7.1.2 Input Register parameters
Input Registers
are 3X Reference Registers and accessible for reading only; to
read the value set in an input register parameter use the
04 Read Input
Registers
function code (reading of multiple input registers); for any further
information on the implemented function codes refer to the “6.5.1 Implemented
function codes“ section on page 39.
Current position [1-2]
[000-001, Unsigned32, ro]
These registers are meant to show the current position of the device in the
moment in which the request is sent. The output value is scaled according to
the set scaling parameters, see
Scaling function
on page 58. The value is
expressed in counts.
The
Current position [1-2]
input registers are also available as holding
registers at the address 94-95 and accessible by using the 03 Read Holding
Registers function code. For any information refer to page 52.
Speed value [3-4]
[002-003, Signed32, ro]
This attribute shows the current output speed value detected by the position
encoder and calculated every 100 ms.
The value can be expressed in either steps per second or revolutions per minute
according to the setting next the
Speed format [107-108]
registers on page
58.
The
Speed value [3-4] input registers are also available as holding registers at
the address 96-97 and accessible by using the
03 Read Holding Registers
function code. For any information refer to page 52.
Status word [5-6]
[004-005, Unsigned16, ro]
These registers contain the information about the current state of the device.
The eight bits of the Byte 0 show the values currently set in the
Operating
parameters [109-110] registers; while the eight bits of the Byte 1 are used to
signal if any alarm is active. Bytes 2 and 3 are not used.
