I/O assignment service

I/O assignment service guide

The I/O assignment service is used to assign I/O:s to other services and to retrieve information about available I/O:s and the services’ I/O requirements.

An I/O is a representation of how a combination of the door controller’s physical pins can be used. That is, an I/O is not the same as a physical pin.

To support as many different devices and combinations as possible, the door controller is designed to allow locks, readers, monitors and other external devices to be connected in different ways. When connecting a device, there are several possible combinations of pins that can be used; there are no specific pins that must be used. This does not mean that any device can be connected to any physical pin. Different pins have different electrical properties and devices must be connected to pins with the required electrical properties.

The API function axisio:GetIoInfoList provides information about the door controller’s available I/O:s and lists the physical pins used by each I/O. In some cases, the same physical pins are used by several different I/O:s. If so, only one of those I/O:s can be used at a time.

The I/O Assignment Service does not generate any events.

Assign I/O:s

Follow these steps to configure the door controller’s physical pins and assign I/O:s to services:

Configure the services that use I/O (section Configure the services that use I/O).
Get information about the services’ I/O requirements (section Get information about the services’ I/O requirements).
Get information about available I/O:s (section Get information about available I/O:s).
Assign I/O:s to the services (section Assign I/O:s to services).

Configure the services that use I/O

Before assigning I/O:s, the services that use I/O must be configured:

Door Control Service. See section Door control service guide.
IdPoint Service. See section IdPoint service guide.

Get information about the services’ I/O requirements

When the services that use I/O have been configured, use axisio:GetIoUserInfoList to retrieve information about the services’ I/O requirements, that is, what the services need I/O for.

The axisio:GetIoUserInfoList call returns a list of IoUserInfo:s. Each IoUserInfo corresponds to an I/O entity required by a service and consists of three parts:

Name is a nice name of the entity, for example “Door” or “Reader In”, which needs an I/O.
IoUser is the I/O specification required by a service.
1. Type is the name of the owner, for example the Door Control Service.
2. token belongs to the specific entity, for example Door or IdPoint, that will use the I/O.
3. Usage has information about what the entity needs the I/O for.
4. MultiIo specifies whether the IoUser can use multiple I/O:s.
IoMode gives information about which mode the I/O must support to be able to be assigned to the IoUser.

The following is an example output from axisio:GetIoUserInfoList:

In the example above, the Door requires an I/O that can be used in the “inout:12V/gnd” mode to use for its standard lock. However, the first IdPoint can use any I/O that supports any of four different modes to control its LED. The second IdPoint requires an I/O which support Wiegand.

Get information about available I/O:s

When the services’ I/O requirements are known, use axisio:GetIoInfoList to retrieve a list of the door controller’s available I/O:s. Each available I/O is represented by an IoInfo. The IoInfo consists of three parts.

IoName is the name of the I/O.
IoMode holds a list of which modes the I/O can be used with.
Pin holds a list of the physical pins on the door controller that this I/O will use if assigned to an IoUser.

All IoInfos can be retrieved with axisio:GetIoInfoList and the response is as follows:

  {"IoName": "IO1",
  "IoMode": ["inout:pu/gnd",
        "inout:float/gnd",

Assign I/O:s to services

The final step is to assign I/O:s to services. Using IoUsers and IoInfos, it is possible to assign I/O:s with IoAssignments. An IoAssignment consists of the following three parts:

IoName is the name of the IoInfo to assign.
IoMode is the mode of operation to set the I/O to. Available modes can be found in the IoInfo.
IoUser holds a list of IoUsers that should be assigned to the I/O.

The IoUserInfo must have the chosen IoMode in its list of IoModes to be able to assign it. When assigning multiple IoUsers to the same IoInfo, all of the IoUsers must be able to use the same mode, and that must also be the mode of the IoAssignment.

Note

Note that the MultiIo field of the IoUser is used to determine if the same IoUser can be assigned to several different IoInfos. It is not used to determine if several IoUsers can be assigned to the same IoInfo.

Assign one IoUser to one I/O:

Request

{"axisio:SetIoAssignment":{
  "IoAssignment": [ {
    "IoName":"H1",
    "IoMode":"inout:12V/gnd",
    "IoUser": [ {"MultiIo":false,
        "Type":"doorcontrol",
        "Usage":"Lock_Standard",
        "token":"Axis-0408c184bcc:1353672968.091740000"} ]
  } ] }
}

Request

<axisio:SetIoAssignment>
  <axisio:IoAssignment>
    <axisio:IoMode>inout:12V/gnd</axisio:IoMode>
    <axisio:IoName>H1</axisio:IoName>
    <axisio:IoUser>
      <axisio:MultiIo>false</axisio:MultiIo>
      <axisio:Type>doorcontrol</axisio:Type>
      <axisio:Usage>Lock_Standard</axisio:Usage>
      <axisio:token>Axis-0408c184bcc:1353672968.091740000</axisio:token>
    </axisio:IoUser>
  </axisio:IoAssignment>
</axisio:SetIoAssignment>

Assign several IoUser:s to one I/O:

