Register Instructions
The data type used by the PLC is the MM_Interface struct, which occupies 728 D registers. The start and end addresses of the variables in the struct should be the same as that set in Mech-Vision. When the start address set in the PLC and Mech-Vision is 10000, the register addresses of each variable are shown in the figure below.
The address offset from the start (base) address and descriptions of the registers for each variable are listed in the table below.
| Address offset | Name | Data type | Description |
