GE Multilin B30 Bus Differential System 5-215 SETTINGS 5.2 PRODUCT SETUP55.2.5 COMMUNICATIONSa) MAIN MENUPATH: SETTINGS PRODUCT SETUP COMMUNICATIONSb) SERIAL PORTSPATH: SETTINGS PRODUCT SETUP COMMUNICATIONS SERIAL PORTSThe B30 is equipped with up to two independent serial communication ports. The faceplate RS232 port is intended for localuse and is fixed at 19200 baud and no parity. The rear COM2 port is RS485. The RS485 port has settings for baud rate andparity. It is important that these parameters agree with the settings used on the computer or other equipment that is con-nected to these ports. Any of these ports can be connected to a computer running EnerVista UR Setup. This software candownload and upload setting files, view measured parameters, and upgrade the relay firmware. A maximum of 32 relayscan be daisy-chained and connected to a DCS, PLC, or computer using the RS485 ports.For the RS485 port, the minimum time before the port transmits after receiving data from a host can be set. Thisfeature allows operation with hosts which hold the RS485 transmitter active for some time after each transmission.c) ETHERNET NETWORK TOPOLOGYThe three independent UR ports do not have routing capability and work only on local subnets for the switched networktopology. End nodes can communicate with each other using all supported protocols of the UR family on a local network. Ina routed network, it is recommended to upgrade the UR device used to 7.1x or higher where routing capability throughstatic route settings has been introduced.
