Citect,bit value for variable tag [Text] - aktywnedzieciaki.info - Interactive Q & A
In TwinCAT you can change the values of variables on the controller in online mode. This overwrites the originally entered value of the variable. There are two different approaches to this - forcing and writing. The abnormal changing of variable values in a PLC program that is running on the controller can result in unexpected behavior of the controlled machine. Depending on the machine being controlled, the machine or workpieces may be damaged or the health and life of people may be endangered. In the case of forcing, TwinCAT writes the value in each cycle so that the variable is permanently kept at the forced value. Forcing must be canceled by the user.
