How to perform a soft reboot on an EGX100/200/300/400, PM8ECC or ECC21 card remotely by register writes

Issue
Customer needs to reboot the unit remotely via software, due to the difficulty of being in front of the unit or unable to open to power cycle unit physically. 

Product Line
EGX100
EGX200
EGX300
EGX400
PM8ECC (for PM800 series meters)
ECC21 (for CM4 or CM3 series meters)

Environment
Remotely performing Cycle Power/Soft reset/soft reboot by register writes via a Modbus "Tester" software or some other Modbus TCP/IP program (like Modscan).

Cause 
This soft reset can be useful when experiencing issues on the Ethernet side of communications.

Resolution
*Warning: A soft reset to PM8ECC or ECC21 may cause I/O module relays to de energize on the meter. Alarms may pick up or drop out. 
A soft reset to an Ethernet Gateway (EGX) does not clear any settings. The device basically restarts the internal processes and programs. It only causes the device to disconnect any inbound Ethernet connections and will run through the basic startup procedure. The LED's will flash on and off as if the unit is being powered up. This is not the same thing as a Hard reset which occurs only when power is lost to the unit.

For EGX200 and EGX400:
Use the following Modbus Address, Register Number, and Register Command to perform a soft reboot (power reset): 

Modbus Address: 254
Register Number: 8000
Register Command: 32896 (Decimal)
(Use address 254 and write a decimal 32896 to register 8000)

    

For EGX100 and EGX300:
Use the following Modbus Address, Register Number, and Register Command to perform a soft reboot (power reset): 

Modbus Address: 254
Register Number: 2800
Register Command: 1110 (Decimal)
(Use address 254 and write a decimal 1110 to register 2800)


For PM8ECC and ECC21:
Use the following Modbus Address, Register Number, and Register Command to perform a soft reboot (power reset): 

Modbus Address: This is the unit ID on Comm 1 
Register Number: 8000
Register Command: 1110 (Decimal)
(Use address 'x' where x is the unit id of comm1, and write a decimal 1110 to register 8000)
