  1. Built-in Ethernet vs QJ71E71 Module

    valsidalv posted a topic in Mitsubishi

    This is my company's first time using a Mitsubishi PLC and our partners/clients advised us against using the built-in Ethernet port on the Q03UDE CPU, saying that we should instead use a standalone QJ71E71 Ethernet module. The QJ71E71 costs 1.5x the CPU module so there are significant savings in using the built-in Ethernet. They cited reliability issues but can anyone here back up their claim? We use our PLCs as simple I/O blocks - a PC runs a program which communicates with the PLC and tells it what outputs to fire. There is no actual ladder logic on the PLC. The PC connects directly to the PLC. I wrote a small C# utility that blasts the QX40 and QY80 input/output cards on my stack with random values and reads them back to ensure correct data transfer. The QJ71E71 Ethernet module averages 10 ms for a read or write operation and the Q03UDE averages 3 or 4 ms (much quicker!). So, does anyone have a reason to use the QJ71E71 port instead of the CPU? Thanks

  4. Hello, I have an annoying problem with communication between Siemens S7 PLC and HMI panel. Here it how it looks like: I am using Siemens S7-315 with 343 Lean ethernet port. This port is used to communication with HMI terminal. Communication is realized through S7-TCP communication protocol. When I was testing the communication in the office everything worked fine and nothing wrong happened. The problem occururs only on the installation. After turning the PLC and HMI on everyting works fine, data is transferred correctly and variables are displyed on HMI. After a few hours the communication is suddenly lost. This is a direct connection between PLC and HMI and there are no other devices in this network. So it is not possible that suddenly there is an address confilct. I made a wireshark analysis (I connected a notebook and hub into the network) and I found out that when the communication is lost HMI terminal is trying to get data from the PLC but it is not responding. It looks like PLC ethernet port is broken. You cannot ping PLC from notebook and HMI. On the other hand you can exchange pings between HMI and notebook. The communication is back again only if you'll restart the PLC. The strangest thing is that I did not have any problem with the communication when I was testing it in the office. The configuration and project of PLC and HMI is excactly the same. The only difference is that on the installation PLC is realizing also a communication throguh Profibus and MPI. I've tried to use different ethernet cables (crossed, non-crossed) but in all cases the situation is the same. Do you know waht can be the cause of such behavoiur? Maybe someone had a similar situaion? In the attachment I send a screenshot from Wireshark which shows the moment when the communication breaks.

  6. Control G120C via Profibus

    Bryll posted a topic in Siemens

    I'm trying to control the speed of a G120C via profibus, but it will trip out when any changes are done to the speed value. The unit was commissioned by another guy, and he doesn't have a clue where to look. We can start and stop the unit, but it will stop at any attempt to change the speed. I was told to look for a parameter allowing it to be controlled remotely, but wich one is it ? As usual when it comes to Siemens, the manual sucks. I'm using a function block for controlling the drives (13), and the older 12 is responding correctly to any change. Anyone here that has a clue what parameter to change ?
  7. I have a 2 axis control that runs a pair of identical servo drives. as of late I have been getting reports from the operators that the two motors, while jogging forward will suddenly run in the reverse direction at a high rate of speed. There is not a reversing function on these axes in an way. I am suspecting there may be a problem in the analog output of the module causing an inversion of the signal which in turn causes the motors to run in reverse. This setup has been in operation without any instance of this happening for around 5yrs before any issue with out of control runs. All cabling has been checked and is properly shielded and grounded.
  8. Hi I have a scenario where I need to setup communication between a Mitsubishi L-series PLC to Schneider Modicon M580. I need to use the onboard ethernet port of the L-series PLC. The protocol I need to use, is Ethernet IP. (socket communication). Can someone please assist?

