  1. ip problem on fx3

    What's that? Fx3GE or enet module? .1.250 is the default IP when factory shipped... Are you sure you check "write parameters" in the write tab? Maybe you have to cycle the PLC power for the parameters to take effect...

    No need for thanks. This is the purpose of the forum, In most cases, it takes a little push in the right direction to get you out of panic mode. Drinks on me!
  3. Chek this Vijeo Designer tutorial. I beleve it's in 4 parts. Maybe it will answer most of your HMI<-->PLC relation questions: https://www.youtube.com/watch?v=0rtRKJIvtkE&ab_channel=PeteVree 
  4. MR-J4 ability question

    Yep, and the E3ZM have remote input wire for teach sequence. It come's in handy when you write your own PLC program, but it can be used as spare teach button when onboard is damaged without affecting sensor's operation.
  5. S7-300 to GOT Simple

    Confirmed.  The address offsets are correct as the image in post 1
  6. S7-300 data block addressing

    Confirmed.  The address offsets are correct as the image in post 1. I configuged the the numeric displays as numeric inputs in HMI. When i change values in the HMI all appear correctly in the DB monitored via Simatic manager. I was not able to modify the DB values in SImatic manager... just monitor. Case closed. Thanks again.

    In that case mark sensor in dark/bright mode is not gonna work. You need color mark sensor trained for black... Last time i used this and works great: https://www.ia.omron.com/products/family/1990/ Not cheap but compact and extremlly fast </=50 microseconds delay...

    Tested and working... Siemens Ethernet OP communication driver via CP343-1 module.   DIrect access...   Data transfere... from Ch.1 - S7-300, to Ch.2 - IQ-f FX5   There's one feature. When reading Bits the bayts are swapped.   Section 14.4 from here: https://www.allied-automation.com/wp-content/uploads/2015/02/MITSUBISHI_GOT2000-Connection-Manual-Non-Mitsubishi-Product-2-For-GT-Works3.pdf

    Yep, using CR is a sudden stop and it's a mechanical hit for the servo and the machine when applied in full feed speed. It's ok only for the end of feed right before end of decceleration ramp. I would use TSTP signal for decceleration and stop. If the roll feed speed is always the same it will deccelerate and stop on the same address after mark registration. If the feed speed increase the decceleration ramp is longer and you have to adjust mark sensor position. See also section 12.2.2 Interrupt positioning function...
  10. The link you posted is asking for account.... seems like the folder is not shared for public. What is the brand and model of HMI? Does it have phisical interface/port and driver for FX5 (IQ-F series)? If it does you will need to reprogram it to match the devices of the FX5 PLC...

    See sections 4.5, 5.7, 12 and 12.2 from here: https://eu-assets.contentstack.com/v3/assets/blt5412ff9af9aef77f/blte0ae429ccee352bc/61721a24a8ba7e08b31ca662/18fa0c51-e893-11e6-bda6-b8ac6f83a177_MR-J4-A-RJ_MR-J4-03A6-RJ_Instruction_Manual_Positioning_Mode_sh030143c.pdf
  12. S7-300 data block addressing

    Yes i'm using Simatic manager and i have a coppy for the S7-300 program but off cource it's locked by the OEM. But still... i have access to all inputs and can monitor/modify all Q and M that are not used by the sequence program (tested with the Mitsu HMI). I can't find reason not be able to modify not used variables also... I'll test it first thing in Monday. Thak you again Joe E.  
  13. S7-300 data block addressing

    I have all the hardware installed, powered up and communicating with no issue. The problem is that the datablock is not updating any values, because a specific function of the machine is not allowed at this stage. I'm working on an in-house built machine extension based on Mitsubishi platform. I expect authorized personnel from the manufacturer to check and authorize this program function. I try to be as prepared as possible when this happens, so as not to waste valuable time. There's no way to simulate. The only i can think of... can try and write insted of read to specific DB address and lucky enough if DB is not write restricted on my side. I'm able to monitor the DB via SImatic manager. ...I'll try this.
  14. S7-300 data block addressing

    Yes, you are right. i know that from a previous project. i don't think Mitsu HMIs have byte swap option but it's ok. I am dealing with it easly...   If anyone is interested Section 14.4 from here: https://www.allied-automation.com/wp-content/uploads/2015/02/MITSUBISHI_GOT2000-Connection-Manual-Non-Mitsubishi-Product-2-For-GT-Works3.pdf This only applies to Bit Reading When INT, DINT and REAL it is streight forward. Also from previous project i i know that from addres +0.0 to +12.0 it will work fine. I was worried for the offset after +16.0 array... there is 29 more arrays like it in this DB i have to skip and it will be a mess if i do the offsets wrong... Thank you Joe E.
  15. RS485 COmmunication

    I may be wrong, but since the PC side is RS-232 it can only communicate with one device? Or is it solved through driver/software?
