  • Page 77 6. Parameters PART 3 TC218 6. Parameters The TC218 has the memory that stores the control parameters, input type designation, module status information, etc. This memory is called the buffer memory. To access (read/write) this memory from the T2 program, READ and WRITE instructions are used. 6.1 Memory map The contents of the TC218's buffer memory are as follows.
