Altronics DE-1500 Bedienungsanleitung
DATA LOGGING & MODBUS REGISTERS FOR THE DE-1500
5/8/03
The following document describes the spacing for the fields of the DE-1500 data logging
command.
This command is functional from the RS-232 and the RS-485 data logging port. The
communications settings are 9600, 8, N and 1. The node number must be correct for the
DE-1500 to respond on the RS-485 port. The node number field is ignored on the RS-232 port
and responds accordingly.
The command to access a particular record is as follows:
>(XX DL YYY)
COMMAND HEADER “>” (0) - ASCII value 3Eh.
BEGIN TEXT “(” (1) - ASCII value 28h.
DE-1500 NODE NUMBER (2-3) - This field consists of the node number associated with the
particular DE-1500. The range is from 01 to 99.
SPACE (4), (7) - ASCII value 20h.
COMMAND (5, 6) - The letters “D” and “L”, which stand for “data log”.
REQUESTED RECORD NUMBER (8-10) -
Table I: This value will be between 001 and 100 and represents the requested record number.
Record number 001 will always contain the most recent data log event. Record number 002
contains the second most recent data log event and so on. Requesting record number 999 gives a
response which occurred due to a first fault condition. If there is no faults and 999 is requested,
the “NO DATA AVAILABLE” message occurs. Requesting record number 000 transmits
current status information.
Table II: Table II shows the structure of data log command 998. This is for the Hourmeter.
END TEXT “)” (11) - ASCII value 29h.

The CHARACTER LOCATION for the service messages consists of 20 characters which was
previously programmed into the DE-2510. The HOUR LOCATION describes the position of the
hours associated with the service message or with the hourmeter function. If a service message
is “NOT USED”, then there will be “-----” in the HOUR LOCATION field. Values less than
10000 hours are right justified with spaces in locations to the left. For example, the hour value
of 12345 will be displayed as “12345” and an hour value of 477 will be shown as “ 477”.
Overview:
The DE-1500 includes a RS-232 / RS-485 feature that allows a remote user to
"emulate" the keypad and receive the contents of the display.
Remote Keypad Emulation:
Query:>(01 KP 0)
01 = node number, KP = keypress function, 0 is the single ASCII
"Key Press" from the table below.
"Key Press" Table
0 = NONE ( no keypress, returns
current display )
C = CANCEL TIMERS
T = TEST
R = RESET
S = STOP
P = VIEW
N = NEXT
U = UP/UNITS
V = VIEW CHAN
1 = F1
A = RIGHT/TENS
X = ENTER
L = LEFT/TENS
2 = F2
M = MENU
D = DOWN/UNITS
E = ESC
Response:
CR LF (20bytes 1st line of display) CR LF (20 bytes 2nd line)
CR LF (20bytes 3rd line) CR LF (20bytes 4th line) CR LF
CR = Carriage Return, LF = Linefeed, 4 20 byte ASCII blocks that
is the display. The total number of returned characters is 90.
MODBUS REGISTERS
Communications Paramaters:
All communications are at 9600 baud, 8 Data bits, No Parity, 1 Stop bits. ( 9600 8N1 )
Overview:
The DE-1500 is compliant to the Modicon Modbus RTU standard. The DE-1500
supports DE-1500 Display Modbus Communications
Register reads and data is duplicated for the 30000’s & 40000’s address range.
Maximum number of registers that can be read at one time has been limited to 32.

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.
