W W W . M K S I N S T . C O M Control & Information Technology Type PFB366 PROFIBUS™ SERIAL GATEWAY The PFB366 is a compact RS232 to Profibus serial gateway. The unit is housed in a 2½ x 3¼ plastic housing with mounting tabs. A standard DB9-Female connector provides the Profibus interface and a DB9-Male connector provides the RS232 interface. The Profibus channel is fully isolated from the supplied power. The power is conditioned by a loss-of-ground protection circuit. The PFB366 may be used to interface peripheral devices to a Profibus system. The RS232 serial stream is internally buffered, allowing a Master node to send and receive data using standard Profibus messaging. PFB366 provides a fully buffered serial interface between Profibus and peripheral devices. Internal FIFO’s, buffer up to 255 bytes of receive and 255 bytes of transmit data, easing the interface to slower RS232 based devices. Hardware or software flow control is supported.
