HIMA HIQuad X Series Safety Programmable Electronic System (PES)

6.3 Mandatory Function

Forcing is the process of replacing the current value of a variable with a forced value, used to test user programs or simulate unavailable sensors. Mandatory can run at two levels:

Global forcing: All global variables of the application are forced

Local forcing: The local variable values of a single user program are forced

Time limit: Different time limits can be enforced globally or locally. After the time expires, the controller stops forcing values.

Security Warning:

Mandatory testing can only be carried out after obtaining the consent of the testing agency responsible for acceptance testing

Forcing values may result in incorrect output values

Forcing an extension of the cycle time may result in the watchdog time exceeding the limit

6.4 User Management

The user management in SILworX can set user groups, user accounts, and their access permissions for each project and controller

PADT User Management: Control Access to SILworX Project

PES User Management: Control Access to PES

HIMA recommends using user management to protect SILworX projects and controllers from unauthorized access and network attacks.

Diagnostic system

7.1 LED indicator light

The LED indicator light on the front panel displays the status of the module, and all LEDs should be considered comprehensively. After connecting to the power supply, perform an LED test and ensure that all LEDs light up for at least 2 seconds.

7.2 Diagnostic History

The F-CPU, F-IOP, and F-COM modules store the diagnostic history of faults and other events that have occurred, in chronological order.

Module type Long term diagnosis Maximum number of events Short term diagnosis Maximum number of events

F-CPU 01 2500 1500

F-IOP 01 400 500

F-COM 01 300 700

7.3 Online Diagnosis

The online view in SILworX hardware editor is used to diagnose faults in HIQuad X modules. The faulty module is represented by color changes:

Red: Serious malfunction, such as module not inserted

Yellow: Less severe faults, such as exceeding temperature limits

Lifecycle Management

8.1 Installation Requirements

Grounding: HIMA control cabinets must use large-area functional grounding connections

Shielding: The on-site cables of sensors and actuators must be continuously shielded and grounded at both ends

Surge protection: For digital inputs, shielded input lines or noise suppression in user programs can be used

8.2 Startup steps

Connect to power

Set the system ID and IP address of F-CPU 01 on the left side

Connect the basic rack and expansion rack

Set the mode switch of the left processor module to Stop

login system

Set the mode switch of the right processor module to Stop

Download configuration

Set the mode switch of all processor modules to Run

Execute resource cold start

8.3 Maintenance

HIMA recommends regular replacement of controller fans

Security related applications must undergo regular verification testing

Operating system updates can be loaded into modules through SILworX
