Description
Data type: Integer
Access: No limitations
The state of the line - whether
it is in use or not. When a line
is not in use, no data can be
transmitted on it, and no data
is received from it. The line
attributes can be read as usual.
Generally, a line must be taken
out of use by setting this attrib-
ute to 0 before the line attrib-
utes can be written. When a
line is stopped by setting the IU
attribute = 0, all data transmis-
sion on the line ceases. How-
ever, before that, the protocol
stack executes to the end all
on-going data transactions. For
example, the polling of the sta-
tion in turn is completed.
Data type: Integer
Access: Read-only
The number of transmitted
telegrams.
Incremented each time a mes-
sage transmission to the Mod-
bus channel fails for some
reason.
The number of transmitted
commands.
The number of transmitted
replies.
