The S100 I/O process interface modules for Advant Controller 400 series process controllers come with connection units,

simplifying cable termination and keeping noise and destructive spikes away from the central electronics.

S100 I/O is the central process interface for Advant Controller 400 series process controllers. 

Thanks to built-in cablemarshalling facilities and parallel communication with the host controller, 

it is the right choice for centralized I/O systems and high-speed applications.

The range of process I/O modules is complete, consisting of general purpose digital and analog

inputs and outputs and special interfaces for specialtasks. These specials include pulse counting,

frequency measuring, positioning, motor speed control and communication with other controllers.

All I/O modules provide simple interfacing, accurate -yet fast - control, and easy integration of individual

loops into a comprehensive plant-wide control and supervision system.

The interface modules connect to the process through screw terminals on connection units normally installed inside, at the back of the cabinet.

This solution keeps noise and destructive voltage spikes away from the central electronics and provides a neat and tidy process interface that is easy to maintain.

High disturbance immunity

All modules conform to the highest standards of electromagnetic noise immunity 

and satisfy the requirements of the EU directives 2014/30/EU and 2014/35/EU. 

For the above reasons, S100 I/O is likely to be the best help you can get for putting your control system in touch with your field devices.

Comprehensive self-diagnostics

Comprehensive self-diagnostics continuously monitor the modules and report any errors through LEDs on

the module fronts and through alarm messages and indications to process operator stations.

Malfunctioning inputs can be disabled and simulated by manual entry while failing outputs are deactivated

or driven to a predetermined safe state automatically.

All I/O modules can be replaced while the system is in service. 

Some modules can even be arranged, trans parently into dually redundant configurations forenhanced availability.

Master Update Period

Master update period is the frequency that Harmony Server synchronizes time with 

the underlying Harmony control network. This property is used only when Time 

Synchronization is enabled. The permissible values are 120 to 3540 seconds.

Sending Global Alarm Acknowledgement Messages to the Loop

Enable Tag Acknowledgment Broadcast 

To broadcast an alarm acknowledgement for a specific Harmony tag: 

– Select the Tag Acknowledgment Broadcast Enable check box on the  Harmony Tab of the tag. Selecting the 

checkbox enables the connectivity server to broadcast the alarm  acknowledgement for this tag on the communication highway.  

On-board processing capabilities

The process I/O modules are “intelligent” in the sense that module-related signal and data processing is

performed on board as opposed to centrally, by the CPU of the host controller. Time tagging of events,

filtering and gain control are some examples of board-level tasks. 

This functional distribution improves real-time performance and reliability of the 

system as a whole and maintains processing capacity when the system is expanded.

Message Wait Period

Message wait period is the Period that Harmony Server waits before attempting to 

assume time mastership on the control network. This property is used only when 

Time Synchronization is enabled. The permissible values are between 180 and 3660 

seconds. Additionally, the configured value must greater than the Master Update Period.
