ROC827 Instruction Manual
Issued Mar-06 General Information 1-16
system keeps time-stamped minute, periodic, and daily data values as well
as yesterday’s and today’s daily minimum and maximum values.
You can collect history values from the ROC827 using ROCLINK 800 or
another third-party host system. You can view history directly from the
ROC827 or from a previously saved disk file. For each history segment,
you can configure the number of periodic history values archived, the
frequency of archiving the periodic values, the number of daily values
archived, and the contract hour.
ROCLINK 800 can create an EFM (Electronic Flow Measurement) report
file that contains all the configuration, alarms, events, periodic and daily
history logs, and other history logs associated with the stations and meter
runs in the ROC827. This file then becomes the custody transfer audit
trail.
The SRBX (Spontaneous-Report-By-Exception) alarming feature is
available for the host communication ports (Local and dial-up modem
ports). SRBX allows the ROC827 to contact the host to report an alarm
condition.
Use ROCLINK 800 to:
Configure and view Input/Output (I/O) points, flow calculations, meter
runs, PID control loops, system parameters, and power management
features.
Retrieve, save, and report historical data.
Retrieve, save, and report events and alarms.
Perform five-point calibration on Analog Inputs and Multi-Variable
Sensor Inputs.
Perform three-point calibration on RTD Inputs.
Implement user security.
Create, save, and edit graphical displays.
Create, save, edit, and debug Function Sequence Tables (FSTs) of up
to 500 lines each.
Set up communication parameters for direct connection, telephone
modems, and other communications methods.
Configure Modbus parameters.
Set up radio power control.
Update the firmware.
1.6 DS800 Development Suite Software
DS800 Development Suite software allows you to program in any one of
the five IEC 61131-3 languages. You can download DS800 applications to
a ROC827 over the Ethernet port, independently of the ROCLINK 800
software.
