A.2.12 Modbus command parameters
Addressing the command parameters
You can use MODBUS function code 0x06 on the command parameters.
Table A- 19 Command parameters
Offset Number
of
registers
Name Unit Format Value range from ... to Access
60000 1 Reset the device to the
factory settings
- unsigned short - W
60001 1 Device reset (without
changing the Modbus
address)
- unsigned short - W
60002 1 Reset maximum values - unsigned short 0 W
60003 1 Reset minimum values - unsigned short 0 W
0 = All
1 = Imported active
energy
2 = Exported active
energy
3 = Imported
reactive energy
60004 1 Reset energy counter - unsigned short
4 = Exported
reactive energy
W
60005 1 Synchronization of the
demand period
Min. unsigned short 1 ... 60 W
60007 1 Acknowledge the diagnostics
bit
1)
(cf. stored bits in
unsigned long beginning
offset 205)
- unsigned short 0 ... ffffh W
0ffh ... 1ffh
Byte 0 = 0 Digital
output 0.0
Byte 0 = 1 Digital
output 0.1
Byte 1 = 0 OFF
60008 1 Switching outputs (if
parameterized)
- unsigned short
Byte 1 = 1 ON
W
60009 1 Switching command for vector
group
- unsigned short High 0 ... 99, Low 0 ... 1
High byte group
assignment
Low byte 1 = ON,
0 = OFF
W
1) The MODBUS master must acknowledge these diagnostics bits.
