Embedded fieldbus
For the 1xxxx registers:
•
Additional discrete inputs are added sequentially.
The ACQ550 supports the following Modbus function codes for discrete inputs:
3xxxx Mapping – Modbus inputs.
The drive maps the following information to the
3xxxx Modbus addresses called Modbus input registers:
•
any user defined analog inputs.
The following table summarizes the input registers:
The ACQ550 supports the following Modbus function codes for 3xxxx registers:
4xxxx Register mapping.
The drive maps its parameters and other data to the
4xxxx holding registers as follows:
•
40001…40099 map to drive control and actual values. These registers are
described in the table below.
•
40101…49999 map to drive parameters 0101…9999. Register addresses that do
not correspond to drive parameters are invalid. If there is an attempt to read or
write outside the parameter addresses, the Modbus interface returns an
exception code to the controller.
