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!

Hello people, i have a task in which i have to read values from S7-300 Data Block via Mitsubishi HMI (S7-300/400 OP communication driver via CP343-1). I don't have much experience with S7 data blocks and i need someone to  confirm if my addresses in the HMI are entered correctly while waiting for the hardware. In other words i need to know if the DB address offsets are coresponding to Word numbers in the HMI. I need to know if i'm undertandig right the Address offset after the array structure... Link to Mitsubishi section Topic with detailed HMI addressing format: https://forums.mrplc.com/index.php?/topic/41888-s7-300-to-got-simple/ Thank you in advance.

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 

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.

Confirmed.  The address offsets are correct as the image in post 1

Hello people, i have a task in which i have to read values from S7-300 Data Block via GOT SImple HMI (S7-300 Ethernet OP driver). I don't have much experience with S7 data blocks and i need someone to  confirm if my addressed in the HMI are entered correctly while waiting for the hardware. In other words i need to know if the DB address offsets are coresponding to Word numbers in the HMI. I need to know if i'm undertandig right the Address offset after the array structure... Thank you in advance.   S7-GOT.GTX S7-GOT.GTX

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...

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...

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...

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

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.  

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.

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.

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?

Just keep adding contacts  to the rung and GXW will automatically do it for you...

I hope it's only temporary...

If more than 1 Ch is set the software first ask you to chose witch one before device and address

Glad to help.

Well... fx2nc-4da i mounted right from the main CPU module and it's controlled and monitored by FROM and TO instructions trough the buffer memory (BFM). Manual link: https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d07601/jy997d07601d.pdf fx3u-4da-adp Is adapter mounted left from the main CPU and it's controlled by special relays and data registers in the main CPU Section 4.1 from here:https://www.allied-automation.com/wp-content/uploads/2015/02/MITSUBISHI_FX3GFX3U-Users-Manual-%E2%80%93-Analog-Control-Edition.pdf You have to reprogram it. In theory you can mount fx2nc-4da to the right of Fx3UC and the original program should work... it's a temporary solution if it's a must to ubgrade to fx3u-4da-adp. You just have to mount it on the same place it was on the Fx2NC to mathc the module number. This will buy you some time to understand how to reprogram...     

Might be a dumb question... after you change to absolute position system, did you preform HPR at least once? After you power up the machine what is the Axis HPR Request flag status (MD.31 bit 3) and HPR Complete flag (MD.31 bit 4) What do you mean by "command position"... current feed value?  

what is this? F3GA ? For the Chinese market or a replica?
