For some fieldbus connections (all Slave modules) the base addresses are mapped in the memory region upper DFFFF(hex). So this modules must be ordered with other base addresses. The same situation takes place if more than two or more master modules of same type are used (for more see note below). The order numbers for the modules are:
order number | alternative ISA-address |
|---|---|
Master connection | |
CX1500-Mxxx-0001 | D4000 |
CX1500-Mxxx-0002 | D6000 |
CX1500-Mxxx-0003 | D8000 |
CX1500-Mxxx-0004 | DA000 |
CX1500-Mxxx-0005 | DC000 |
Slave connection | |
CX1500-Bxxx-0001 | D4000 |
CX1500-Bxxx-0002 | D6000 |
CX1500-Bxxx-0003 | D8000 |
CX1500-Bxxx-0004 | DA000 |
CX1500-Bxxx-0005 | DC000 |
Replace xxx with the following number for the requested fieldbus system:
- 200 for Lightbus
- 310 for Profibus
- 510 for CAN-open
- 520 for DeviceNet
- 750 for Sercos (only Master connection available)
 | Two connection modules (master or slave) can be used simultaneously. If more than two connections are needed call Beckhoff Automation GmbH for further information. |
