Abort Channel (2001)
The Abort Channel command immediately disconnects an active channel from its remote PLC
and renders the channel idle. The Channel Transfer bit, the Channel Error bit, and the Detailed
Channel Status words for the channel are set to zero.
Example Command Block
Abort Channel 5. Return the COMMREQ Status word to %R10.

Channel number 5
* Word 4 (CRS word address) is the only zero-based address in the Command Block. Only this
value requires subtracting 1 from the intended address.
(Word 7) Channel Command Number:
This command parameter requests that a channel be
aborted. If the command is processed successfully, it will terminate the processing on the channel
by the time success is indicated in the COMMREQ Status word.
(Word 8) Channel Number:
The channel number specifies the channel to be disconnected (1–32
for Series 90-70 PLCs and 1–16 for Series 90-30 PLCs). As a convenient way to abort all
channels, if the channel number parameter is –1 (FFFFH), all channels in use will be aborted. It
is not an error to abort all channels when there are none in use. Neither is it an error to abort an
idle channel.
Note
For the Abort Channel and Retrieve Detailed Channel Status commands, no
actual data is transmitted on the network. Communication occurs between the
client PLC CPU and the local Ethernet Interface only. For these commands, the
actual function is performed locally within the Ethernet Interface and then the
COMMREQ Status word is sent immediately to the CPU.
