Modbus Communication
The CR30 uses Modbus RTU communications to transfer status information
and control signals to Micro800® controllers and human-machine interfaces like
the Allen-Bradley PanelView.
The Modbus configuration of the CR30 is fixed to Modbus RTU slave at
address 1.
For more information on PanelView, refer to the following documents:
• User Manual: 2711C-UM001_-EN-P
• Quick Start Guide: 440C-QS001_-EN-P
Modbus Mapping The CR30 Modbus addresses are mapped to parameters shown in Table 16 . The
addresses in the range of 1…512 can be accessed as coils. The fault log can be
accessed by holding register reads; each address contains 16 bits of data.
