Manual Mode Registers

40036

Manual Mode Register (MMR)

Read/Write Bit State: 0 = Auto Mode, 1 = Manual Mode Bit 4 = S1, Bit 3

= S2, Bit 2 = S3, Bit 1 = S4, Bit 0 = Linear Output

40037

Analog Output Register (AOR)

4095

Read/Write Linear Output Card written to only if Linear Output is in

Manual Mode (MMR bit 0 = 1).

40038

Setpoint Output Register (SOR)

N/A

Read/Write

Status of Setpoint Outputs. Bit State: 0=Off, 1=On.

Bit 3 = S1, Bit 2 = S2, Bit 1 = S3, Bit 0 = S4.

Outputs can only be activated/reset with this register when the

respective bits in the Manual Mode Register (MMR) are set.

40039

Reset Output Register

Read/Write Bit State: 1= Reset Output, bit is returned to zero following

reset processing; Bit 3 = S1, Bit 2 = S2, Bit 1 = S3, Bit 0 = S4

SERIAL RLC PROTOCOL COMMUNICATIONS

RLC Communications requires the Serial Communications Type Parameter

(tYPE) be set to RLC Protocol (rLC).

SENDING SERIAL COMMANDS AND DATA TO THE METER

When sending commands to the meter, a string containing at least one

command character must be constructed. A command string consists of a

command character, a value identifier, numerical data (if writing data to the

meter) followed by a command terminator character * or $. The <CR> is also

available as a terminator when Counter C is in the SLAVE mode.

COMMAND DESCRIPTION

NOTES

Node (Meter)

Address

Specifier

Address a specific meter. Must be followed by a

two digit node address. Not required when

address = 00.

Transmit Value

(read)

Read a register from the meter. Must be followed

by register ID character

Value Change

(write)

Write to register of the meter. Must be followed by

Reset

Reset a register or output. Must be followed by

Block Print

Request

Initiates a block print output. Registers are defined

in programming.

Command String Construction

The command string must be constructed in a specific sequence. The meter

does not respond with an error message to invalid commands. The following

procedure details construction of a command string:

1. The first characters consist of the Node Address Specifier (N) followed by a

1 or 2 character address number. The address number of the meter is

programmable. If the node address is 0, this command and the node address

itself may be omitted. For node address 1 through 9, a leading zero character

is not required. (The only exception is a numeric transmission when Counter

C is set for slave mode.) This is the only command that may be used in

conjunction with other commands.

2. After the optional address specifier, the next character is the command

character.

3. The next character is the Register ID. This identifies the register that the

command affects. The P command does not require a Register ID character.

It prints according to the selections made in print options.

4. If constructing a value change command (writing data), the numeric data is

sent next.

5. All command strings must be terminated with the string termination

characters *, $ or when Counter C is set for slave mode <CR>. The meter

does not begin processing the command string until this character is received.

See Timing Diagram figure for differences between terminating characters.

Sending Numeric Data

Numeric data sent to the meter must be limited to the digit range shown under

transmit details 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. (For example: the meter’s

scaled decimal point position = 0.0 and 25 is written to a register. The value of

the register is now 2.5.

Note: Since the meter does not issue a reply to value change commands, follow

with a transmit value command for readback verification.
