(b) I/O statuses
These items indicate I/O module information on an I/O slot basis.
The following bits indicate the status of the I/O module of [unit number] - [slot
number]. [0: I/O module abnormal, 1: I/O module normal]

The FL654 allocates the installed I/O modules to the common memory talker and
listener areas in the order of the I/O modules.
Allocation is made in the ascending order of unit numbers and, in the same unit, it is
made in the ascending order of slot numbers. Note that the basic unit is a smallest
unit.
For example, if both the talker and listener areas use Area 2 of the common memory
(both DIP-SW5 and -SW6 are OFF) and the talker block head is set to 04h (TBH = 0,
TBL = 4) and the listener block head is set to 10 h (LBH = 1, LBL = 0) in the
configuration in Figure 7-4, the allocation of the I/O module to the common memory is
as shown in Figure 7-5.
