4.1.3.1 Computer Settings:
This section shows the communication parameters needed to establish communication with the unit, such as slave
address, communication port, baud rate, parity, control type and startup mode.
Baud rate, parity, data bits, stop bits and ModBus slave address for Com2 (RS232 front port and second serial port in the
rear communication board) are displayed in the default text on the relay main screen.
ModBus Slave Address: ModBus address used for serial and Ethernet communication; default 254.
Communication ports: Ports used in the computer for serial communication.
Baud Rate: Baud rate for serial communication (from 1200 to 115200 baud in EnerVista 650 Setup, from 300 to 115200
baud in relay).
Parity: Parity for serial communication. None, odd or even can be selected.
Control Type: The available control modes are:
• No Control Type, this option selects the serial communication mode, for use with serial communication ports (front
port, RS485, or plastic or glass fiber optic).
• MO
DBUS/TCP, this option selects ModBus TCP/IP communication mode, for communication through the Ethernet port.
In this case, the top right window shows the typical parameters to be programmed; IP address, port address and unit
identifier in the MODBUS TCP SETUP section.
• MO
DEM, this option displays the parameter to set in case of using a modem for the communication, such as Phone
number, Time out (sec.), init. command, type of dialing (tones or pulses).
4.1.3.2 Communication Control:
Located at the bottom of the screen, this section shows the status of communication with the relay. When the relay is not
communicating, the message "650 Setup is not talking to an 650" is shown and the ON button is enabled. Click ON to start
the EnerVista 650 Setup software communicating with the relay.
When the relay is communicating, the message "650 Setup is now talking to an 650" is shown and OFF is enabled. Click
OFF to disconnect communications between the relay and PC.
4.1.3.3 Communication Optimization:
Adjusting the parameters in the Communication optimization section can improve communication, although using the
default values is recommended in most cases. These parameters are the maximum time to wait for a response in the relay
(in ms) and the maximum number of connection attempts to perform before assuming communications failure.
