Format code definitions
The address field is part of the tag. It includes a variety of attributes, some of which are required, and some optional. The following tables list the attributes, whether they are required, and their possible modifiers. All parts of a tag are case sensitive. The order of the fields is fixed; and all fields are separated by semi-colons. See About logic codes for templates of constructed tags.
Real-Time Format Code Definitions

|
T (type) Required |
SS = single status DS = double status enumeration ST = string UT = UTC time MV = measured value (float) CM = complex measured value (float) BC = binary counter (integer) |
Temporarily, this may return a string; when Power Operation is upgraded to handle large integers, this will change. |
|
D (module—Micrologic devices) |
B = BCM P = PM M = MM C = CCM |
|
|
M/m/S/s/C/c/I/i (register type) |
M = holding registers in hexadecimal m = holding registers in decimal S = input coil (status register) in hexadecimal s = input coil (status register) in decimal C = output coil (writable only) in hexadecimal c = output coil (writable only) in decimal I = input register (read only) in hexadecimal i = input register (read only) in decimal |

Register Number Modifiers (register number from 1–4) |
u## = ## registers are unsigned, ## is a decimal s## = ## registers are signed; ## is a decimal |
After the modifier, there may be a number indicating scaling factor. See “V,” below in this table. Used for conversion to SI units, this number will be: RegisterValue x scale For SS and DS: there must be a 1U default; the modifier will be a bitmask: - The mask must use hex only, 16 bits/register - Attach the ones, then the zero mask, to the register; if you only have ones masks, just attach them - Only one register cases can be inverted. Add :I after the masks for inversion. |
|
N (scale) |
numerical entries; range is -10 to 10 |
N defines a constant scale; the logic code knows how to use it. |
|
R (scale register)
|
the register number in decimal |
R defines the holding register where the scale is held; the logic code knows how to use it. |
|
E (priority) |
single digit: 1, 2, or 3; default 2 is used if this is not included (1 = high, 2 = normal, 3 = low) |
Defines the priority Power Operation uses in processing data. |
|
V (conversion factor) |
Use scientific notation without the decimal. |
Examples: 354E-3 = 0.354 354E1 = 3540 |
|
L:P (logic code) Required
|
The number that is used comes from the Logic Codes table. |
L:P is the logic code for PowerLogic. Other codes may follow, such a L:I for ION. For logic code descriptions, see About logic codes |
Alarm format code definitions

Attributes |
Modifiers |
Comments |
|
T (type) Required |
ALM = alarm |
|
|
D (module—optional for Micrologic devices) |
B = BCM P = PM M = MM C = CCM |
BCM is straight addressing, and therefore, optional. |
|
F (file) Required |
File number will be in decimal, up to 5 digits |
|
|
Q (unique ID) Required |
Unique ID will be in decimal. |
This number can be huge. |
Control format code definitions rules of operation
These rules are true for predefined and custom codes:
|
Address structure |
Result |
|
C:N;(action) |
If 1, perform action. If 0, undefined. |
|
C:N;(action1);(action2) C:NO;(action1);(action2) |
If 1, perform action1. If 0, perform action 2. |
|
C:NC;(action1);(action2) |
If 1, perform action2. If 0, perform action1 |

|
C (command) Required |
NO = normally open NC = normally closed N = normal operation |
Normal operation does not have a closed/open status. |
|
OPERATE (command word) |
n/a |
Two required for NO and NC. |
