and receiving 10 words of data. The wifi seems stable, and there is minimal noise in the area. The power has been turned down and the antennas used are suited well for the application. The antennas are at a similar height to minimize possible loss of signal. I have LOS (line-of-sight) to the carriers at all times; to at least one of the antennas (I am using 802.11n). Has anyone picked up issues or found settings which can be used for comms over wifi? I can easily do this using a S7-1200 Siemens PLC and have done so using 12x S7-1200 clients and 2 AP’s with 1 base PLC. I have also successfully done this using 8xFX3U client with a System Q base PLC. My suspicion is that the delay in reading and writing to/ from the BFM in the ENET card is causing this. I am not sure that if I change to a FX5U will help. The communication cards on the Mitsubishi PLC’s seem very limited. Does anyone have any technical details on the access times between the CPU and communications cards’ BFM? Help is as always, appreciated.
  3. Hi all,  I want to ask some questions regarding Ethernet Communication with FX3U PLC series. I have 2 PLCs of FX3U series (FX3U-48M and FX3U-64M) and I want to monitor its data (input and output) using ethernet communication in real time. My questions are: 1. Does FX3U PLC have ethernet port so I can connect it directly to my Laptop/PC? 2. If no, do I need to use FX3U-ENET-ADP and can it be used for 2 PLC or only 1? 3. What software do I need to use to configure the communication between PLC and FX3U-ENET-ADP? 4. Does this configuration change the existing PLC program? 5. Can i transmit the data wireless-ly using some kind of ethernet to wifi adapter and what additional hardware do i need for that?  
  4. Hi, I am replacing an AB SLC 5/03 installed in the garage in my garden with a 2nd hand 5/05 I have acquired. I am hoping to get some advice on connecting to the 5/05's Ethernet port using WiFi, allowing me to go online with it either from my desktop in the house (connected to my hub/modem) or via my laptop (connected to hub/modem via WiFi) Can this be done using inexpensive 'domestic' WiFi/Ethernet devices? The garage is just inside the house WiFi range when tested using my laptop down there. I have RsLogix 500 and RsLinx Classic. Any help/advice/comments would be much appreciated.  
  5. Hello every one. I have three FX3U plc needed to be communicate over a wireless network. I'm using serial adapter FX3U-485ADP. I got E-byte data trans reciver E-30 for wireless communication. Now need help to setup the whole thing. Previously the PLC's serial connectors were connected through a flexible bus but when the platforms are running fast there is interruption in the  communication. So we want those PLC's to be connected over wifi.  Thanks in Advance 
  6. Can anyone recommend a panel mounted WiFi access point? Ideally it will be: 24VDC supply. DIN rail mounted. Have a couple of RJ45's for connection to a LAN. WiFi Access Point to allow conenction of a tablet etc. Detachable antenna to allow fixing of antenna to cabinet exterior. Is there anything out there? Cheers.
