If you select any message line with the mouse, information about the message will be
displayed at the bottom of the screen - the system address, RSSI and CRC (error-check)
status. The “text box” at the bottom middle of the screen decodes the message - that is, it
decodes the message to display I/O channel and value.
You can display the register values in Decimal by selecting “Dec” at the bottom of the
screen. If you select “Dig”, the values will be displayed as a 0 or 1 digital value (1 if the 16-
bit value is greater than 50% - that is, the most significant bit is 1). If you select “Anlg”,
the value will be displayed as a 4-20mA range.
To stop “comms logging”, select the “Stop Comms” box. You can then shut down the
diagnostics screen, or select “Terminal” to go back to the diagnostics menu.
Option e) Add Time Stamps
Time stamps can be added by selecting the “Time Stamps” box. This will allow the current
time and date to be displayed with each message.
The “Comms log” can be saved to a file for future reference by selecting “Log to File”.
Option f) Current System Address only
This option will only display messages that have the same system address as the module you
are monitoring. If you have another system with a different system address these messages
will not be displayed on the screen. This option is useful where there are a lot of systems in
the same area and the comms log is very active with messages from other systems.
Option g) Display Configured Protocol Driver
This option displays the configured Protocol Driver for this unit e.g.
Configured Protocol is: Ethernet TCP-IT
Option h, i, j, k) Enable/Disable Fieldbus Read/Write Area (These options not available
on the Modbus/DF1 version)
This option is used to stop the Fieldbus database from accessing the I/O database. This is
mainly used when trying to read or write image arrays. If the Fieldbus read area “h” is not
disabled when trying to read or write to the I/O registers then the value in the Fieldbus
database will overwrite the I/O register and you may get an incorrect value.
When doing read/write image array and the module has been configured with Fieldbus
mappings, you may need to disable the Fieldbus read area option h. This stops the Fieldbus
database overwriting the radio database.
To stop the Comms logging press the ‘Stop Comms’ and ‘Terminal’ buttons then press
‘enter’ on keyboard to get Main Menu back up on screen. You may also need to press d) to
stop Comms logging.
