Communication Interface T8151B

Communications data may be filtered, but the filtering is based on internal numbers for ports and
sockets, not any obvious pattern. The first step therefore is to capture all data and identify the socket
and port numbers for the data of interest.
Type ‘c’ to check that filtering is turned off. The three filters should show [off].
trc:?c
Comms logging disabled
Socket filter : [off]
Peer port filter : [off]
Peer IP address filter: [off]
Comms. log empty.
trc:?
Type ‘c 1’ to collect one buffer (128 packets) of communications.
Type ‘c’ to check on the state of the buffer. Repeat this until the buffer has reached 128 packets.
trc:?c
Comms logging enabled - single shot
Socket filter : [off]
Peer port filter : [off]
Peer IP address filter: [off]
128 packets recorded (full)
Type ‘c off’ to stop collection.
Type ‘c d’ to display the buffer. An example segment is shown here with an OPC server on port 2446
and a Modbus Master on serial port 1. For this example, the modbus master will be examined. This is
socket 1, IP 0.0.0.0 and port 0.

To filter for socket number 1, type ‘c sock 1’. The log can also filter for port and IP (e.g. ‘c ip 0.0.0.0’).
Choose filter settings that isolate the desired communications.
Then start the collection again, either a single fill ‘c 1’ or fill continuously until stopped ‘c on’. Type ‘c’ to
check the size of the buffer.
When the buffer is full or an event has occurred that needs capturing, type ‘c off’. Type ‘c d’ to display
the buffer, which will now only show the filtered communications.
