1. Overview

This procedure explains how to replace and configure the CAN ID of an AI4CH,DI8CH,DO4CH I/O module in the Gas Detection System.

⚠️ Caution:

• The SPARE module is initially set to the first ID allocated to each module.
• Before replacing a module, ensure that the channel is cleared to prevent communication errors due to ID redundancy.
• Default CAN IDs:
  • AI: 176
  • DI: 101
  • DO: 151

2. Module Replacement Procedure

1. Remove the Connector

   • Disconnect the connector from the module to be replaced.
   • Label the connector separately to avoid misconnection.

2. Remove the Existing Module

   • Detach the module from the panel slot.

3. Install the SPARE Module

   • Insert the SPARE module into the slot of the removed broken module.

3. CAN ID Setting Procedure

1. Log in to Engineer Mode

   • Access the display screen of the Gas Detection System.
   • Enter Engineer Mode.

1. Navigate to I/O Condition Menu

   • On the display screen, click “I/O Condition”.

2. Configure the ID Settings

   • In the I/O Condition Setting Window, update the CAN ID for the replacement module.

   For AI4CH Module:

   • Set "NOW" ID as 176 (SPARE module).
   • Set "NEW" ID as 178 (Replacement module).
   • Set "AVG" to 5.
   • Click Check to confirm the ID setting.
   • Remove the previous module (ID 176) from the system.
   • 

   For DI8CH Module:

   • Set "NOW" ID as 101 (SPARE module).
   • Set "NEW" ID as 103 (Replacement module).
   • Click Check to confirm the ID setting.
   • Remove the previous module (ID 101) from the system.
   • 

   For DO4CH Module:

   • Set "NOW" ID as 151 (SPARE module).
   • Set "NEW" ID as 164 (Replacement module).
   • Click Check to confirm the ID setting.
   • Remove the previous module (ID 151) from the system.
   • 

4. Final Verification

• Ensure the newly assigned CAN ID is displayed correctly in the system.
• Perform a function test to verify communication integrity.

Important Notes:

⚠️ Caution: Incorrect CAN ID settings may lead to communication failures.
