  2. QD77GF Error D304

    Hi I hope setting this parameter will help.  
  3. QJ71E71 MODBUS TCP

    Try this Set M100 and hold it until M200 is on. Use M200 to reset M100.
  4. I'm using names all the time and try not to use hardware addresses. But good names are important. Combining discribing names and prefixes are important.  Here ara the prefixes I use.
  5. Hi I agree with Gambit. But if you must change it than you should test the Batch replace function.
  6. WS0 Safety PLC Cable

    Hi WS0-C20R2 (2049581)
  7. Integer to Byte

    Hi Use the BTOW function. 
  8. COMMUNICATIONS

    Hi If normal "slow" communication is ok, you can use CC-Link IF Field Basic. Easy to use and often good enough. No need to buy anything. If you need high speed communication (ca. 1ms) then buy a CC-Link IE Field master and boards for you robot controller. Good luck      
  9. GX Works 3: PIDINIT, PIDCONT

    Good morning Try this exsample. This a FB that uses tht PID funtion and mapps it. Use E-Manual wiever and seach for the PID function for help Good luck   R_PID_FB_v108.gx3
  10. GX Works 3 (R04CPU) Device Memory

    Hi You need to define D3260 (+1) as a Global label first. Then define a local label. And use the EMOV function to transfer the OP value to the local value.    
  11. HMI point table help

    Hi Direct addressing from the GOT to the point table is the way to go.  
  12. Servo MR-J4-_A-RJ Control mode

    Modbus-RTU can't controm the servo in position mode. To control the servo by Modbus-RTU positioning mode is your only solution.
  13. Servo MR-J4-_A-RJ Control mode

    Hi In position control the servo follows the command pulse signal from for example a PLC. In Positioning mode the servo is controlled internally. Point table is a table with pos, speed, acc, dec ..... values and can be executed by DIO. Program mode is small programs also controlled by DIO. Indexer mode is a rot coordinate. These three modes can be controlled by communication. Remember to init the servo amp in Parameter PT34 when using positioning mode.
  14. Hi Have you checked the station number on the servo?
  15. Mitsubishi FX to KInco MD204L comms cable

    Hi The CPU port on FX PLCs is RS422 so you need to implement a converter if you want to use det RS232 port. Or install a RS232 port in the FX PLC.
