  4. GX Works3 Projectlib Locked

    Hello, I have a problem that I need to solve in a PLC program has it's projectlib locked.  I work for a company that contracted a PLC programmer before my time to program their new version of their control cabinets. The company did not write any specific contract with the contractor and just relied on his work. The guy later delevered a buggy software that is kind of functional (the bugs came up at the commissioning after the guy was paid and now he refuses to help or to provide more consultations). I have as a task to freshen this up and make it work without bugs, the problem is that the Projectlib is locked and I cannot access the source code.  The only thing that I can changes that I can make to the code is to put some logical circuits between the I/O of the already existing function blocks, which solved some problems, but not all and it keeps one of the most important ones as well. Anyways, that's my story, so now my question is, is there and possible way of unlocking the projectlib? Any feedback would be highly appreciated. Thanks in advace!
  5. Hi everyone,  I am new to Mitsubishi PLC. I am trying to see from where Run or speed commands goes to Servo. I have MELSEC FX2M-32MT with FX2N-1PG cards for the Servo and I am using GX Developer 8.91v  Also, I would like to mention that initially I found out that BATT V light was lit so here what I didi. >I replaced the battery within 20 second while powered ON. Before changing the battery I took upload of the program successfully.  >I have cleared PLC memory and re downloaded the program.  > Checked Memory addresses M8005 8006 both are Low.  Now, when I am trying to run  my machine it is not giving output to two Servos while a conveyor operates when started from the HMI so it means program is inside PLC, right ? Program is attached if someone wants to have a look.  labeling mc 300322.rar
  6. I would like to send ascii data  to other devices using RS232 interface. and the example format is "0009" (it is product counter machine marking). how can I do this? I am using q03ude, I usually convert 1001 to ascii using BINDA and use the last data (01). but, when it double word data e.g. : 100009 the last data is 9 and null, not 09

  8. GOT2000 as MODBUS TCP slave

    I have this setup: FX3G CPU connected to GT2103 through RS422 (CH1). GT2103's ethernet port connected to LAN and set up as modbus TCP slave (CH2). I want to read/write PLC word devices using a modbus TCP client, from a PC. The HMI is acting as a gateway between PLC and PC. I used the Device Data Transfer function to send PLC's D register values to GT's internal GD registers. D0....D9 ==>  GD0....GD9 After some tries, I get valid response from the modbus slave. Reading the holding registers 0....9 (40001....40009), I get only zero values. Those registers can be written back with different values, correctly. I'm sure I didn't understand correctly the modbus address mapping to GT's internal memory. Can anybody help me? Thank you.
  9. PLC DEVICE NET

    how to use device net in FX5U SERIES PLC WITH FANUC ROBOT DEVICE NET CARD A20B-8100-0490 /03B
  10. Hello! I just recently started learning about PLC's at University. While using Gx Works 2, how do I turn on auto complete for existing variable names? With this I mean, after creating a variable, for example bSystem_Started, if I want to use it again, what setting do I need to change so that by just typing "bSy", a pop up appears saying the whole name "bSystem_Started", so by just pressing enter it auto completes. Thanks in advance, Greetings, Patrick.

  15. Scada/ Site management

    Hi,  I have basic experience with PLCs but have a degree in electrical engineering. I have landed a job which requires me to advance my plc knowledge. I am based within the UK and need some advice on how to go about a solution to a problem. The site I am doing this for needs a site managment system. The site is within food production, this would be monitoring of mostly trips and faults within a wide range of industrial equipment (Pumps, compressors, fridges). The site is mostly Mitsubishi and would like one centralised portal within the workshop to view all of the equipment availability. Thank you.

  24. Q and iQ-R series

      Hello,  I want to know, if it is worthwhile to transfer from Q series to iQ-R? Currently our equipment is using Q series, which ss a vacuum coating equipment with about 10 power instruments, 20 gas controllers, and pumps and so on. As for the analog and X, Y points, Q is quite capable.   I can not see any advantage to switch to iQ-R, but some people want to. So I want to know,       1. will Q be outdated in the near future?       2. will use iQ-R cost much more than Q? including peripheral units.       3. has iQ-R really been widely adopted?       4. thoug iQ-R may be powerful, I think use multiple middle size CPU's can be more advantageous,              is this right? Many thanks in advance. Ting    
  25. I'm attempting to look at an offline PLC program to see device values (Ts, Ds, Ms). Is this even possible? Are device values saved when saving a program online? Program is for a Mitsubishi FX3U. Using GX Works2 v1.601B. Win10-Pro OS on the computer. I've an AB background (several decades), but only a couple weeks with Mitsu. Unfortunately, the person who originally wrote and maintained these programs isn't available. This is an easy process with AB, but I just hit walls in the Mitsu IDE. Can anybody help?
