Comm.Output

Function

To transmit data by the data communication function.

Syntax

Comm.Output line number, data[, timeout][, number of data to transmit]

Guaranteed entry

Line number: Designate a line number to transmit by integer type data.If the data is text data, designate by Integer type.
If the data is binary data, designate by variant type.
Data: Designate data to transmit.
Timeout: Designate a timeout period by integer type data. This is an optional value. This should be -1 "= infinite waiting" if this is omitted.
Number of data to transmit: Number of data to transmit
Designate the number of data to transmit by integer type. This is an optional value. This should be "transmit all" if this is omitted.

Number of data to transmit	Data transmission type
Text data	Binary data
> 0	Transmit all	Transmit only designated bite count
= 0	Not transmit	Not transmit
< 0, when omitted	Transmit all	Transmit all

Description

Data is transmitted by the data communication function.
In the text mode, headers and delimiters (signs to delimit texts) for communication are added to the text being sent. The header and delimiter need to be set with the teach pendant beforehand.
For details, refer to the "Displaying and Changing Data Communication Settings Screen (For Ethernet Selection)" of OPERATION GUIDE.

Designated values and meanings for timeout are described below. When time-out occurs, an error of Error Level1 occurs. For detailed information, please refer to "Error Processing Routine".

Designated value	Meaning
>= 0	Waiting for designated time. (Unit ms)
= -1	Infinite waiting.
< -1, when omitted	Waiting according to the default value (parameter designated value)

Example

'!TITLE "Data Transmission by Data Communication Function"
' Transmit data by the line number 1
Sub Sample_CommOutput

  Dim aaa As Variant

  ' Create one-dimensional array of byte type with 10 elements in aaa
  aaa = CreateArray( 10 )

  aaa( 0 ) = &ha2

  aaa( 1 ) = &hFF

  aaa( 2 ) = &h35

  aaa( 3 ) = &h3c

  aaa( 4 ) = &h7b

  aaa( 5 ) = &hFF

  aaa( 6 ) = &hFF

  aaa( 7 ) = &h45

  aaa( 8 ) = &h87

  aaa( 9 ) = &h99


  ' Open line number 1
  Comm.Open 1

  ' Transmit aaa by the line number 1
  Comm.Output 1, aaa

  ' Close line number 1
  Comm.Close 1
