A-1 Channel/Relay Numbers

In CP1L, 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.

zChannel Data Notation

Channel data is represented by 4 hexadecimal digits, derived from 16 binary digits, representing the ON/OFF state of the 16 bits. In other words, for each 4 bits, the sum of ON bits are calculated and expressed as a single digit.

00001 1 1 101111100

The above channel will be expressed as "0F7C (Hex)".

zConstants Notation

Constants used in CP1L instructions are represented as follows.

Notation Content/Purpose

#0000 to 9999 (BCD) Timer/counter values, BCD arithmetic instruction, etc.

#0000 to FFFF (Hex) Comparison data for comparison instructions, transfer data,

&0 to 65535 Unsigned decimal notation

BIN arithmetic instructions, etc.

(Available in certain special instructions only. Can be loaded into CX-Programmer by converting to and from hex digits.)

zInstruction Execution Conditions

There are 2 types of instructions: cyclic instructions, and differentiated instructions.

• Cyclic Instructions The instruction is executed on each cycle, for as long as the execution condition is ON. Example

(Least Significant Bit)

LSB

Appendix

W00000

• Differentiated Instructions The instruction is executed only once (i.e. on 1 cycle only) when the execution condition turns ON. The instruction name is prefixed with an "@". Example

W00001

Some instructions cannot be specified as a differentiated instruction (with the "@" prefix). If such is the case, use the UP(521)/DOWN(522) or DIFU(013)(differentiated UP)/DIFD(014)(differentiated DOWN) instructions.

MOV (021) H010

D00010

@MOV (021)

H020 D00020

On each cycle for which work area W00000 is ON, data in holding area H010CH is transferred to DM D00010.

When work area W00001 switches from OFF to ON, data in holding area H020CH is transferred to DM D00020.
