Register Identification Chart
1. Register Names are also used as Register Mnemonics during full transmission.
2. The registers associated with the P command are set up in Print Options
(Module 7). Unless otherwise specified, the Transmit Details apply to both T
and V Commands.
Command String Examples:
1. Address = 17, Write 350 to Setpoint 1
String: N17VM350*
2. Address = 5, Read Input A value
String: N5TA*
3. Address = 0, Reset Setpoint 4 output
String: RS*
Transmitting Data To the Meter
Numeric data sent to the meter must be limited to Transmit Details listed in
the Register Identification Chart. Leading zeros are ignored. Negative numbers
must have a minus sign. The meter ignores any decimal point and conforms the
number to the scaled resolution. (ie. The meter’s scaled decimal point position
is set for 0.0 and 25 is written to a register. The value of the register is now 2.5.
In this case, write a value of 250 to equal 25.0).
Note: Since the meter does not issue a reply to value change commands, follow
with a transmit value command for readback verification.
Transmitting Data From the Meter
Data is transmitted from the meter in response to either a transmit command
(T), a print block command (P) or User Function print request. The response
from the meter is either a full field transmission or an abbreviated transmission.
See Abbreviated Printing (
Abru
) parameter.
Full Transmission
+ These characters only appear in the last line of a block print.
The first two characters transmitted (bytes 1 and 2) are the unit address. If the
address assigned is 00, two spaces are substituted. A space (byte 3) follows the
unit address field. The next three characters (bytes 4 to 6) are the register
mnemonic. The numeric data is transmitted next.
The numeric field (bytes 7 to 18) is 12 characters long. When the requested
value exceeds eight digits for count values or five digits for rate values. Byte 8
is always a space. The remaining ten positions of this field (bytes 9 to 18)
consist of a minus sign (for negative values), a floating decimal point (if
applicable), and eight positions for the requested value. The data within bytes 9
to 18 is right-aligned with leading spaces for any unfilled positions.
The end of the response string is terminated with (byte 19), and
(byte 20). When a block print is finished, an extra (byte 21), (byte
22), and (byte 23) are used to provide separation between the
transmissions.
Abbreviated Transmission
+ These characters only appear in the last line of a block print.
The abbreviated response suppresses the address and register mnemonics,
leaving only the numeric part of the response.
Meter Response Examples:
1. Address = 17, full field response, Input A = 875
17 INA 875
2. Address = 0, full field response, Setpoint 2 = -250.5
SP2 -250.5
3. Address = 0, abbreviated response, Setpoint 2 = 250, last line of block print
