Conformance Statement

WARNING!

Changing the parameters regarding the configuration of the transmission will only take effect after restarting the unit (except for the registers the value of which is read from the switch).

About COV

All MIX, MINI, and MAX I/O modules support COV (change of value) policy. It means that the module can send a value every time it is changed. COV only works with BI, BO, AI, and AO objects. For Binary Input and Binary Output objects, the values are sent with every change. Analog Input and Analog Output objects have special COV Increment property, which defines additional sending criteria–object’s value is sent if it is changed by the COV increment value.
