119. ver A sender can only send on the bus if no other station is sending at that time This is due to the fact that the stations are always listening in to find out whether any messages are being sent to them or any senders are currently active If a sender has started sending it checks that the message it has sent is not corrupt If the message is not changed the send operation continues If the sender detects that its data is corrupt another sender must have already started sending data In this case both senders abort their respective send operations After a random time has elapsed the sender restarts the send operation This is known as CSMAICD and as a random access procedure does not guarantee a response within a certain time frame This largely depends on the bus load which means that real time applications cannot yet be implemented with Ethernet WL MODBUS Communication and Electronic Accessories January 2005 WL Circuit Breaker Short description of WL Circuit Breaker The CubicleBUS Communication Function of the Trip Units The COM16 MODBUS Module Metering and Metering Plus Description of Important Functions Parameters for Communication External CubicleBUS Modules External Power Consumption of a WL Circuit Breaker with CubicleBUS ng WL MODBUS Communication and Electronic Accessories January 2005 Communication capable Circuit Breakers WL Circuit Breaker Introduction and Overvi
