HIMA HIQuad Lifecycle & Modernization

HIMA products give you maximum, long-term plant availability. To ensure this, we continually

modernize our product portfolio with new technologies. Compatible successor products ensure

your safety system continues to operate smoothly many years after installation. This reduces life

cycle costs, avoids unplanned downtime, and ensures investment protection for your assets.

HIQuad H41q/H51q was introduced to the market in 1997 as the third generation of central modules

for certified programmable safety systems. In 2018. the fourth generation of central modules was

introduced to ensure the sustainability of the HIQuad system family. The new central modules support

a wide variety of I/O modules from the previous generation. The combination of the reliable HIQuad I/O

modules and the new central modules is named HIQuad X. This guarantees maximum compatibility

for field installations and minimum modernization efforts.

Extensions, Upgrades, and Modernization

Systems, technology, and standards change continuously. To ensure the long-term safety and

availability of your plants, our experts will assist you to keep them up to date during operation.

As part of our modernization services, our experts support you with on-site analysis and advise

you on all options and technologies to keep your plant up to date. This includes consulting on

system upgrades, maintaining your equipment, and updating to compatible successor models.

Our modernization services include upgrade planning, logic conversion from ELOP II to SILworX,

and installing your systems in accordance with the latest safety standards.

Modernizations to HIQuad X will have additional benefits:

• Seamless modernization

HIQuad I/Os including field wirings can be kept as they are, which reduces costs as

compared to new installations. Software engineering is supported through automatic

logic conversion, reducing engineering effort and potential sources of errors.

• Reduced downtime

Unchanged parts can be tested more easily, reducing the downtime required for modernization.

• Modernization flexibility

You have complete freedom to perform modernization in a single step or in multiple phases.

• Improved safety and security

HIQuad X provides you the optimal basis to bring your system to the latest standard of

functional safety according to IEC 61511 and automation security according to IEC 62443.

• Better performance

State-of-the-art technology offers improved features, such as: reduced cycle time,

improved reload capabilities, increased system availability, less engineering effort, and

improved maintenance.

• Continued support:

Products that enter the legacy phase will have limited availability and will not receive updates

or new features. HIQuad X fully supports new safety features and future certifications.
