Hello, I'm new to this forum and PLC world in general (especially to Mistubishi PLCs). I have a task in which I need to synchronize servomotor with another motor that runs conveyer (servomotor needs to stamp a label on a foil on a conveyer), in GX Works3. Servo motor is run by Simple Motion module. I need general tips on how to make pulses from encoder into something useful that can be used to send data to Simple Motion module. I need high speed counter to count pulses (never actually did this, I got this from manuals), how would I, for example, get speed out of it? Number n pulses, divide it with time it took to get to n pulses? How would I make Simple Motion to make servomotor on his Axis #1 to rotate at same speed?    

Hi! I have my 1756 IF8 wired in high speed differential mode but i can't configure the RTS smaller than 11 ms. What I understand it should be possible to set as low as 5 ms if module filter setting is 1000 Hz. Is there anything else that i have to do?

Hi 1- How can I identify a disable x20 module (in physical view) cyclically ? I am looking for a funation block who can do that because I want to use the 'Module Ok' status of x20 module to check if their presence. Problem is 'module Ok' status is the same for module missing or disable. 2- Could I disable a module using fonction block? (FYI I already know the right click in physical view). Thanks  

Hi guys, been using this site for a long time, it has come in handy alot. However I have recently taken on my first servo project, heres an overview of the project We have a filling machine that has a separate dosing system to the filler head. It used to keep the dosing in time by adjusting a 0-10v signal to an inverter to make sure that a flag makes a sensor in a set window. I have installed an encoder on the filling head and an mpl servo to the dosing. I have then used an MAPC instruction to follow the encoder, the cam is 0-360 and it follows a straight linear line. I have installed of this as a temporary set up on one of the filling machines (we have 2) and it is working perfectly. I have now installed this on the second machine as a permanent set up with a panelview plus 7, L71 cpu. However it is giving a very strange problem on first power up, the encoder is giving the exact same position as before it was powered down. however as soon as the MAPC executes the servo axis  faults, giving an overspeed fault. the servo doesnt even look like its attempting to move (however it is through a 10-1 gearbox). if i then home the encoder it then runs absolutely perfectly until it is powered down again. I am beginning to think it may be to do with the master lock and cam lock position, as the cycle stop position of the two machines are different. however I just cant seem to get my head around i the difference between them.   Hopefully that makes sense any help would be greatly appreciated Thanks Rhys   c1_dosing.ACD

Hi. I have Q12HCPU and Q358 Base unit. How to read from CPU which module removed from base unit when PLC is runing ? Which address storing diagnostic information?

Hello Experts  I am facing problem with CJ Series Analog I/O module MAD32. The Run LED is Lit, ERC Led is also Lit. what could be the reason?

Dear Experts!!!   Could you please provide me the sample of "QD75MS Module & MR-J3-B program with functional block"    As you can see the page no. 3  in the attached document  "KI-Doc_QD77MSXX_MR-J3-XXBS.Zip" sample is there but i am not able to find it anywhere.   Or if you have any otherone please share it.   Please help!!!

  In this first picture is a numerical input with a monitor device D2058. In the whole GOT project this is the only device that saves the information inputed.   Then on que PLC sequence theres an instruction moving that device's value gotten from the GOT to the position module's buffer memory. My doubt comes when there's another device D10022Z9 getting the same value of D2058. In this case the Z9 index is always 0, I checked. In the whole PLC program this is the only part where the D10022Z9 appears, there is no instruction anywhere copying D2058 to D10022Z9 which is how I would think is the way it has the same data always. Am I missing something or how is this possible?  

PAROCK1 for HMI/SCADA View File Now a software solution is available for your Modbus (MB) needs in Rockwell/Allen-Bradley Control Logix or Compact Logix (Clgx) family processors, instead of a traditional 3rd party hardware like Prosoft MVI-56, Molex SST-SR4-CLX-RLL etc.  It is an Add-on instruction (AOI) for PLC/PAC firmware v16 or later, (other solutions are available for pre v16 systems).  For hardware interface, use PLC’s channel 0 (serial) or TCP/IP Interface module(s) to have as many MB TCP/IP devices or serial devices.  (Some limits apply based on system configurations, Comm. settings depending on HW used.) Connect any MB Client/Master or Server/Slave device(s) to your CLgx PLC, including flow computers, analyzers, VFDs, Power Monitors, Level gauges, Smart I/O, etc.  All the MB public/native function codes are supported.  32-Bit integers/floats as single entity are supported with byte and word level swapping. A separate utility automates the data mapping to your PLC logic.  Features -Serial Master (BASIC required Option); TCP; Slave; Redundancy; More than 5000 accumulative registers; MB CFC (Custom/Private Function Code) Support; Data mapping too – Between PAROCK1 & your PLC logic; Packaged with Rockwell; TCP/IP Interface Module; Volume Discounts; Annual Support Requirements -Rockwell/AB-CLgx processor with v16 or later.  Contact PCI for earlier versions. -If using CPU’s Chan0, you cannot use Chan0 for any other user mode activity.

Hi all, Quick question about adding ENET modules to a plc. If I have a local network of a HMI, PLC and 1 device all on IP 192.168.255.x and I have another device across the plant with an address of 171.27.19.x, can I add that one device to the PLC and it will recognize it? Is there a way to add a device with a totally different IP address to a PLC that is already set up?

Hi all. I have a B&R PP420 panel, some I/O on the X2X and 4 Acopos servodrives /servomotors. Successfully created and tested 4 axes, they work OK, control via NCtest or X2X IN, or PP420 display. But creating CNC system is the problem... On NCtest, I have errors, and no move. Error 7742: ACP10_MC FB error or aborted Info: Axis Index [0] Info: ACP10_MC FB error number [29226] Info: Command aborted [0] Info: ACP10_MC FB number [1] = MC_BR_MoveCyclicPosition (cyc. pos.) On SDM, axis error: 32274 Network coupling: The broadcast channel was not configured Can someone help? Thanks.svinaga@yahoo.com Foto errors.pdf

Hi All, I have problem about programming serial module Mitsubishi PLC using QJ71C24N. If I unconnect the cable from the module and connect again it show SIO error and the communication become lost or not sending data again. so i have to restart the PLC to make it normal again. Any other solution for solve this error without restart the PLC? Thanks Husanto

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.

Hey guys. New to the forum and new to plcs. I am running into problems quick, fast and in a hurry. Please be patient. I have created a new project. I have added module 1756 ENBT because that is what I will be connected to. On the chassis there is another ether net card which runs to a switch. That switch runs to a 1734 aent card. I have added this module, 1734 aent, as well to my project. Now I must add a 1734 IB8S and a 1734 OB8S. These are not appearing in my list. I proceeded to download and install these add on profiles. After installation, however, I can still not select the I/O modules. Why is that? And how do I fix it? Thanks in advance, HotPie
