Hello samkcr; Please show us the contents of the DB you use to setup this Modbus job, so we may see how you have formatted it. Have you tried this with a Modbus slave simulation tool, to test it on a PC( you will find many other free offerings on the net, such as ModbusTools or Modscan). Look at how the standard Modbus Function 16 has to be setup, in the following link. This is a generic explanation, and you must see that your implementation in the Siemens environment follows these guidelines: http://www.simplymodbus.ca/FC16.htm Hope this helps, Daniel Chartier |
