6.3 Coil status registers (0X references)
The coil status register block allows the Modbus master:
• command outputs through the output relays of the SIPROTEC
device (external commands),
• manipulation of taggings (internal commands), which can be
changed by Modbus,
• reading the checkback indication and/or the status of output relays
as well as taggings.
Note
The allocation of the output relays to the switching devices and to the
output channels is defined during parametrization 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.
