HOLDING REGISTERS
* See Coil Table for register mapping and Coil Descriptions for functionality.
Notes:
1. Any registers marked with “——” are unused and will return a value of HEX <8000>.
2. If a value larger than 4095 is written to the AOR register, 4095 will be loaded.
3. TRX delay is the minimum time from the reception of the last character in the
MODBUS Query until the response is started. The minimum delay value is equal to
2 character times (2 msec min.). The user can increase the delay time by writing to the TRX Delay register. Any value written to the TRX Delay register that is
less than the value calculated at power up will be ignored. The TRX Delay value is stored in E
2
PROM memory. On power-up, the calculated value is compared to
the value read back from the E
2
PROM. The greater of the 2 values will be used as the TRX Delay value and will be written to the TRX Delay register.
4. Numeric data is limited to value -19999 to 99999.
5. Numeric data is limited to the value listed for that parameter according to the meter’s literature.
4
Values less than 65,535 will be in (LO word). Values greater than 65,535 will continue into (HI word). Negative values are represented by two’s complement of the
combined (HI word) and (LO word).
