Fieldbus control 339
* = Active low
For the 0xxxx registers:
• Status is always readable.
• Forcing is allowed by user configuration of the drive for fieldbus control.
• Additional relay outputs are added sequentially.
The drive supports the following Modbus function codes for coils:
1xxxx Mapping – Modbus Discrete Inputs. The drive maps the following
information to the 1xxxx Modbus set called Modbus Discrete Inputs:
• Bit-wise map of the
STATUS WORD
(selected using parameter 5305 EFB CTRL
PROFILE ). The first 32 inputs are reserved for this purpose.
• Discrete hardware inputs, numbered sequentially beginning with input 33.
The following table summarizes the 1xxxx reference set:
0 0033 relay output 1 Relay Output 1 Relay Output 1 Relay Output 1
0 0034 relay output 2 Relay Output 2 Relay Output 2 Relay Output 2
0 0035 relay output 3 Relay Output 3 Relay Output 3 Relay Output 3
0 0036 relay output 4 Relay Output 4 Relay Output 4 Relay Output 4
Function Code Description
