5.1 COMMON ISSUES
Modbus/OPC client loses communication on/after midnight
The CMS system is designed to perform an automatic daily maintenance reboot. It takes
approximately 5-8 minutes for the system to return to normal operation. We recommend that digital
communication clients use an extended timeout value of 8 minutes or greater to prevent midnight reboot
timeouts.
Modbus/OPC data is not updating
The digital outputs update once every minute. Requesting data faster than one minute will result
in duplicate data points. Intek recommends setting the poll or scan rate of data acquisition system to one
minute.
