Defining the peripheral addresses of the S-Bus driver

For a mapping of the values that are read/written using the S-Bus driver, a _address (Peripheral address) is necessary, which can be defined inside the PARA Module. Following configurations can be done for the _address config.

Figure 1. Address Config of the S-Bus driver

Reference

Sets the reference device and address for the _address config. The reference is composed of the PLC and the corresponding address. (Format: < SBus device name>.<Address>). e.g. SBusDevice_1.F0 defines that the config should refer to the S-Bus device SBusDevice_1 and the address F0 (Flag 0) should be used.

PLC

The S-Bus data point, the DPE should communicate with.

Address type

Defines which address is accessed. Following address types are supported:

  • F (Flag)

  • R (Register)

  • X (Text)

  • DB (Data block)

The spin button is used to select the address that the DPE should use. e.g. SBusDevice_1.R3 represents the register number 3 in the S-Bus device SBusDevice_1.

Note

The format is analogous to the SAIA PG5: Fx, Rx, DBx.y and Xx.

Type of transformation

Defines the type of transformation (see Transformation).

When using the type of transformation "undefined", the type is automatically derived from the address. Rx and Dbx.y are interpreted as int32. The type of transformation can also be set explicitly to boolean, int32, uint32, float or string.

Direction

Represents the communication direction of the DPE and the PLC. Following directions are available:

  • Output => The DPE is sending values to the PLC

  • Input => The DPE is receiving values from the PLC

  • In/Out => The DPE is receiving as well as sending values from and to the PLC

Receive mode

The mode the DPE gets the values from the PLC. Following modes are available:

  • Polling => constantly retrieves the values from the PLC

  • Single query => retrieves the values from the PLC once

A single query must be triggered using a corresponding command, e.g. through passing a valid DPIdentifier to the DPE SQ of the S-Bus instance's internal DP _DriverCommon.

Example: Passing "System1:text." to the DPE SQ triggers a single query for the DP test.

Poll group

Predefined poll group which is used for polling values from the PLC

Poll groups

Allows to create and configure poll groups