Request

{"axisio:SetIoAssignment": {
  "IoAssignment": [ {
    "IoName":"IN1",
    "IoMode":"in:pu/gnd",
    "IoUser": [ {"MultiIo":true,
          "Type":"doorcontrol",
          "Usage":"DoorOpenMonitor",
          "token":"Axis-00408c184bcc:1353674725.635842000"},
          {"MultiIo":false,
          "Type":"doorcontrol",
          "Usage":"DoorClosedMonitor",
          "token":"Axis-00408c184bcc:1353674725.635842000"} ]
  } ] }
}

Request

<axisio:SetIoAssignment>
  <axisio:IoAssignment>
    <axisio:IoMode>in:pu/gnd</axisio:IoMode>
    <axisio:IoName>IN1</axisio:IoName>
    <axisio:IoUser>
      <axisio:MultiIo>true</axisio:MultiIo>
      <axisio:Type>doorcontrol</axisio:Type>
      <axisio:Usage>DoorOpenMonitor</axisio:Usage>
      <axisio:token>Axis-00408c184bcc:1353674725.635842000</axisio:token>
    </axisio:IoUser>
    <axisio:IoUser>
      <axisio:MultiIo>false</axisio:MultiIo>
      <axisio:Type>doorcontrol</axisio:Type>
      <axisio:Usage>DoorClosedMonitor</axisio:Usage>
      <axisio:token>>Axis-00408c184bcc:1353674725.635842000</axisio:token>
    </axisio:IoUser>
  </axisio:IoAssignment>
</axisio:SetIoAssignment>

This example is actually a common assignment using two different types of door monitors. One door monitor which checks if the door is open and one which checks if the door is closed. Sometimes, these are separate physical door monitors but sometimes only one physical door monitor is used for both purposes. If there is only one physical door monitor, the polarities of DoorOpenMonitor and DoorClosedMonitor should be configured to be the reverse of one another in the DoorControl service configuration, see Door control service. Both monitors should then be assigned to the same IoInfo. This ensures that one of them is always active and the other inactive. This configuration of two monitors using the same I/O behaves the same as if there was only one door monitor that switched between open and closed.

Assign one IoUser to several I/O:s:

Request

{"axisio:SetIoAssignment": {
  "IoAssignment": [ {
    "IoName":"H1",
    "IoMode":"inout:12V/gnd",
    "IoUser": [ {"MultiIo":true,
          "Type":"doorcontrol",
          "Usage":"Lock_Standard",
          "token":"Axis-0408c184bcc:1353672968.091740000"} ]
  }, {
    "IoName":"H2",
    "IoMode":"inout:12V/gnd",
    "IoUser": [ {"MultiIo":true,
          "Type":"doorcontrol",
          "Usage":"Lock_Standard",
          "token":"Axis-0408c184bcc:1353672968.091740000"} ]
  } ] }
}

Request

<axisio:SetIoAssignment>
  <axisio:IoAssignment>
    <axisio:IoMode>inout:12V/gnd</axisio:IoMode>
    <axisio:IoName>H1</axisio:IoName>
    <axisio:IoUser>
      <axisio:MultiIo>true</axisio:MultiIo>
      <axisio:Type>doorcontrol</axisio:Type>
      <axisio:Usage>Lock_Standard</axisio:Usage>
      <axisio:token>Axis-0408c184bcc:1353672968.091740000</axisio:token>
    </axisio:IoUser>
  </axisio:IoAssignment>
  <axisio:IoAssignment>
    <axisio:IoMode>inout:12V/gnd</axisio:IoMode>
    <axisio:IoName>H2</axisio:IoName>
    <axisio:IoUser>
      <axisio:MultiIo>true</axisio:MultiIo>
      <axisio:Type>doorcontrol</axisio:Type>
      <axisio:Usage>Lock_Standard</axisio:Usage>Lock_Standard
      <axisio:token>Axis-0408c184bcc:1353672968.091740000</axisio:token>
    </axisio:IoUser>
  </axisio:IoAssignment>
</axisio:SetIoAssignment>

Both “H1” and “H2” is assigned to the standard lock of the door with token “Axis 00408c184bcc:1353672968.091740000”. They would therefore both be triggered when changing the state of the standard lock for that door.

Unassign I/O:s

I/O:s are unassigned in two different situations. When an I/O is assigned, all other I/O:s using any of the pins required by the assignee, is unassigned. This implies that when assigning an I/O, several others may be unassigned automatically because the pins they use are needed by the I/O being assigned.

The other way I/O:s can be unassigned is by assigning that I/O with an empty IoUser. The following is an explicit unassignment of “IO3”:

Request

{"axisio:SetIoAssignment": {
  "IoAssignment": [ {"IoName":"IO3",
        "IoMode":"inout:pu/gnd",
        "IoUser":[] } ]
  }
}

Request

<axisio:SetIoAssignment>
  <axisio:IoAssignment>
    <axisio:IoMode>inout:12V/gnd</axisio:IoMode>
    <axisio:IoName>IO3</axisio:IoName>
  </axisio:IoAssignment>
</axisio:SetIoAssignment>
