Data Communication Test Software
Simply Modbus Master
I am developing a software to communicate with a controller which supports modbus. As a preliminary step to test the communication I tried using modscan32 (32 bit). Though I am able to read the values from the holding registers and input registers, i am not able to write into them. When i try to write, i get a message box saying 'response ok'. 118 MB - click to download. Manual-Compiler 7. SimplyModbusSlave7.1Install.zip 8.88 MB - click to download.

Modscan software, free download For Windows 7 32 Bit
I am developing a software to communicate with a controller which supports modbus. As a preliminary step to test the communication I tried using modscan32 (32 bit). Though I am able to read the values from the holding registers and input registers, i am not able to write into them. When i try to write, i get a message box saying 'response ok'. But the written value doesn't get reflected in the controller's display panel and modscan32 shows the previous value.
If the same operation is tried using modscan (16bit) the write operation succeeds and the value is also reflected on the display panel.
what is wrong? is there a difference in the way write queries are formed and executed?
Any clarification would be greatly appreciated
Thanks in advance-
