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.
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 C100 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:
The handheld programmer’s mnemonic is “PRINT”, followed by the DEF field.
Special relay flags SP116 and SP117 indicate the status of the DL250–1/260 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.
