HelGaa posted a topic in NJ Series / Sysmac StudioHello! I am trying to get hold of the bits in a word, i have read that union is the way to go. My problem is that i cant figure out how union works. I have made a union between a word (16bit) and an array(0...15). The way I understood this was that the word now automaticly updates the array so that when the least significant bit in the word should update array and so on. This is not happening. When I monitor the variables I can see the word change, but nothing happens with the array. Have I misunderstood the consept and what should I do to get hold of the bits?
Copy Structure Members to Array of Bytes
innoaloe posted a topic in NJ Series / Sysmac StudioHello Everyone, haven't roamed here for a while. So I'm having a little trouble using the Structure Data Type in Sysmac Studio/NJ. As an independent tool, it is powerful to create user data types, such as Ethernet/IP Tag Link to V680S RFID or any other EIP equipments. And it is way more powerful than the CJ2, since it has the ability for user defined offset, which CJ2 can't do. But the problem is we cannot move/copy the content of the members to any other standard types. For example, I have a structure with 8 BYTE type members. Then I need to send those out via UDP or TCP/IP comms, which Function Block requires BYTE data type. Unfortunately data movement instructions such as MemCopy and AryMove didn't work at all to do the job. This was easily done in CJ2 since we can access each memory content directly. Currently I already resort to use customized Functions which will translates the Structure into BYTE, but that would mean for every different protocols, I need to create a different Function. I have seen this problem posted somewhere in the SS/NJ Improvement Request section, so I wonder has anyone know any update about this matter? Haven't checked the latest update yet (SS v1.14), but I'm certain that in SS v1.13 this feature is still unavailable. Thanks!!!
