Online
The online comms setup allows Ethernet or serial connection. Choose the Ethernet IP address or
serial port number as appropriate.
Choose the automatic diagnostic collection option:
1) None
This just makes a connection and opens the terminal.
2) Choose
This collects enough data to discover the modules fitted in the system and takes only a few seconds. It
then provides a picture or tree of the system which can be clicked on to get data from each module.
2) Not I/O
This collects all diagnostic data from the processor(s), communication interfaces, expander modules
and chassis, which will only take one or two minutes. This information is often the most important, and
is necessary even if the fault is in an I/O module. It also provides a picture or tree of the system, so that
data can be gathered from any I/O module.
3) All
This collects all the above data, but also collects from all the I/O modules. This will take some time,
especially if the I/O module logs are collected. It may be appropriate to ask a user to collect all data, to
avoid needing to explain which data is required.
For a serial connection, use a TC-304 maintenance cable. Check that the maintenance cable is
plugged into the PC serial port and the processor’s front panel port. Ensure the processor keyswitch is
turned to ‘Run’. The Analysis Tool cannot communicate if the keyswitch is in the ‘Maintain’ position. If
the processor front panel port does not seem to work, the Analysis Tool can also be connected to a
communication interface front panel port.
If you are using Ethernet, check that the system and PC are connected to the Ethernet network with
addresses on the same subnet. The keyswitch can be in either position.
On clicking OK, you should see a title line (which assists the analysing code) and a prompt (ci:? for
Ethernet and mp:? for serial). If you only see an empty window or the program reports it cannot make a
connection, there is no communications. For a serial connection, check the cable and the keyswitch
position, then press Enter to request a prompt. For an Ethernet connection, check that the Ethernet
network is connected by sending a ‘ping’ command to the communications interface port using the
‘ping’ command (with the appropriate IP address) in a command window as shown in the Toolset
diagnostics section above. Then try Online | Comms Setup again.
