Figure 7: Communications setpoints page
The following setpoints are available.
Slave Address
Range: 1 to 254 in steps of 1
Default: OFF
For RS485 communications, each MX350 IED must have a unique address from 1 to 254.
Address 0 is the broadcast address detected by all IEDs in the serial link. Addresses do
not have to be sequential, but no two units can have the same address or errors will
occur. Generally, each unit added to the link uses the next higher address starting at 1.
RS485 Baud Rate
Range: 9600, 19200, 38400, 57600, or 115200 baud
Default: 115200 baud
This setpoint selects the baud rate for the RS485 port. The data frame is fixed at 1 start,
8 data, and 1 stop bits, while parity is optional.
NTP IP Address
This setpoint is set to the IP address of the external clock source.
NOTE
NOTE: Setting of the NTP IP Address will not function unless Comms Security is set to Disabled.
Ethernet IP Address
Range: standard IP address format
Default: 0.0.0.0
This setpoint specifies the dedicated IP address provided by the network administrator.
NOTE
NOTE: When changing the IP address, power to the relay must be cycled in order for the new IP
address to become active.
Ethernet Subnet Mask
Range: standard IP address format
Default: 255.255.252.0
This setpoint specifies the subnet IP mask provided by the network administrator.
Ethernet Gateway Address
Range: standard IP address format
