Units Refreshed for
IORF(097) or DLNK(226)
An I/O REFRESH (IORF(097)) instruction that refreshes real I/O data in a
specified word range is available as a special instruction. All or just a specified
range of real I/O data can be refreshed during a cycle with this instruction.
IORF can also be used to refresh words allocated to Special I/O Units.
Another instruction, CPU BUS UNIT REFRESH (DLNK(226)) is available to
refresh the words allocated to CPU Bus Units in the CIO and DM Areas, as
well as to perform special refreshing for the Unit, such as refreshing data
links. DLNK(226) is supported only by CS1-H, CJ1-H, or CJ1M CPU Units.
