ROC827 Instruction Manual

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:

ƒConfigure and view Input/Output (I/O) points, flow calculations, meter runs, PID control loops, system parameters, and power management features.

ƒRetrieve, save, and report historical data.

ƒRetrieve, save, and report events and alarms.

ƒPerform five-point calibration on Analog Inputs and Multi-Variable Sensor Inputs.

ƒPerform three-point calibration on RTD Inputs.

ƒImplement user security.

ƒCreate, save, and edit graphical displays.

ƒCreate, save, edit, and debug Function Sequence Tables (FSTs) of up to 500 lines each.

ƒSet up communication parameters for direct connection, telephone modems, and other communications methods.

ƒConfigure Modbus parameters.

ƒSet up radio power control.

ƒUpdate the firmware.

1.6DS800 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.
