Allow Bit writingThe Siemens S5 does not support bit write over network. So for writing a bit the element needs to be read from the controller. Then the bit will be changed. On end the element will be written back into the controller. In the PLC program modifies a bit in the same time this information may be lost.
So the factory setting is off for this.
You can turn this on at your own risk.
Best is designing the plant so that no element is written by the controller and over network. Use ANSI charset as defaultIn the past there was the ANSI charset used inside the strings of the plcs. Nowadays UTF8 is used. to be compatible with older PLCs please chech zhis option.
