ROC800-Series Instruction Manual
Revised July-2017 General Information 1-23
▪ Batch Queuing:
Sequences future batches, if appropriate for your organization. Used
in conjunction with the batching program.
Note: The integrity of metrology results is critical to the measurement
aspects of the ROC800L. You can lock certain configuration
parameters to ensure the accuracy of liquid hydrocarbon
calculations.
1.8 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 ROC800 over a serial or Ethernet port, independently
of the ROCLINK 800 software.
DS800 Development Suite software allows you to program in all five of
the IEC 61131-3 languages:
▪ Ladder Logic Diagrams (LD).
▪ Sequential Function Chart (SFC).
▪ Function Block Diagram (FBD).
▪ Structured Text (ST).
▪ Instruction List (IL).
A Flow Chart language provides a sixth programming language. With
these six languages, FSTs, and built-in functionality, you can configure
and program the ROC800 in an environment in which you are
comfortable.
You can download and implement programs developed in the DS800
Development Suite software in the ROC800 in addition to—or as an
alternative to—FST programs. DS800 software has definite benefits for
programmers who prefer to use the IEC 61131-3 languages, who desire
to multi-drop units in a distributed architecture, or who desire enhanced
program diagnostics capabilities.
Additional DS800 Development Suite software features include:
▪ Cross-reference (bindings) between variables in separate ROC800
units.
▪ Variable Dictionary.
▪ Off-line simulation for diagnostics and testing.
▪ On-line modification of programs.
▪ On-line debugging of programs.
▪ User developed functions and function blocks.
▪ User defined templates.
▪ Creation and support of user defined libraries.
