The E2PROM error bit is activated during the operating phase when a checksum error is detected in an E2PROM page. The FLASH error bit is activated during the start-up phase when a checksum error is detected on the FLASH memory.

Validity of the status and diagnostic bit (0 = Invalid / 1 = Valid) – refer to register 113

For example:

Address 0 x 0100 — 16 bits register for bit validity of the following register.

If Bit 0 = 1, then Bit 0 of the following register (Addr 0 x 0101) is valid.
Address 0 x 0101 — 16 bits register for bits corresponding to Boolean status data.

(1) Degraded mode comes into effect:

When the power supply is cut or less than 13.7 Vdc.
In the event of overcurrent (overload or short-circuit) on the Ti24 I/O.

If a short-circuit on an output has caused a change to degraded mode, at the end of the short-circuit, the output is reset to 0 by the electronics: the Modbus client system sends a Modbus message to reset the output to 1 if it was at 1, before the short-circuit.

(2) Internal error mode if an EXT FLASH and/or E2PROM error is detected.

The data is invalid in the start-up phase, degraded and internal error modes. Invalid data include inputs 1 and 2, the power or flow indicator, the operation and running hours counter.

The E2PROM error bit is activated during the operating phase when a checksum error is detected in an E2PROM page.
The FLASH error bit is activated during the start-up phase when a checksum error is detected on the FLASH memory.
