I get a hardware alarm when I run up my project using the SNMPII driver saying it failed to register SNMP traps (0x182). 

You will need to install and run the SNMP trap handler service in Windows.

To do this in WindowsXP:

1. Install the SNMP trap handler: Control Panel -> Add/Remove Programs -> Add/Remove Windows Components -> Management and Monitoring Tools

Click the checkbox next to that and click on details, make sure SNMP and WMI SNMP support is installed.

2. Start/Restart the SNMP Trap service: Control Panel -> Administrative Tools -> Services -> SNMP Trap Service (Right Click and choose start or restart)

3. Restart Citect Runtime.