  10. Hi Good Day, I need a suggestion, I have an omron encoder, encoder counter meter (K3NC-NB1A) and communication card RS-232C 25pins (K31-FLK1). My question is, what is the best omron software to read and manipulate the data from the encoder (I have CX-one software but I only use CX-programmer). I want to capture the encoder pulse and convert to velocity, acceleration, deceleration and also energy absorbtion. I have to use mathematical formula such as two times differentiation. I also need to show grapf and display final result that is energy absorbtion reading. Or is it much simple if I use VB / labview / java software? Thank you in advance
  11. I'm just starting to learn Ladder Logic Programming. I'm using Allen Bradley RSLogix 5000. I've been tasked with developing a 'Simple' Coffee Machine which operates like so: Toggle Push Button to StartDrop Cup (for 10 seconds)Feed Hot Water (for 10 seconds)If required, Add Milk (for 10 seconds)If required, Add Sugar (for 10 seconds)Procedure Complete - Illuminate Complete Light (for 10 seconds)I have implemented everything except the OPTIONAL add Milk & OPTIONAL add Sugar. Options are: To have a Coffee without either Milk or Sugar.Or have a Coffee with Milk and Not Sugar.Or have a Coffee with Sugar & Not Milk.Or have a Coffee with BOTH Sugar & Milk. I'm considering using Toggle Buttons to select / jump to a Subroutine (choosing the required ingredient make-up). But I'm wondering if there is another way to sequentially go through the procedure? Thanks. http://stackoverflow.com/questions/26930902/ladder-logic-simple-coffee-machine-optional-add-milk-add-sugar?noredirect=1#comment42839041_26930902
  12. Hi all, While upgrading HMI from PanelBuilder32 to FactoryTalk View I encounter a problem using I/O to interface with a PanelView Plus. The communication is defined in RSLogix 5 program as Rack 3 group 2 Size 3/4, range 32-37. PLC communication with the panel is not changed, but buttons in old PanelView using I:34 and I:35 work, in the new PV+ they don't, all bits remain zero. Block transfers Read and Write are all sending data to rack 3 group 2 module 0. While testing I noticed O:32 is used as status bits by the Block Transfers - maybe inputs I:34 and I:35 are also used for somethings similar by a new PanelView Plus? Thanks!

    AlexCyril posted a topic in CX-Programmer

    Hello guys, actually I am new to this Omron PLC. but i have small project to transmit a command to the GSM modem via the RS232 port so it can trigger the modem to send text msg. Can you show me the steps/guide/sample program to accomplish this program coding? I already read some topic in this forum regarding to this PLC RS232 port but still cant get the ideas when to create the ladder program. PLC Type : CJ1H (CPU65H) - RS232 port First input to trigger the GSM send text msg: AT+CMGS="+YOUR HP NUMBER" Second input to trigger GSM send text msg: YOUR TEXT MSG CONTAINS (Ctrl+z to send) Many Thanks, AlexB
  14. Hi. I have a ST-Lite Ethernet base (STL-ETH1) with 1 16 bit digital in card, 3 digital out cards, 2 analog in and 2 analog out cards. I have a Q03UDE CPU (Q PLC) with 1 16bit digital in and 1 digital out card. Now I like to setup the remote I/O (STL-ETH1) mapped to the Q PLC via the ethernet port on the CPU. Is it possible not to use Modbus at all. I don't want to go and buy a Modbus Ethernet card now. Have someone done this before?
  15. Hello all, I am trying to download a new program to a AB 1746-BAS SLC 500 BASIC board via RS-232 connection through a Windows 98 laptop running Hyperterminal. While the BASIC board is connected I verify connection by waiting for the board to print out its information in the Hyperterminal program and then enter "CLEAR", "NEW" and finally, "LIST" in Hyperterminal to wipe any program from the board and verify the board is clean respectively. Then I load the new program via a .TXT file using the "Send Text File" option within the Hyperterminal program. After the program has finished loading I than type "LIST" to verify it has copied over correctly. I than switch the SLC over to "Program Mode" via the key. After doing so I type "RAM" to select the program i just uploaded to the BASIC board and then type "PROG" in the Hyperterminal program. I than receive the "Programming Sequence Failure". If anyone has any advice as to what I am doing wrong it would be greatly appreciated. Below is a list of everything I have set and researched. Thank you in advance, James -Laptop: Windows 98, Hyperterminal -BASIC board (programming): JW1 pin: 1-2 3-4 JW2 pin: 1-2 3-4 JW3 pin: 1-3 2-4 JW4 pin: 5-6 3-4 -RS-232 9-pin connector: Pin 2 connected to Tx Pin 3 connected to RX Pin 5 connected to ground Pins (4/6) crossed DSR/DTR Pins (7/8) crossed RTS/CTS -Hypterminal: Direct Com1 bits per second: 1200 parity: none stop bits: 1 Flow control: Xon/Xoff Settings/properties: -> Emulation VT100 -> ASCII line/character delay: 30 milliseconds check box: Append line check box: Wrap lines... -Manuals: 1746-rm001 1746-pm001
  16. I have 4 Allen Bradley PLCs which are 3 SLCs and 1 CLX This PLCs need to send data to Yokogawa Centum VP DCS. Instead of having and individual Modbus link to DCS, I'm planning to link all 4 PLCs by using Ethernet/IP and plan to buy 1 extra mini PLC which is Micrologix 1400 to become an interface PLC between the 4 PLCs and the DCS. Since the Micrologix 1400 has embedded with an Ethernet port (Ethernet/IP) and Rs485 port for Modbus RTU, the Micrologix 1400 interface PLC will communicate with DCS using Modbus RTU Protocol. Meaning to say, the 4 PLCS will send data to the Yokogawa DCS via interface PLC. The Interface PLC will become translator to translate from Ethernet/IP language to Modbus RTU language. My question to Expert: 1. Is this setup can works? 2. How to send data inter-PLC by using Ethernet /ip ? Is it just need to grab the tagname or there is an address for that? 3.Is Micrologix is capable to communicate with 4 PLCs using Ethernet/IP? Or just only 1 PLC? See the attached photo. Thanks. -Nizam-
  17. I have a project I am starting and I have to be able to wind a small diameter wire onto a 1/16" shaft, .5 to 1.5" wide and 13 layers at a max speed of 2,000 rpm. Is there anyone who has done something like this and have some sample code? I am gearing 2 Kinetix 350 drives with 2 AB servos.I have a separate tension unit that I have to communicate via RS485. Not to concerned about that. As the coil winds the traverse will move the wire back and forth.

