Alternatively an SPI inter- face enables serial communication between iC-MB4 and the connected microcontroller. Up to 8 BiSS slaves can be accessed. The BiSS devices are con- nected to clock line MA1 and data return line SL1 us- ing RS422 transceivers (Figure 2). The BiSS devices can be connected directly in noise-free environments. A maximum of 8 BiSS slaves is supported, each with their own configurable data sections covering: 1. Sensor data from 0 to 64 bit (for measurement data, flags like alarm and warning, life cycle counter, . . . ) 2. Register data with 128 bytes per slave ID (e.g. for device parameters) iC-MB4 provides two RAM memory banks for each slave, enabling parallel access of the microcontroller while new sensor data is being read in. A 64 byte memory supports register transfers. Sensor data ac- quisition is started by a microcontroller command or via pin GETSENS. Alternatively, iC-MB4 can also read in new sensor data automatically; the cycle time in this instance can be set as required. The end of sen- sor data acquisition and reading is signaled at pin EOT by a high; if faults occur during transmission pin NER signals a low. Errors in communication can be verified by the microcontroller via a status register; a system error message can also enter this register if bidirectional message pin NER is kept low by external intervention. iC-MB4 generates a clock signal for sen- sor communication using an internal 20 MHz oscillator. The clock can also be supplied externally. iC-MB4 is based on the BiSS master IP family MB100_X. controldata Device 1 (Sensor) Master clock/ Last Slave controldata ID 1..N-1 ID 0 sensordata/ MA+ MA- SL- V- V+ SL+ MA- MA+ SLO- SLO+ Figure 1: Point-to-point connection of iC-MB4 to one device with several slaves controldata actuatordata ID N ID N+1..M-1 Last Slave ID 0 ID 1..N-1 Device 2 (Sensor/Actuator) Device 1 (Sensor/Actuator) Master clock/ controldata sensordata/ MA- MA+ V- V+ SLI+ SLI- MA+ MA- SL+ SL- SL- SL+ MO+ MO- MAO- MAO+ SLO+ SLO- SLR- MO- MO+ V- V+ MA+ MA- SL+ SL- SLR+ Figure 2: Example network of iC-MB4 and two devices The device offered here is a multifunctional iC that contains integrated BiSS C interface components. The BiSS C process is protected by patent DE 10310622 B4 owned by iC-Haus GmbH. Users benefit from the open BiSS C protocol with a free license which is necessary when using the BiSS C protocol in conjunction with this iC. Download the license at www.biss-interface.com/BUA |
