modem connected to your communication port, you must also specify a
Phone Number.
If you select Modbus Plus Network, you need only specify the remote
device Address.
If you select Modbus Ethernet you must specify the IP address in
addition to Alarm Priority, Poll Rate, Poll Retry attempts, and Receive
timeout.
Address is a slave address and refers to the PLC or RTU address setting as
set on the device dip switches. If devices share a common line, they require
unique addresses (1 to 255).
IP address is the Internet Protocol address for the Modbus slave object you
are communicating with.
Serial port specifies which port the object uses for communication to the
external device. This does not specify the communication type.
Communication type is determined by the Options»Serial Ports…
command.
Data rate, Parity, Data bits, and Stop bits reference the settings on the
hardware device.
The Defaults button replaces the current settings with default values.
Alarm priority determines the priority level of Modbus-generated alarms.
Phone number specifies the number to be dialed if the serial port setting
is configured for dial-up. This number only applies to the individual
protocol object.
PollRate is a numeric expression that determines how often to poll the
device. Modbus then polls the device at the specified time interval.
Normally, this is a simple time constant such as 0:01 (one second). See
Numeric Data Members in Chapter 2, How LookoutDirect Works, of the
Getting Started with LookoutDirect manual for information on entering
time constants.
Poll is a logical expression. When this expression changes from FALSE to
TRUE, LookoutDirect
polls the device. You can use a simple expression
like the signal from a pushbutton, or a complex algorithm.
Retry attempts specifies the consecutive number of times Lookout

attempts to establish communications with a device if it is not getting a
