The leading I/O reference number of output coil must satisfy the following
equation:
Leading reference number of output coil = 000001+16n
where n = 0 to 63 for the CPU 20 and
n = 0 to 255 for the CPU30
Leading reference number of output coil = 000001+8n
where n = 0 to 127 for the CPU20 and
n = 0 to 511 for the CPU30
(2) When the reference number of the first output coil is input, the cursor will move
to the field for the reference number of the last output coil and the reference
number will be displayed automatically, indicating the reference number that
can be input. Press the Enter Key to accept the value or change it to the
desired value if necessary.
The last I/O reference number of output coil must satisfy the following equation:
Leading reference number of output coil = 000000+16n
where n = 1 to 63 for the CPU 20 and
n = 1 to 255 for the CPU30
Leading reference number of output coil = 000000+8n
where n = 1 to 127 for the CPU20 and
n = 1 to 511 for the CPU30
