Variables for the S7TCP32 driver may
show INVALID bits for interrupted
communication after reloading the Service Engine. However, the reconnection
works as expected and the number of connections to the PLC is not too high.
This behavior is not desired when reloading. INVALID
bits must not be set if the driver interrupts the connection during reloading.
This may only happen if the subsequent reconnection fails.
This behavior has been modified. The S7TCP32 driver no longer sends an INVALID bit if the connection is first disconnected and then successfully re-established during reload.
To benefit from this fix:
