SIPROTEC Modbus - Bus mapping 7SJ80/7SK80/7RW80
C53000-L2240-A320-3
Register map Chapters 1.3 to 1.6 define the allocation (in the following also called “mapping“) of the
data objects of the SIPROTEC devices 7SJ80, 7SK80 and 7RW80 to the positions in
the Modbus registers.
The SIPROTEC objects transferred are sorted by register numbers (starting with 1),
e.g.:
The measured value "Ia" is assigned to register 30001 (Input register).
The protection annunciation (single-point indication) "50(N)/51(N) PU" is
assigned to register 10036 (Input Status register).
Note:
The examples shown in this chapter 1.1 do not necessarily correspond to the real
allocation of the objects in the bus mapping.

Note:
•The description of the standard mapping contains the pre-allocation of the mapping
file at delivery or at initial allocationof a mapping in DIGSI to the SIPROTEC device.
•Changes of the allocation and the scaling of the measured values are possible in
adaptation to the concrete installation environment.
•The definition of the data type (double-point indication, single-point indication,
measured value, metered measurand etc.) and information on changing the
allocations and the scaling of the measured values, as well as on configuring the
Modbus as a system interface of a SIPROTEC device in DIGSI are contained in the
"SIPROTEC communication modules, Modbus - Communication profile" manual
(ref. to page 3).

1.3 Coil Status Registers (0X register)
The Coil Status register block allows the Modbus master to scan
•command outputs through the output relays of the devices (external commands),
•manipulation of taggings (internal commands) that can be changed using Modbus.
Furthermore, these registers can be used to execute switching operations and internal
commands.
1.3.1 Registers 00001 to 00018: Double commands
•User-defined double commands with double-point indications as checkback
indication can be routed on these positions as a "Source/destination system
interface" using the DIGSI Configuration matrix.
•Please observe the information in the chapter "Double commands/double-point
indications" of the "SIPROTEC communication modules, Modbus - Communication
profile" manual (ref. to page 3).
Note:
•The allocation of the output relays to the switching devices and to the output
channels is defined during the parameterization of the SIPROTEC devices.
•Depending on the device composition, there may be less than indicated output
relays (and corresponding Modbus registers) available in the SIPROTEC device.

Changing the setting group:
•In order to change the setting group, the value "1" = ON must be transmitted to the
corresponding register of the setting group to be activated.
•Switching ON one setting group automatically switches OFF the currently active
setting group.
•Transmission of the value "0" = OFF is insignificant for the change of the setting
group and is refused by the SIPROTEC device.
Note:
A change of the setting group is only possible via Modbus if the parameter Change
to Another Setting Group (parameter address = 302) has the value Protocol.
Control mode REMOTE:
If the control authority is REMOTE, the "Control mode REMOTE" (LOCKED,
UNLOCKED) provides the option of unlocked control with Modbus.
•Changing the "Control mode REMOTE" to UNLOCKED permits exactly one
unlocked control operation via Modbus.
After execution of the command, the "Control mode REMOTE" in the SIPROTEC
device will automatically be reset to LOCKED.
•A programmed test "Switch in position" for unlocked control operations will always
be executed.
•If, after changing the "Control mode REMOTE" to UNLOCKED, no command is
received by the SIPROTEC device via Modbus for a period of 5 minutes, then the
"Control mode REMOTE" is automatically reset to LOCKED.
•If the "Control mode REMOTE" was automatically reset to LOCKED by the
SIPROTEC device, then this status can be recognized by the corresponding bit in
the Modbus response message.
In this case, the status of "Control mode REMOTE" in output direction
has to be updated by the Modbus master.
