This allows tag names to be typed in, input tags 1 to 30 being associated with implicit inputs 1 to 30 respectively
and output tags 1 to 30 being associated with implicit outputs 1 to 30 respectively.
Figure 33 iTools display showing input tags.
In the example above, the value of the parameter with the tag ‘Channel 1’ will be written to implicit input 1.
Note:
1. Most PLCs have a data buffer limit of 500 Bytes. The total number of bytes being used is
given by the equation: Total number of data bytes = (tag 10) × the number of
requested tags.
Note:
2. Input data direction is always to the
FEC920
:
in server mode input data is written to the
FEC920
from the client
in client mode, input data is read by the
FEC920
from the server device.
Note:
3. Output data direction is always from the
FEC920
:
in server mode output data is written to the client from the
FEC920.
in client mode, output data is read by the server from the
FEC920
.
