Note Combine B7A Interface Units and B7A Link Terminals with equal transmission
delay times.
Transmission errors will occur if the transmission delay times used in the com-
bination are not equal.
Do not connect B7A Link Terminals with 10 points and I/O mixed points. Connect
only 16-point transmission models.
1-4 Word Allocation
The CPU treats the B7A Interface Unit as an equivalent number of connected I/O
Units. The words allocation is identical to that for I/O Units, with inputs and out-
puts allocated from left to right.