  20. Inverters on Profibus

    Bryll posted a topic in Siemens

    Hello, Tried to get some good and clear answers at the Siemens forum, decided to try here aswell. I have a setup with 12 G120C inverters and three gas burner units on a profibus line. If I unplug any of the devices will I of course get an error from the loaded OB. But, now and then can I lose the connection to two or more of the inverters without any notification. It seems that the communication is up and running, but the don't respond to any commands. The normally green LED on the inverters switch over to flashing red when they stop to respond. They will also show fault code 1910. I am using standard telegram 20, this is also set in the inverters parameter lists. Another funny thing is that the fault bit in the status word is always set. Even when the inverters don't hav any faults or alarms. ZSW looks like this (with or without response from the inverter): Bit 0 = 1 (Ready for switching on) Bit 1 = 1 (Ready for operation) Bit 2 = 0 (Running) Bit 3 = 1 (Fault) On all the time, even when there is no faults in the inverter Bit 4 = 0 (No coast down active) Bit 5 = 1 (No fast stop active) Bit 6 = 1 (Switching on inhibited active) Bit 7 = 0 (Alarm present) Bit 8 = 1 (Speed setpoint - actual value deviation within tolerance) Bit 9 = 0 (Control requested) Bit A = 0 (f or n comparison value reached) Bit B = 0 (I, M or P limit not reached) Bit C = 1 (Reserved) Bit D = 1 (No motor overtemperature alarm) Bit E = 0 (Direction of motor rotation) Bit F = 0 (Display CDS) Anything I might have missed or done wrong ?

  22. Hi everyone, my client has a Direct Communication network consisting of Allen bradley 1772-SD2 (PLC2) and 1771-DCM modules. I need to upgrade one of the adapter node from 1771-DCM to newer hardware. My client is insists to KEEP the 1772-SD2 scanner as it is. So essentially I need a recent hardware to replace 1771-DCM and work with 1772-SD2. Do I have any option to upgrading this node with recent generation solutions?
