Lookout's Modbus Slave Address

[Khalid]

Hi,

It appears that the Modbus Slave (Ethernet) Object in Lookout (6.0.1) doesn't work with an Address (or "Identifier") greater than 127. 

I tried a simple test with the Modbus Object in one process with an address of 128.  And a ModbusSlave Object in another process with its address as 128.  There's no communication.  However, when I make the addresses 127 (or lower), they yak like nobody's business! 

I haven't tested the Serial version though. 

Est-ce un bug?

Hi Khalid,

I just tried to recreate the scenario. I used computer running Lookout 6.0.2 and created a modbus slave object which was connected to a pot object to change values. On a different machine running the same version of Lookout, I created a modbus object and I was able to read data from the modbus slave object. I tested the indentifier values from125 to 255 and they work fine. The objects do not accept values greater than 255 which is as expected. Is there more configuration information that I am missing?

Hi Khalid,

I think I was overlooking the Lookout 6.01 version that you mentioned earlier in your post  ! I was able to recreate the issue that you are facing if I create a modbus slave object in Lookout 6.01 version. Thats a bug! And version 6.02 has a fix for it!

Have a great day!

Thank you Prashanth.  Just downloaded 6.0.2.  And ModbusSlave Addresses > 127 work fine!
