A wireless remote control for your PLC. Signals can be controlled via Android
This is a wireless remote control for your PLC. Signals or bits can be controlled via an Android device. The remote has 8 buttons with 3 switch points. Also every buttons has a indicator lamp to display a status from the PLC. On top a text message can be displayed in the upper row.(for example error messages or information for the operator). The graphics on the buttons can be easily exchanged. Examples can be found on my website.
The communication is done via WIFI. The mobile or tablet is sending short UDP telegrams to the PLC. Of course the connection is monitored for disturbance. A CRC check and a MAC ID filtering is also implemented. In such a case the outputs will be disabled. IP address and port for the communication can be changed.
Sample functions blocks are available for following PLCs:
Siemens S7 with CP 343
Omron CS/CJ series
A test software for the PC and samples are available on my website too.
The communication protocol is open, so it is possible to implement any other PLC which can do UDP communication.
Additional software can be found using the link button to my website below.
IMPORTANT: for use in machines please observe the safety regulation of your country.
