Input area 0.00 to 99.15 (100 CHs)
Output area 100.00 to 199.15 (100 CHs)
With CP1L or CP1E, the first 1 or 2 channel(s) of the input and output areas,
starting at 0CH and 100CH, respectively, are reserved by the CPU unit.
As expansion I/O units and expansion units are connected to the CPU unit, input
and output areas are assigned 1 channel at a time, in the order of connection.
• Number of Reserved Channels and Expansion (I/O) Units
CPU unit
Input area
10-point I/O unit 0 CH
14-point I/O unit 0 CH
20-point I/O unit 0 CH
30-point I/O unit 0 CH, 1 CH
40-point I/O unit 0 CH, 1 CH
60-point I/O unit 0 CH, 1 CH, 2 CH
For example, when using a 40-point I/O unit, input areas 0CH and 1CH, and output
areas 100CH and 101CH are assigned to the internal I/O of the CPU unit.
If expansion (I/O) units are connected to the CPU unit, input areas 2CH and later,
and output areas 102CH and later, will be assigned in order.
When the CPU unit is powered ON, input and output channels are automatically
allocated to the input and output areas of the expansion (I/O) units after the
connections are checked.
Changes to the connection order of the units will result in inconsistencies with the
ladder program. Be sure to review the ladder program when changing the unit
connection order.
