Tim,
When setting the communication watchdogs with FieldPoint, there are several places that you must enable the watchdog. If you miss enabling the watchdog in any location, the watchdog will not work. You must enable the watchdog on the network module, (in FieldPoint Explorer, right click on the FP-1600 and choose Edit this Device, set watchdog to Enabled), on the IO module (in FieldPoint Explorer, right click on the FP-TB-10 and choose Edit this device, then choose Enable under Watchdog Configuration), and finally, each channel must be enabled and given a watchdog setting (right click on the FP-TB-10 and choose Channel Configuration, then set the value for each channel that will have the watchdog enabled, and check the Watchdog Enable box for each channel tha
t will have the watchdog enabled). Apply all of the changes and repeat your test. If this does not work, please post which version of FieldPoint Explorer that you are using and what version of firmware is in the FP-1600.
Regards,
Aaron
