6.1.7 About COV
All MIX and MINI 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.
