Site Readiness
It is the responsibility of others to ensure that site(s)are ready for scheduled work and to coordinate
the presence of technical personnel or specialists required for support to be on site or readily available.
Additional trips and/or site-services resulting from the lack of site readiness may be billed on a time and
material basis.
Standard System Operation Methodologies:
DFS standard methodologies employed throughout the utility's current control system will be used to maintain
operational continuity.
Each device controlled will be done so using software device controllers.Software device controllers have
operator defined Min, Max,and Manual Control set points as well as a Current status in addition to the device
controller basic and operational criteria.The Min and Max set points define in percent the range the devices
are permitted to operate during the automatic process.The Manual Control set point defines the device
operation when called to operate in manual.The Manual Control set point is overridden when the device is
made available to the automatic process.
When applicable, rate or speed of a device will be governed using the process controller in the process
description.
When the process variable instrument registers a value to operate a device based on the Start operation set
point, in excess of 10 seconds,the assigned device will be called to operate.The device will continue to
operate until a Stop operation set point value had been obtained in excess of 10 seconds. When multiple
devices are required to operate,each device will function in a similar manner.
Device controllers with automatic algorithms will maintain the following basic and operational criteria. Each
device will be monitored for Local/Remote(HOA in Auto equals "Remote") and Run Status if available. If a
controlled device is not equipped with a HOA switch it will always be considered in Remote. If a controlled
device is not equipped with a Run Status it will always be considered as operating correctly.The controls for
each device will include a Manual/Auto and either a Stop/Start,Open/Close or other appropriate control.The
digital input from the device's HOA determines its availability for control by the SCADA system, "Remote"
being the permissive signal for SCADA control.The software Manual/Auto control dictates whether the device
will be controlled manually or automatically via SCADA.A device is considered available to the automatic
process when it is in "Remote" and "Auto" and the device has not failed. A device is deemed "failed" when it
has been called to operate by the automatic process and the device status indication has not operated as
expected in excess of 30 seconds.To clear a device fail condition,simply place the device back into"Manual"
or"Local" until the condition has cleared.
All set points residing in the PLC will have default factory values when shipped.The set points can then be
modified by an operator via SCADA or available HMIs as needed. New set point values will be retained in the
PLC in the event of a power cycle.
GRAPHICAL DISPLAYS
Custom graphical displays of telemetry/project data can take many forms.The graphical displays, if applicable,
provided for under this proposal are P&ID type in nature.The screen/displays will show basic process flow and
instrumentation placement relative to this flow. Device control will also be provided using a standardized set
of control objects employed by DFS. Control operators are color coded and used consistently across all DES
customer platforms.Other forms of graphical displays that more closely represent a pictorial view or a physical
representation of the site are available, in addition to the P&ID type displays,for order.

HMI screens are developed during the programming phase of the project.A copy of the HMI screens will be
submitted for review upon completion. If the utility has adopted a graphical standard other than DFS, contact
the DFS project coordinator to provide examples.
HSS-BASED CONTROL PROGRAMMING&COMMUNICATIONS
Hyper SCADA Server(HSS) based programming to control an RTU requires operational communications at all
times. Should communications between the HSS and RTU become lost or interrupted,the automation will not
function or control the RTU. DFS strongly recommends coupling HSS based programming with disseminated
control logic located at the RTU for full control protection.
This project does not contain the recommended protection.
As most data in this project requires data to be exchanged between RTU a full back up control system with
disseminated control logic to make up for any loss of communication cannot be installed,so any offline
condition needs to be evaluated promptly when it occurs.
Additional Details
Hardwired I/O Requirements:
a. All digital inputs to the DFS RTU will be of a dry contact type,terminal connections to be provided by
the MCC manufacture/contractor/customer.
b. DFS digital inputs utilize a 24 VDC battery backed bias. In cases where voltage drop from long wire runs
makes 24 VDC impractical or where existing monitoring of contacts is done with 120 VAC, 120 VAC will
be used.
c. Mixing of multiple sources of power will not be permitted.
d. All digital outputs from DFS RTU will be dry contacts and provide for 120VAC at 10amp capacity.
e. All analog inputs signals will be 4-20mA(preferred) or 0-5VDC, and use Shielded Cable.
f. 4-20 mA signals at minimum to provide 500-ohm impedance drive.
g. All pulse inputs to be dry contact,and mechanically operated.
h. All penetrations must be made to the bottom of the enclosure unless coordinated with DFS prior to
submittal completion.
i. The field terminal blocks in the DFS RTU provide for stranded wire with a maximum size of 12AWG.
Utility Submittal Involvement
A submittal copy will be issued to the utility for review during the submittal phase. Inputs from the
utility are expected to be included with submittal comments and/or approval.
Work to be Performed by Utility/Others:
a. Ensure 120 VAC power is near the location of the DFS RTU for connection to power.
b. Make site and personnel available to operate system as needed when work is scheduled.
c. All required instrumentation devices either exist or shall be provided and installed by others.
d. All required underground locate information must be provided before DFS installation services can be
scheduled. DFS will provide an underground locate information form.The Utility will be the
underground locate Point of Contact.The Utility must provide a contact name and phone number for
use by locate services should they need to gain access to a secured area or are unable to find the site
based on locate info provided by Utility.
