Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

Hi A SINT is a short (signed) integer. It is already only 1 byte - so you should have no problem casting it to a byte like so: bMyByte := TO_BYTE(sintMyShortInt); If you have a regular INT you want to put in 2 bytes - there are a lot of ways you can do this. A Union is certainly one of them. You could have a union with 2 memebers: An array of 2 bytes as one member, and an integer value as another member. Another way would be to look at MEMCPY to put the value into your CAN-message. .. or create a function to take your input value as input, and giving you 2 individual bytes as output. This could be handy if you need to change the byte-order. Integer data types: https://help.codesys.com/webapp/_cds_datatype_integer;product=codesys;version=3.5.17.0 -Bjarne

Hi All, I have hands on rockwell software like rslogix 5000 and studio 5000. Currently started working on codesys i want to know is there any COP instruction with similar functionality in codesys like rockwell. I want to use it to split REAL into 2 INT,DINT to 2 INT also reverse 2 INT into DINT and 2 INT into REAL. Thanks in advance

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
