Identification:
In addition to the above, the DE-1500 will respond to function code 17 with an
identification string as follows:
Query:
NN 17 CRC CRC
NN = node number, 17 = ID function code, CRC CRC = two byte
Modbus RTU CRC.
Response:
NN 17 07 D E - 1 5 0 0 CRC CRC
NN = node number, 17 = ID fucntion code, 07 = number of bytes
to follow, DE-1500 ( seven byte ASCII ID string ), CRC CRC =
two byte Modbus RTU CRC
Stop/Reset:
Register 40999 can be written to to remotely trigger the STOP & RESET
functions. It will only respond to a single write ( function code 06 ). The stop
Command is 0xAC53. The reset command is 0xBE41.
Remote Keypad Emulation:
The DE has a feature called the "Remote Keypad Emulation" that can be accessed
through function code 20 as follows
Query:
NN 20 KP CRC CRC
NN = node number, 20 = KP function code, KP is the single byte
"Key Press" from the table below, CRC CRC = two byte Modbus
RTU CRC.
"Key Press" Table
00 = NONE ( no keypress, returns
current display )
