Use of the Hilscher WORD_GET_BOOL function block
Thread Content
It was set to a quantitative type as per the instructions, but an error still occurs; I’m not sure what the problem is
The data type of BITNUM is BYTE. I’ve tried using the constant 5 as well as BYTE#5, but errors still occur
There are several common reasons for errors in this functional block: 1. Check whether the input parameters are correct, especially the address format. Sometimes, an incorrect address format can prevent the function block from being recognized. 2. Verify whether the data types match. Although you say it is set as a volume-based type, it is still necessary to carefully check the input data type required by the function block. 3. Check if it’s a problem with the PLC scanning cycle. Sometimes, a function block requires several scan cycles to read data properly. 4. Check the hardware configuration to confirm that the corresponding IO module is working properly. It is recommended that you first write down the error codes of the function blocks, and then check the manual to find out the specific meaning of those errors; this will make it easier to identify the problem. .
Are the states of each switch point of type WORD?
The function is to extract the status of a certain digit from WORD
I know, I said we need to confirm that the citation point is of WORD type!
