FAQ

Q: Must the TB840 3BSE021456R1 modules be used in pairs?
A: In redundant configurations, two TB840 3BSE021456R1 modules are typically installed on a redundant base to achieve communication backup.

Q: What is the difference between the TB840 3BSE021456R1 and TB820V2?
A: The TB840 3BSE021456R1 is designed for redundant communication modules (such as CI840), while TB820V2 is mainly used for non-redundant or single-link I/O clusters.

Q: What is the maximum supported distance for the TB840 3BSE021456R1?
A: It supports up to 15 meters using POF fiber, and up to 200 meters when using HCS fiber.

Q: What happens if the address of the TB840 3BSE021456R1 is set to 0?
A: Address 0 is invalid or reserved, and the module will not be recognized correctly by the CPU.

Q: Does the TB840 3BSE021456R1 support hot-swapping?
A: No. Inserting or removing the module will immediately interrupt communication on that channel, so caution is required especially in redundant systems.
