  1. FX5 PLC FX5-CNV-IFC module.

    Hi, This module is not an intelligent, it's just a converter of bus connectors from FX5UC CPU to FX5U series modules. So this is not neccessary to configure it.
  2. Modbus CRC16 in any FX PLC

    Hello, You can find a code sample in this topic:  http://forums.mrplc.com/index.php?/topic/36694-how-to-calculate-crc-gx-works-3-fx5/  
  3. kHz signal on digital input

    Look at the SPD instruction then scale its result to get a level value.
  4. Q02H Analog Signal scaling GX Works 2

    Dear panic mode, I'd like to take your attention to a one thing. A calculation using the traditional math equation will give a correct result only for limited range of integers (the subtraction of in_max/in_min and/or out_max/out_min should not give a result outside the range of -32768 - 32767). If it's necessary to operate with a full range of integer values (16-bit AD/DA analog modules), another integer arithmetics should be used, that requires more math operations.

    Sorry for delay with answer, just finished a commissioning work with FX5 and full of new uncensored impressions, regarding to Mitsubishi docs/soft. The cooperation with Beijer was not a jift for Mitsubishi. Beijer did a lot for technical support of Mitsubishi products, while Mitsubishi did nothing for that. When several years ago Mitsu has quarelled with Beijer, offended Beijer has deleted all materials related to Mitsu products from own website. And it became a strong strike onto Misubishi ***.
  6. 1. You have not attached the screenshot of RS485 port settings . 2. You have not attached data (comm port settings, modbus address) for E5DC. 3. How the RST M0 command is related to ADPRW and Modbus comm??
  7. FX3U is supplied with instruction for Modbus CRC16 calculation that's named CRC.

    I spent for a one, A ONE WEEK, just to translate a program from L02CPU to FX5. No, its programmer did not use instructions that is supported by L02CPU, but does not supported by FX5... it's just impossibility to convert the old project to a new. It's a lack of software compatibility from the bottom to up. It's a big bullshit. A very stupid management, hired blunt performers.

    Ron_S, it's nothing. I'm sitting at work for a month and a half, which, if Mitsubishi knew how to prepare properly a technical documentation, could be done in two weeks.
  10. Check the length of Snd/Rcv buffers
  11. Two Modbus FX3U-485ADP-MB on one FX3G-40M ?

    FB = Function Block

    For the second MB channel the FB can be used, that is available at ME FA website after registration there  https://gb3a.mitsubishielectric.com/fa/en/
  13. How to calculate CRC? GX Works 3 / FX5

    Differences between Modbus CRC16 and XModem CRC16: Modbus: XOR the data byte with low byte of CRC Right shifting XModem XOR the data byte with high byte of CRC Left shifting  
  14. How to calculate CRC? GX Works 3 / FX5

    The key problem is in this. At present you are processing only very short messages. When the length of messages will increase, the scan time will stretch, that may affect (will effect) to control processes. Despite on it's just a one of sources of input data for control process...
