PRT-CTRL-SE Protege System Controller Reference Manual | PRT-CTRL-SE 177
Device Address
When the unit is connected to a ModBUS communication network it must have a device address programmed.
The device address is typically provided by the automation company or defined by the SCADA system that is
being connected to. The address is programmed in Hexadecimal and can not be 0x00 or 0xFF.
SV001 Device
address: 01
Type the appropriate 2 digit device address, after each digit you must press [Í] and [Î] to move to the next
digit. When the desired device address is entered, press [ENTER] to save the programmed setting and move
to the next screen. For more information about hexadecimal data entry refer to the section Hexadecimal Data
Entry (see page 335).
i
The device address must be configured for a value below 0xFF and above 0x00, failure to configure
the address to an appropriate value will cause the system not to respond. Duplicate address will
cause communication failures with the ModBUS Master application.
Data Options
The data configure various communication settings that affect the operation of the ModBUS protocol.
SV001 Data
[--------]
To modify options, use the keypad as explained in section Entering Data Options (see page 336).
Option 1 – Log Comm Events
y Enabled the service log communication events that occur on the ModBUS system to the event buffer.
y Disabled the communication events will not be logged.
Option 2 – Log Comm Errors
y Enabled the service log ModBUS Communication errors that occur which relate to the requests of certain
objects and information outside the bounds of the interface.
y Disabled the errors will not be logged and requests that generate errors will be silently discarded.
Option 3 – Reserved
y Reserved do not modify
Option 4 – Reserved
y Reserved do not modify
Option 5 – Remote Buffer View
y Enabled the service will use the remote buffer for the look up of register values. This is used when the
Protege System Controller is used to receive alarms and messages from remote sites that communicate in
the Remote ModBUS protocols.
y Disabled the service will use the local objects (Areas, Doors and Zones) to send status and information.
Option 6 – Remote Zone Write
y Enabled the service will allow specific coil address's to interact with the zones on the system. The zones
start on the first zone expander. This setting allows remote SCADA applications to activate alarms in the
Protege System Controller and report these messages to a standard alarm monitoring station.
y Disabled the coil address's will operate there designated device.
Option 7 and 8 - Reserved
y Reserved do not modify
