20.13.8 Data Output Commands
The control will recognize the following data output commands:
POPEN periphery open
BPRNT binary data print (output)
DPRNT decimal data print (output)
PCLOS periphery close
Those data output commands can be used for outputting characters and values of variables. The output
may be accomplished to the memory of the control or to an external data storage device (through a
serial channel).
Opening a peripheral - POPENn
Before issuing a data output command, the appropriate peripheral has to be opened, through which the
data output is to be performed. The appropriate peripheral is selected by number n.
n = 1 RS–232C interface of serial channel
n = 31 memory of control
A % character is also output to the peripheral simultaneously with the opening of the peripheral, i.e.,
each data output begins with a % character.
Binary data output - BPRNT[...]
The command will send the characters in ISO or ASCII code (depending on the parameter setting); the
variables will be output in binary form.
BPRNT[ a #b [c] ... ]
number of digits below the decimal point
