1. Set the following data for the operands of the IORD instruction.
C: The first address in the MC Unit with the system parameter to be read.
S: The destination unit number and total number of words for the position
data that will be transferred. Each parameter requires two words.
D: The first word (e.g., in DM Area) where the system parameters will be
written in the CPU Unit.
2. Execute the IORD instruction.
3. The system parameters will be stored in the CPU Unit starting from the
