Modbus Register MapAppendix D: Modbus Meter Time SetAppendix D: Modbus Meter Time SetThis appendix contains the Modbus Meter UNIX Time Set function of ION meters.Modbus Meter Time SetUnix Time (UTC) Seconds is an unsigned 32-bit value stored in two Modbusregisters. The first register is the high order followed by the low order secondregister. Consult the online ION Programmer’s Reference for a description of theClock Module time format.UTC microseconds is an unsigned 32-bit value stored in two Modbus registers.The first register is the high order followed by the low order second register. Theformat is absolute time in MicroSeconds.Only resolution by seconds is supported when setting Meter Time via Modbus.Modbus Register# of ModbusRegistersDescription Format Properties41926 2 UTC Seconds UINT32 Read / Write41928 2 UTC microseconds UINT32 ReadModbus Time SetTo set the Meter time via Modbus communications do the following:1. Set the ION Clock Module Time Sync Source Register to the Modbus communicationsport.2. Write the UNIX time in seconds as an unsigned 32-bit value to Modbus Registers41926 (high order) and 41927 (low order).Page 51
