Addressing a Bit Within a Word

This section provides examples of addressing a bit within a word in each
PLC–2, PLC–3, and PLC–5 memory.

To

address a

bit within

a word in:

use this format:

Examples:

PLC-2

memory

$wordaddr/bit

$010/5 (specifies bit 5 of address 010)

PLC-3

memory

$fileaddr:wordaddr/bit

or

$extaddr/bit

$B111:2/3 (specifies bit 3 of word 2 of binary file 111)

$E3.1.8.111.0.2/3 (extended addressing)

PLC-5

memory

$extaddr/bit

$E0.10.2.0/011 (specifies bit 11 of word 2 of file 10)

This section contains examples of programming PLC–2, PLC–3, and
PLC–5 programmable controllers using the MOVE and TMOVE
commands.

The following table contains examples of using the MOVE command to
move a word:

Command line example:

Explanation:

PLC-3 to PLC-2 MOVE FROM :66$010 TO $B2:3 or

M F :66$010 T $B2:3

Transfers word 010 from node 66 to

word 3 of binary file 2.

PLC-3 to PLC-2 MOVE FROM $B2:3 TO :66$010 or

M F $B2:3 T :66$010

Transfers word 3 of binary file 2 to

word address 010 at node 66.

PLC-3 to PLC-3 MOVE FROM :76$I4:50 TO $B2:3 or

M F :76$I4:50 T $B2:3

Transfers word 50 of input file 4

from node 76 to word 3 of binary file

2.

PLC-3 to PLC-3 MOVE FROM $B2:3 TO :76$I4:50 or

M F $B2:3 T :76$I4:50

Transfers word 3 of binary file 2 to

word address 010 at node 76.

PLC-3 to PLC-5 MOVE FROM $B2:3 TO :40.2$E0.10.2.0

or M F $B2:3 T :40.2$E.0.10.2.0

Transfers word 3 of binary file 2 to

word 2 of file 10 in the PLC-5

address 2 connected to KP5 node

40.

PLC-3 to PLC-5 MOVE FROM :40.2$E0.10.2.0 TO $B2:3

or M F :40.2$E.0.10.2.0 T $B2:3

Transfers from word 2 of file 10 in

the PLC-5 address 2 connected to
