Registering the I/O Table

Key Sequence

To leave the TC area uncleared and retaining Program Memory addresses
00000 through 00122, input as follows:
The I/O Table Registration operation writes the types of I/O Units controlled
by the PC and the Rack locations of the I/O Units into the I/O table memory
area of the CPU (see Section 3-2 I/R Area). It also clears all I/O bits. The I/O
table must be registered before programming operations are begun. As the
I/O table remains in memory, a new I/O table must also be registered when-
ever I/O Units are changed.
Note If "I/OTBL WRIT DISABLED" is displayed, the I/O table cannot be written.
Check the number of Remote I/O Units, duplicate word settings, for Optical
I/O Units, terminators for Remote I/O Systems, or an excess of I/O units.
Check all I/O Units.
When Remote I/O Master Units connected to I/O Link Units, Optical I/O
Units, Remote Terminals, or I/O Terminals are included in the System, word
multipliers (see below) must be registered for the Masters to enable word
allocation.
I/O Table Registration can be performed only in PROGRAM mode.
The I/O verification error message, "I/O VER ERR", will appear when starting
programming operations or after I/O Units have been changed. This error is
cleared by registering a new I/O table.
