# Address syntax for named addresses

Named addresses can be either:

- Non-numbered address

- Numbered address

## Non-numbered address

For addresses that occur in only one location, specify the name of a register within your controller Also known as remote terminal unit, RTU. A generic term for a device that is used to control and monitor one or more processes in field equipment. The most common control and monitoring device in an access control and security system is an access control panel. Other devices include security monitoring panels, elevator controllers, and fire monitoring devices. Controllers include programmable logic controllers (PLCs), loop controllers, bar code readers, and scientific analyzers. See also: C200 controller, control processor, CPM, hybrid controller, network node controller, PLC. simply using the syntax:

    AddressName [Format]

Part | Description
--- | ---
AddressName | Matches an address from the table of non-numbered addresses.
Format | (Optional) Specify only if the device does not use the default format for that address. Different addresses will have different default formats.

## Numbered address

For address types that occur multiple times within the device (for example, more than one analog input), use the syntax:

    AddressName Number [SubAddressName][Format]

Part | Description
--- | ---
AddressName | Name of the address, for example, loop. For address names see the topic titled "Numbered addresses."
Number | The number of the address. For address numbers see the topic titled "Numbered addresses."

SubAddress Name

(Optional) Some types of numbered addresses can have sub-addresses. For example, every loop has a Process Variable Normally abbreviated as PV. An actual value in a process. In the case of an analog point, for example, the PV represents values such as temperature, flow, and pressure. A PV may also be sourced from another parameter or be calculated from two or more measured or calculated variables using a point algorithm. See also: analog point, parameter, point algorithm, PV algorithm, PV clamp, PV period. (PV The process variable. An actual value in a process. In the case of an analog point, for example, the PV represents values such as temperature, flow, and pressure. A PV may also be sourced from another parameter or be calculated from two or more measured or calculated variables using a point algorithm. See also: analog point, parameter, point algorithm, PV algorithm, PV clamp, PV period.) and a Set Point Also known as SP. The desired value of a process variable. Setpoint (SP) is an analog point parameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. (WSP).

Format | (Optional) Specify only if the device does not use the default format. See the topic titled "Data formats."

## Examples

The following example addresses the Process Variable (PV) of the second loop:

    LOOP 2 PV

Process variable for loop 1:

    LOOP 1 PV

## Typical control loop parameter addressing (where n is the loop number)

Parameter | Source Address | Destination Address
--- | --- | ---
Process Variable (PV) | LOOP n PV | Not configurable
Set Point (SP) | LOOP n WSP 1 LSP1 or SP1 can be used if the parameter WSP is unavailable. | LOOP n WSP
Output (OP) | LOOP n OPWORK 2 OP can be used if the parameter OPWORK is unavailable. | LOOP n OPWORK
MODE (MD) | LOOP n LOOPSTAT | LOOP n MODEIN

## Loop tuning constants (possible AUX parameters for a loop point)

Parameter | Source Address | Destination Address
--- | --- | ---
Gain | LOOP n GAIN1 | LOOP n GAIN1
Reset | LOOP n RESET1 | LOOP n RESET1
Rate | LOOP n RATE1 | LOOP n RATE1

## Digital Output values (used on a status point)

ATTENTION: Attention:

Digital Output values reside in table 0. Therefore, they are not applicable for controllers with a Data Table setting of Holding Registers Lower or Holding Registers Upper.

Parameter | Source Address | Destination Address
--- | --- | ---
PV | DO n | Not configurable
OP | DO n | DO n 3 Note that not all devices support writing to digital output addresses. See the topic titled "Digital output control strategies."

## Digit Input values (used on a status point)

Attention:

Digital Input values reside in table 0. Therefore, they are not applicable for controllers with a Data Table setting of Holding Registers Lower or Holding Registers Upper.

Parameter | Source Address | Destination Address
--- | --- | ---
PV | DI n | Not configurable

## Extended loop support for HC900

ATTENTION: This section is not applicable for controllers with a Data Table setting of Holding Registers Lower or Holding Registers Upper.

Note that for LOOPX parameters, you must reference a controller with an Offset of 6,000. For more information about offsets, see the section "HC900 Hybrid controller. and UMC800 controller OFFSET addresses" in the topic titled "Main properties for a Honeywell Universal Modbus controller."

For the HC900 controller, loops 25-32 must be addressed using the LOOPX parameter Also known as point parameter. A unit of information about a point. For example, an analog point includes parameters such as process variable parameter (PV), output parameter (OP) and setpoint parameter (SP). See also: analog point, output parameter, point, process variable, setpoint parameter.. Loop 32 Mode is only supported for Auto/Manual (AUTO-LSP and MAN-LSP). Loop 32 addresses must be added via the custom Modbus map for full support of Mode.

Parameter | Source Address | Destination Address
--- | --- | ---
Process Variable (PV) | LOOPX n PV | Not configurable

Set Point (SP The setpoint parameter of an analog point. The desired value of a process variable. Setpoint (SP) is an analog pointparameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable.)

LOOPX n WSP

LOOPX n WSP or LOOPX n LSP1

Output (OP) | LOOPX n OP or LOOPX n OPWORK | LOOPX n OP or LOOPX n OPWORK

Mode (MD Mode parameter. Also known as mode. - A point parameter that determines whether or not the operator can control the point value. - In a status point, the MD determines whether the operator can control the output parameter. - In an analog point, the MD determines whether the operator can control the setpoint parameter. See also: analog point, output parameter, point parameter, setpoint parameter, status point.)

LOOPX n LOOPSTAT

LOOPX n MODEIN

Loop Tuning constants (possible AUX parameters for a loop point) for loops 25-32:

Parameter | Source Address | Destination Address
--- | --- | ---
Gain | LOOPX n GAIN1 | LOOPX n GAIN1
Reset | LOOPX n RESET1 | LOOPX n RESET1
Rate | LOOPX n RATE1 | LOOPX n RATE1

## Signal tag and variable named address support for the HC900 and UMC800

Signal Tags (read only) with TAG as the named parameter and Variables (read/write) with MATH_VAR as the named parameter may be assigned to analog (floating point) or digital status points. The Variable and Signal Tag list (Tag Information) should be printed out from the controller configuration to obtain the sequential number listing and the data type (Analog or Digital) so that the proper point assignment may be made.

--- | --- | ---
PV | TAG n | Not Configurable

## Digital signal tag example

Parameter | Source Address | Destination Address
--- | --- | ---
PV | TAG n | Not Configurable
