Page 6 - 6739389EN/FB JBUS protocol Introduction JBUS protocol can be used to read or write one or more bits or words. In the interest of simplicity , this document describes only the procedures necessary for operation and monitoring of the APC by Schneider Electric unit. Communications are initiated by the master and include a request from the mas ...

6739389EN/FB - Page 7 JBUS protocol (continued) Principle A full understanding of the protocol is only required if the master is a computer that must be programmed. All communications include 2 messages: a request from the master and a response from the slave. Each message or frame containes 4 types of information: ◗ slave address (1 byte) The sl ...

APC 6000 - page 8
Page 8 - 6739389EN/FB Checking received messages on the slave side After the master sends a request containing the slave address, the function code and data, it computes the CRC and sends it as the check word (CRC 16). When the slave receives the request, it stores the message in memory and calculates the CRC 16 to compare it to the received CRC 16 ...

Page 12 - 6739389EN/FB Function 1 1: reading event counters The master and each slave have one event counter . This counter is incremented each time a frame is received and interpreted correctly by the slave (except for function 1 1 itself). A correctly transmitted message increments the counter .
