Mode
For normal mode, set the operation mode switch on the front panel of the Unit
as shown in the following diagram, or set bits 00 to 07 in DM word m+18.
The allocation of words and bits in the CIO Area is shown in the following
table.
CJ1W-AD041-V1
Note For the CIO word addresses, n = CIO 2000 + (unit number x 10).
