A-1 Channel/Relay Numbers
In CP1L or CP1E, channel (CH) numbers and relay numbers are specified as described below.
Each channel consists of 16 bits.
Hence, relay numbers are expressed as [channel number] + [bit number (00 to
15)].
Relay numbers are used to handle contacts. Channel numbers are mainly used
as operands for special instructions when processing data by the channel.
Note In CX-Programmer (abbreviated as CX-P below), upper bits of channel
numbers and relay numbers are not displayed if their value is 0. For example,
0000CH will be displayed as 0.
Relay numbers are displayed as a channel number followed by a period and a
bit number. The bit number ranges in value from 00 to 15.
■CP1L CPU Units
*1 H512 to H1535 is FB special area.
*2 For 10/14/20-point I/O units: D0 to D9999, D32000 to D32767.
Note The work words in CIO Area may be assigned to new functions in future
versions of the CPU Units. Be sure to use the work words in W000 to W511CH
first.
