Figure 5-14: Sample Modbus Slave Unit
Communications: Configures the FMS to send Modbus requests to a specific slave device over either a
serial connection (EIA232 or EIA485) or over TCP/IP. This configuration can be different for each slave
unit.
RTU Station Address: Enter the address of the Modbus Slave device. Be sure this matches the address
programmed on the particular Slave device.
Protocol: The FMS supports three versions of the Modbus protocol.
 Modbus Standard
 Modbus Extended
 JBus
Selecting these options will configure the FMS to send appropriate requests to each slave device. See the
documentation of the slave device for proper configuration.
Description: Enter a description for the Slave device.
Alarm Dial Out: Enter the Phone Number Configuration Entry ID for up to five pager numbers to which
the FMS will send notification when any alarm for this Slave occurs. The Entry ID numbers correspond to
phone numbers configured from the Configure Phone Number links at the bottom of the Modem
Configuration page. Separate the ID numbers with commas. Enter zero to disable. The FMS will dial the
lowest number listed regardless of the order the numbers are listed.
Example: If the Alarm dial out string is set to “3, 5, 1, 0, 0”, the FMS will dial Pager #1, Pager #3
and then Pager #5 when an alarm occurs.

alarm occurs on this Slave. Email addresses are displayed once they are entered on the Email Configuration
page.
