Внутренние регистры WebHMI/en — различия между версиями

Текущая версия на 10:10, 13 июля 2017

The following internal registers are available in WebHMI (for version 1.5 and higher):

Cx - Communication registers

The presence of communication errors on different connections

CDxxx - Connection Disabled registers

Connection status - enabled / disabled. This register allows you to see whether the exchange is disabled for a specific connection. If the exchange is disabled, the system will return 1. If the exchange is not disabled, it will return 0. Recording to these registers allows you to enable / disable the exchange on the desired connection. To disable the exchange, you need to write 1 to the appropriate register.

Dxxx - Data registers

The data in these registers are NOT stored after the reboot.

The user can access 2000 bytes of RAM. The register address is the address of the beginning of the fragment in the memory block.

Depending on the selected data type, a different number of bytes is required per register. So, you can access the register with address D12 as byte. In this case, there will be a reference to one byte in memory. If you access the register with the address D12 as a word (Word), then physically there will be access to two bytes with addresses D12 and D13 of which the word will be composed. In this way, you can access the individual bytes in the desired word or double word. The system does not check the register addresses for intersections or overlays. This control must be performed by the user.

DSxxx - Data static registers

The data in these registers are stored after rebooting. The user can access 2000 bytes in non-volatile memory. The register address is the address of the beginning of the fragment in the memory block.

Depending on the selected data type, a different number of bytes is required per register. So, you can access the register with the DS12 address as a byte. In this case, there will be a reference to one byte in memory. If you access the register with DS12 as the word (Word), then physically it will access two bytes with DS12 and DS13 addresses of which the word will be composed. In this way, you can access the individual bytes in the desired word or double word. The system does not check the register addresses for intersections or overlays. This control must be performed by the user.

Nonvolatile memory is implemented in the hardware revision platform V5.34 and higher.

Tx - Time registers

Hx - Hardware-related registers

Registers for reading WebHMI on-board hardware status

B0 - Sound alert register

With the help of this register you can make sounds of the built-in WebHMI buzzer. A value of 1 to 8 must be written to the register. WebHMI will issue a corresponding number of beeps. After the signals sound, WebHMI stops making a sound. To repeat the sound signal, you need to write down the desired number again in this register. You can write to this register using scripts. So, for example, you can make a squeaking when the connection breaks down or when an emergency situation occurs.

When reading from this register, 0 will always return.

DOx - Digital Output registers

Registers of external solid-state relays (SSRs). When writing to the register, the corresponding SSR will be closed.

With the help of SSR it is possible to organize control of external devices or to transmit signals to external systems. For example, you can connect a security or fire system and send them alarm signals.

Ixxx - Intervals

Interval registers. Usually used in the event conditions. For example, if you want to receive an event that fires every 10 seconds, you can compare the value of I10 with zero (I10 == 0). If you need an interval of 2 minutes then you need to use the I120 register.

Rxxx - Random values

Random number generator. Rxxx = rand() % xxx.

The value of the register with the number xxx is the remainder of the division of the random number by xxx (register address).

Example: R123 will return random numbers in the range from 0 to 122 inclusive.

Lx - Linux-related registers

Some most important metrics of the operating system.

Exxx.xxx - Event registers

Registers of events. If the event X, for which id = Y, is now being executed, then some of its values ​​from registers of the form EY.xxx can be read. Only reading.

You can read the values ​​that are added to the report table. For convenience, each such value is signed directly in the condition editor.

On this screen threre are registers E1.0, E1.1, E1.2. When the event is now on, the register will store respective values from the report with id = 1. In this example the E1.0 register will store event start time [UnixTime], E1.1 - event end time or 0 if event not finished yet, E1.2 - the value from register "Recipe" at the moment of event start.

ESxxx - Event State

Event state registers.

For example, value "1" in the ES2 register means that the event with id = 2 is now running. If the register ES2 = "0", then event is not active.

ELxxx - Event Length

Event length registers.

For example, the EL2 register will contain the duration in seconds of the event with id = 2, provided that this event is currently running. If the register EL2 is zero, then this means that the condition is not met or its duration is less than 1 second.

Sxxx - String

Since version 1.11.0.3478 in WebHMI, a new data type has been added-strings. The strings are available as internal Sxxx registers. A total of 200 such registers are available S1 ... S200.

TRxxx - Title of recipe

Since version 2.7 in WebHMI, a new type of internal registers TRxx has been added. They contain the names of recipes with the specified ID.

WCxxx - Weather Condition registers

Current meteorological information. A group of registers that provide current weather information at the WebHMI installation site. The data is updated approximately every two hours. The service requires an Internet connection, an account in Level2 and a subscription to the weather forecast. Registers are available since version 2.5.2400.

Textual description of the current weather can be on of these: Clear, Clouds, Rain, Snow, Thunderstorm, Mist.

WFxxx - Weather Forecast registers

Weather forecast for the next day with an interval of 3 hours. The forecast is available for seven 3-hour intervals ahead. The data is updated approximately every two hours. The service requires an Internet connection, an account in Level2 and a subscription to the weather forecast. Registers are available since version 2.5.2400.

The registers are the same as the WCxxx registers. Addresses of registers are constructed in this way: [interval number] * 10 + [register address WCxxx].

Example:
WF1 = Air temperature in the next 3 hours interval.
WF21 = Air temperature in the next 6 hours interval.
WF31 = Air temperature in the next 9 hours interval.
И т.д.

For a more accurate understanding of how long a forecast is built, you can use timestamps in the WFx0 registers.

Textual description of the current weather can be: Clear, Clouds, Rain, Snow, Thunderstorm, Mist.

WSxxx - Sunset/Sunrize registers

The time of sunrise and sunset in the current day. The service requires an Internet connection, an account in Level2 and a subscription to the weather forecast. Registers are available since version 2.5.2400.

A textual description of the current weather can be: Clear, Clouds, Rain, Snow, Thunderstorm, Mist.
