mach3 tool remember

[jekran]

the brain is sending the tool number to the plc via modbus after the tool change is ready controled by the plc then the plc send a bit which mach3 recive and conected to input 4 so when mach3 recive input 4 means that toolchange is ready the problem is when i hit the reset the brain send for tool 1

Ok see now what you are doing however not sure I can get the problem.
I used your xml and set to tool 2, shut Mach down and restarted and the Tool DRO was 2, User DRO 2000 was 2 and in the Brain it still said 2 on the mod output so not sure why it would send a call for tool 1 to your PLC. I am wondering if it may be your ladder that is doing this?

i dont think that it is a ladder problem but i will try to check , the problem is as soon i press the reset the user dro 2000 is sending 1 to the plc but now i am trying this at home and as you said it is working properly and now i am realy confused 
shall i uninstall mach3 and try to set up again ?

Check that you dont have any other Brain or macropump etc writing to that DRO when it sees a reset.

Jekran, If I may ask, and now that I won't be hijacking your thread, what PLC are you using and what can you tell me about the modbus interface.  I will eventually be hooking in with a PLC on my setup.

i am using allen bradley micro logics via modbus
if i can help you let me know
