Arrays, UDTs and Structures Over OPC UA: What the Client Actually Sees

The TR14_Belt user-defined type listed twice side by side with byte offsets, as built at 28 bytes and again at 32 bytes after a DINT called Jam Count is inserted after the State member, with the six members that changed offset marked in red and the hidden host SINT and pad bytes shown in grey

Arrays, UDTs and Structures Over OPC UA: What the Client Actually Sees Insert one DINT called Jam_Count into the TR14_Belt user-defined type, put it after the State member where it belongs logically, and download to the 1756-L83E. Fault_Code moves from byte 4 to byte 8, and Starts, Run_Seconds, Speed_mps, Motor_Amps and Last_Fault_S each move four … Read more
