touchwin

Hi Friends ,
I've got a Touchwin touch screen TP-562-TB model.
Where can I get connection cable between Siemens S7-200 cpu 222 PLC and Touchwin touches screen.
Has anybody got the schematic of connection cable between S7200 PLC and Touchwin touches screen?

thanks in advance
 

touchwin hmi

I don't know what interface have the touchwin device and what protocol use. But on S7-200 the interface is RS485 with gnd on pin 5 line A(Tx/Rx+) on 8 and line B(Tx/Rx-) on 3. The protocol is Siemens propietary PPI or MPI depending on settings. If your HMI have a RS485 interface and can use these protocols you can easily connect to S7-200. If HMI not support Siemens protocols, there is a possibility to configure the serial port of S7-200 on freeport mode and try to implement by software the protocol supported by your HMI. Not an easy task.
