The Phase Property loss of communication" doesn't work properly with real PLC"

Summary

The evaluation of the "Loss of connection" formula of batch phases has been changed, so invalid-bit values on any of the variables used in the formula cause the condition to become true. Please note that this check is done independently from the actual formula.

Invalid bit results will only be detected, if none of the formula variables before it are still without a value. So in this case the detection of the communication loss may be delayed until the timeout for establishing the connection is reached.

Information

we have recommended the customer to configure the condition via the value of an internal variable, which requires additional configuration
