Title: Watchdog Timeouts
Post by: GA Shaffer on January 24, 2018, 05:12:32 PM

Hello,
I am experiencing Watchdog Timeouts with increasing frequency. All help appreciated, Thanks!

T1H-DM1E PLC
Modbus FA-ISOCON controlling 8 VFD's
Analog & Digital Inputs
CTRIO
DC Outputs

27 Stage Based Programs

Average Scan Time is 7 ms
Watchdog is set to 1000 ms

PLC does not restart to normal operation.

S3580, Tue Jan 23 09:18:51 2018, PLC rebooted following hardware watchdog timeout.
S3581, Tue Jan 23 09:18:51 2018, System was turned off
S3582, Tue Jan 23 09:18:51 2018, System was turned on

Thanks
