Bit element – this is used for printing the state of the designated bit in V-memory or a
relay bit. The bit element can be assigned by the designating point (.) and bit number
preceded by the V-memory number or relay number. The output type is described as
shown in the table below.
# Data format Description
1 none Print 1 for an ON state, and 0 for an
OFF state
2 : BOOL Print “TRUE” for an ON state, and
“FALSE” for an OFF state
3 : ONOFF Print “ON” for an ON state, and “OFF”
for an OFF state
Example:
V2000 . 15
Prints the status of bit 15 in V2000, in 1/0 format
C100 Prints the status of C100 in 1/0 format
C100 : BOOL Prints the status of C100 in TRUE/FALSE format
C100 : ON/OFF Prints the status of C00 in ON/OFF format
V2000.15 : BOOL Prints the status of bit 15 in V2000 in TRUE/FALSE format
The maximum numbers of characters you can print is 128. The number of characters
for each element is listed in the table below:
Element type Maximum
Characters
Text, 1 character 1
16 bit binary 6
32 bit binary 11
4 digit BCD 4
8 digit BCD 8
Floating point (real number) 12
Floating point (real with exponent) 12
V-memory/text 2
Bit (1/0 format) 1
Bit (TRUE/FALSE format) 5
Bit (ON/OFF format) 3
The handheld programmer’s mnemonic is “PRINT”, followed by the DEF field.
Special relay flags SP116 and SP117 indicate the status of the DL05 CPU ports
(busy, or communications error). See the appendix on special relays for a
description.
NOTE: You must use the appropriate special relay in conjunction with the PRINT
command to ensure the ladder program does not try to PRINT to a port that is still
busy from a previous PRINT or WX or RX instruction.
