How to Switch Jobs on In-Sight Vision Suite Camera (In-Sight 3800/In-Sight 2800/In-Sight 8900) via Modbus TCP Communication

Procedure to load or change the job on In-Sight Vision Suite camera In-Sight 3800/In-Sight 2800/In-Sight 8900 using Modbus TCP. 

1. Save each job file starting with an integer value between 000–999.
   Example: 01_Job1, 02_Job2, 03_Job3, etc.
2. Enable Modbus TCP on the In-Sight Vision Suite camera as described in the documentation
   How to enable the Modbus TCP communication
3. Modbus TCP supports four distinct address spaces. There are 2 bit address space and 2 word (16-bit) address spaces.
   1. Coil: Bit type address space. Output from PLC, input to vision system
   2. Discrete Input: Bit type address space. Input to PLC, output from vision system
   3. Holding Register: Word type address space. Both Input & Output from vision system
   4. Input Register: Word type address space. Input to PLC, output from vision system

Note : For detailed bit mapping and complete descriptions of each behavior, refer to the documentation.

Loading a Job Using Holding Registers

1. Ensures the camera is online
   Set Bit 40100.7 = HIGH
2. Check the Current Job ID
   Read Register 407000 (WORD format)
3. Set Camera Into Communication Offline Mode
   Set Bit 40000.7 = HIGH
4. Write the Job ID to Be Loaded
   Write the desired Job Number to Register 402000 .Example values: 00, 01, 02, 03, …
5. Execute the Load Command
   Set Bit 40000.4 = HIGH
6. Verify Job Load Completion
   Monitor Bit 40100.5 (Command Completed)
   When HIGH, the job has been successfully loaded.
7. Confirm the Job Loaded
   Re-read Register 407000 to ensure it matches the expected Job ID.
8. Reset Bits
   Turn OFF Bit 40100.7 and Bit 40000.4
