Protege System Controller Reference Manual

ModBUS Slave Service
The ModBUS Slave service has two functions, one of these is to allow remote access to the Protege System
Controller from an Industrial Process Control solution or SCADA (System Control and Data Acquisition) System,
the other is to allow an Industrial Process, PLC or other device to generate reportable actions within the Protege
System Controller (Zone Activation) making reporting of plant and equipment alarms a very simple process.
To program the ModBUS slave service ensure that the service that has been selected is halted. Press the
[ENTER] key until the display shows the service type selection screen.

The ModBUS Slave Service may require the RS232 serial interface to be converted from a RS485
Signal. Ensure the correct interface is used when interfacing to the Protege System Controller and
PRT-COMM. Refer to the communication PRT-COMM installation manual and ACC-485-ISO
documentation.
Service Mode
The service mode determines how this service operates with the system controller. By default a service is set to
start with the operating system. Setting a service to "Start With The Operating System" (Start With O/S) allows
the service to operate automatically, if the system controller is reset or restarts. Manual control of the service
can be set by using the Manual option for the service mode.
SV001 Ser Mode
Start with O/S
Use the [1] and [3] keys to scroll the available operating modes and press [ENTER] to select the operating mode
displayed. For more information about the list control data entry refer to the section List Control Data Entry (see
page 344).
Communications Port Number
The communications interface port defines which serial port the controller will use for communication with the
ModBUS Master Controller or SCADA application. Select the communication port that will be plugged in to the
ModBUS connection.
SV001 Port

Use the [1] and [3] keys to scroll the communication ports and press [ENTER] to select the operating mode
