ATIM_ACW-DINRSM_UG_EN_V2.8
Statement Period parameter (Code 14)
Size and Code (Byte 1)
Value (Bytes
2
and
3
)
0x40|14=0x4e
0x
YY
YY
The value (0x
YY
YY
) is indicated directly in minutes
(
low byte / LSB first). The default configuration and minimum value
is 10 minutes (0x000a). The maximum value is 40320 minutes, i.e. 4 weeks.
Modbus frame parameters (Code 30 to 61)
These parameters are ‘buffered’ parameters: one or more parts of the configuration can be applied/accessed. Refer
to the document ‘ATIM_ACW
-
DLConfig_UG_FR_vx.pdf’ for more details.
The buffer for this parameter consists of 6 bytes, as follows:
Byte 1
Byte 2
Byte 3
Byte 4
Byte 5
Byte 6
Function code
Concatenation
@Slave
@Reg/bit

@Reg/bit

Number of
registers/bits
NOTE
By default, all these bytes are set to 0.
Function code
–
Byte 1
–
bits 0 to 2
This parameter corresponds to the Modbus function code. The possible values in byte 1 for these bits are:
•
0x01 = Function code 0x01, Read Coils.
•
0x02 = Function code 0x02, Read Discrete Inputs.
•
0x03 = Function code 0x03, Read Holding Registers.
•
0x04 = Function code 0x04, Read Input Registers.
NOTE
By default, the value is 0x00. If a frame is activated (number of registers or bits is non-zero) and this value is set to 0x00, this
will cause an internal error when the frames are sent.
