2.What is the main purpose of using RG60?

Supported. The

• Block the vacant slots to prevent dust and foreign objects from entering the back panel.
• Provide physical positioning to ensure the stable arrangement of the modules.
• Occupy I/O addresses at the software level to avoid PLC reporting module absence faults.
• Regularize the appearance of the cabinet to meet the requirements of equipment protection and standardization.
• Reserve expansion slots for future replacement of functional modules directly.

3.What would happen if an RG60 cable is not installed in an empty slot?

The

• The system reported a hardware error with an abnormal I/O address.
• The program reported an error. The dust-proof and foreign object prevention function failed.
• Reliability decreased. EMC performance deteriorated.
• Interference increased. Safety risks (electric shock, foreign objects falling in) occurred.
• The module was not securely fixed and was prone to loosen due to vibration.

4.Can RG60 replace the I/O modules of the iQ-R series?
