9. BRODERSEN INTRODUCTION The Remote Master Module UCB xxxx RM is a Bitbus Master module having both BITBUS and Modbus Slave for serial communication The module can be used as a Remote Networking module in a RTU network or and as a Bitbus Master module in a standalone Bitbus application system The Modbus interface can be used to programme control and monitor the remote unit either directly or via a hayes compatible dial up modem connections The Remote Master has a BITBUS interface that enables the master to control a number of BITBUS slave modules including Bitbus Slave modules with Datalogging facilities IEC 1131 3 programming facilities via BCONW are used for control of the BITBUS communication and the logical control including dial up procedures via modems The application program can be developed down loaded and de bugged through the RS232 interface the PC do not require a BITBUS interface a normal COM port can be used When the B CONW programme which can control the process is made and installed in the Remote BITBUS master the RS232 port can be used for monitoring purpose directly or via modem or radio Downloading IEC1131 3 BCONW application program to the connected Bitbus Slave modules is also done via the Serial link on Remote Master For Remote Networking the Remote Master can be a part of a RTU network together with the Series 4000 RTU8 modules Logged data in connected Bitbus Slave Datalogging modules can be transferred
