Toolset Diagnostics
If you need to find an I/O module fault code, use the Toolset to access the data in the system. The
data also includes further data on the system, e.g. temperature, voltages, currents etc.
Open the Toolset, using either your desktop shortcut or the Start menu ( Start | All Programs | Trusted |
Toolset ).
Open the application running in the system by double-clicking on its name.
It is possible to connect to the system using either the processor’s front panel serial port or over
Ethernet via a communications interface. Before connecting to the system, check that the
communications port settings are correct. Select Debug | Link Setup.
If you are using a TC-304 maintenance cable to connect to the processor’s front panel serial port,
check that ‘Communication port:’ is set to COM1 (or whichever serial port you are using on the PC).
Check that the maintenance cable is plugged into the PC serial port and the processor’s front panel
port.
If you are using Ethernet, check that TMR System is selected. This option is at the bottom of the list
and you need to scroll down to see it. Click on Setup and check the IP address is set. Hopefully for
existing site systems, the communications settings will already be set up. Check that the system and
PC are connected to the Ethernet network with addresses on the same subnet.
Ensure the processor keyswitch is turned to ‘Maintain’ if using a Toolset before build 103. Toolsets
before build 103 will not communicate with the system if the keyswitch is in the ‘Run’ position. Toolsets
from build 103 will communicate read-only if the keyswitch is in the ‘Run’ position.
