Support Questions / how to deal withe many MODBUS devices on the same Com Port ?

« on: September 22, 2014, 08:57:11 AM »

Dear Archie I am trying to read tow MODBUS devices one with Station ID=100 the other one   with Station ID=101

Connected to Rs485 Bus and connected to the PC Via USB to Rs485 Converter to com5

how can I read each device with a different Station ID ??

I tried to add another ModbusRTUCom2 Driver on the same com5 with a different Station ID But always I can read the one connected to ModbusRTUCom1

it seems like the com is open and not closed after the reading / writing so the second device never get any packet is there any thing wrong that I did ??


what is your suggestion to solve this ?


Thank you so much

About one Problem I found when I Tested the ModbusRTUCom Ver AdvancedHMIBeta363  But I Got no answer

I consider that you are busy too much but I hope you will find some time to read this Topic


Dear Archie the problem is related to Modbus functions 05 & 06

Function 05 Force Single Coil
Function 06 Preset Single Register

Which is as follows  for Single Coil there is no need to send the Number of elements and also the command in this case should be FF 00 For Turning on Not 00 01
And also for Preset a Single Register there are no need to send the number of elements and the data length
So There are  extra characters in the packet that the driver send to the slave over the serial port any way I summarized what I found in the attached picture pleas have a look

Waiting for your reply

Thank you So much
