Sir i have same problem with Automan, I think modbus master blocks is working fine 'coz  error parameter did not executed any error number but the problem is it is always busy and no data executed. I read your previous answer with Automan and you stated thier we might used a counter and I'm little confuse with it 'coz I've tried it already but nothings change still no data executed. Can you please explain it deeply sir or can you give me an example. 

Thank You Sir 

Hello,

if I can give you idea, simply if you associate counter with DONE output and you have still BUSY, you'll have never other value in counter as 0, or previous value before init. Pls pay attention to monitor outputs of MASTER block with same condiitions, because you can't be lucky catch that signals, values.

Hi Duris,

Sorry but I'm still confuse, I am new in this field and I'm still learning thru any internet site. That's why I am seeking for further explanation. I don't get the point of putting a counter in done output ? I have a power meter and I want to get the values from the power meter thru a modbus rtu communication. I have CB 1241 RS 485 communication board. My Comm_Load blocks is working fine but my problem is in my master blocks it is always in busy mode. I put an auxiliary ( NO ) and a set output to knew if it is true that the master blocks is done but in a very short time. And yes it's true that master blocks executed in done mode but where the data ??? I didn't receive data from the power meter. Probably the data will stored in Data blocks. But my data blocks is empty. No data executed.

I hope you can help me with this Duris, I'm stock with this program for a week. And I'm hopeless. 

I've attach print screen photos of my program.

Thank You. 

hi,

you know that the information on the Status in case of an Error are only available for one cycle?

you need to check this with save the Status when Error is true.

      U #Error

      JN #0001

      L #Status

      T #MW500  // in MW500 you find the possible error information

0001: NOP

 hope this helps,

regards,
