I'm receiving an array of words through a Modbus read operation. Within this array, two specific words represent a real value. Typically, I can concatenate these two words and assign them to a "Real" typed variable to obtain my real data, provided that both the source and destination have addresses. However, I'm encountering difficulties when either the source or destination lacks an address; in such cases, I am unable to perform this concatenation without triggering a datatype mismatch warning in Machine Edition. My goal is to eliminate all warnings, and I ultimately want to execute this process within a Function Block, which is why the absence of addresses is critical. Does anyone have insights on how to convert IntValue[0] and IntValue[1] into RealValue when neither has an address?
In response to my earlier question, I realized I had not explored all possible solutions initially. My effective approach involved using a Move_Bool of 32 directly from InValue[0] into the inputs of a Move_Real to RealValue. This method successfully avoided any warnings in the ME system.
It sounds like you're dealing with a tricky situation! If you're trying to convert the two int values into a real value without addresses, consider using a temporary variable within your Function Block. You can perform the concatenation by using bitwise operations to combine the two integers into a single real value (like handling the byte order appropriately) before assigning it to your Real variable. Just make sure your system can handle the conversion correctly, and double-check your datatype compatibility to avoid those warnings. If you're still stuck, you might want to look into using a custom function that handles this specifically for cases without addresses!
