• No more than one technological connector may be configured as
pseudo comment per block output.
• A technological connector number may only be assigned once
(checked using CFC).
• It is not permissible to configure a technological connector at a plan
interface connection.
• It is not permissible to configure a technological connector at the
connection (I/O) of a block in a chart, which is to be compiled as
block type.
• A comment can include several pseudo comments, separated by
blanks, followed by "standard" comments text, e.g.
"@TC_1389 @TP_H345 ...
You can read a parameter and output the value using an operator control
device.
The output value corresponds to:
• for block I/O, interconnected with technological connectors, the
number of the technological connector @TC_nnnn
• for block I/O which are not interconnected, the value of the block input
or output
From the parameter documentation of a standard software package, you
can identify whether the output value represents the number of a
technological connector or the value of the block input. It is not possible
to make this differentiation at the operator control device display.
Using BICO technology, you can only change existing interconnections
between blocks, if these interconnections are configured as follows in the
CFC:
• technological connectors @TC_nnnn are configured as pseudo
comments at the block output,
• parameter @TP_Hnnn or @TP_Lnnn is configured as pseudo
comment at the input of a block,
• the blocks are interconnected by connecting an input with pseudo
comment @TP_Hnnn or @TP_Lnnn and an output with pseudo
comment TC_nnnn.
The interconnection is changed using BICO technology, by entering, at
the operator control device, the number of another technological
connector @TC_nnnn as parameter value.
