To evaluated the „Power status” inside the Control application a variable has to be de
-
fined, e.g. „PowerStatus“.
The values of Power status are:
0 Unit isn‘t available (must not appear on functional C6 E22 / P3x)
1 Low charge
2 Half charge
3 Full charge
The Machine application should wait until the micro-UPS is fully charged before any
operation is performed which changes Retains or Persistents. This can be achieved with
an implementation comparable with the following example:
The other “Internal I/O Mapping” variables “24 Vdc power input status” and “24
Vdc power fail counter” cannot be used in a sensible manner, because the PLC
is configuered to stop after a short voltage drop already.
4.7.2 Ip-Scan
Ip-Scan is an IP address scanner from KEB to find other KEB devices in the network.
This requires that Ip-Scan runs also on the device which should be found. The C6 E22
/ P3x should be detectable by the Ip-Scan (also integrated in COMBIVIS studio 6). The
Ip-Scan starts automatically after booting on the device.
Ip-Scan is not yet available on C6 E22 / P3x Linux!
