If your PLC rack contains a CP 541 you might be able to connect it to the operator panel. CP 541 Communications Processor - Industry Support Siemens The reason that the OP 77B can connect to the S5-103U's porgramming port, which supports AS511 communications, is that it has a RS-232 interface (IF1B) that you can use with a TTY-RS-232 cable (with an addes 25-pin to 9-pin adapter). See for example this video: PC/TTY:cable between computer RS232 port and siemens simatic S5 The OP 77A does not support RS-232 communications, so this solution cannot be used. Hope this helps, Daniel Chartier

TREBOL333 Posts: 11 Rating: (0)	dchartier Hola trebol; Como puede ver en la tabla propuesta arriba, un OP77A es compatible con Profibus-DP. Si el bastidor del PLC contiene un CP 541, es posible que pueda conectarlo al panel del operador. Procesador de comunicaciones CP 541 - Soporte industrial Siemens La razón de que el OP 77B puede conectarse al puerto porgramming del S5-103U, que soporta comunicaciones AS511, es que cuenta con una interfaz RS-232 (IF1B) que se puede utilizar con el cable de un TTY-RS-232 (con un 25 addes -pin al adaptador de 9 pines). Mira, por ejemplo, este video: PC / TTY: cable entre el puerto RS232 de la computadora y siemens simatic S5 El OP 77A no admite comunicaciones RS-232, por lo que esta solución no puede utilizarse. Espero que esto ayude, Daniel Chartier Muchas gracias por la información. Fue una gran ayuda.
