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:
00033 relay output 1 Relay Output 1 Relay Output 1 Relay Output 1
00034 relay output 2 Relay Output 2 Relay Output 2 Relay Output 2
00035 relay output 3 Relay Output 3 Relay Output 3 Relay Output 3
00036 relay output 4 Relay Output 4 Relay Output 4 Relay Output 4
Function Code Description
01 Read coil status
05 Force single coil
15 (0x0F Hex) Force multiple coils
