PLC / HMI

Development and programming of PLCs and HMIs for industrial process control and operation

Programming, modernization and standardization of PLCs and HMIs, with structured logic, clear interlocks and screens guided by ISA-101.

ISA-101 guidelines and ISA-18.2 principles

Context

The challenge

Control systems that have grown through successive modifications tend to accumulate undocumented logic, inconsistent screens between machines and alarms configured without criteria. Maintaining or expanding this base takes time and involves risk.

IDUS's PLC and HMI programming work reorganizes this base, with standardization and documentation of the source files.

Benefits

What your operation gains with this work

More control reliability

Reviewed logic and consistent permissives and interlocks reduce operational failures and unplanned shutdowns.

Simpler maintenance

Organized, documented programming shortens diagnostic time and facilitates future expansions.

Clear screens for the operator

ISA-101 guidelines drive screen hierarchy and highlight the information that requires action.

Standardization across equipment

Different machines now follow the same logic, naming and navigation standard.

In focus

Interfaces that guide operator action

HMI screens are developed with a navigation hierarchy, controlled use of color and emphasis on abnormal conditions. The goal is for the operator to quickly identify what requires attention.

Screens following ISA-101 guidelines
Alarms configured according to client criteria and ISA-18.2 principles
Diagnostics accessible directly from the screen

In focus

Documentation and source files delivered

The client receives the technical documentation and source files of what was developed, preserving the autonomy of the internal team and future suppliers.

Technical documentation of logic and screens
Backups and source files
Internal validation testing before delivery

Application

Programming, modernization and standardization of control systems

The PLC and HMI Programming service covers the development, modernization and standardization of control systems and interfaces for industrial machines and processes. The solution structures logics, interlocks, alarms and operator screens, using organized programming practices and ISA-101 guidelines. Where applicable, alarms are configured according to the client's criteria and ISA-18.2 principles.

Business value

Why this can matter to your company

The control system defines how the plant responds to variations and abnormal conditions. When the logic is undocumented and screens do not follow a standard, every intervention depends on whoever knows that equipment. Standardizing and documenting reduces this dependency and shortens maintenance response time.
