5.3.4.2.20Object 0x1400– 0x141F, Receive PDO Communication Parameter

This object is used to set the communication parameters of the RxPDOs. 32 RxPDOs are supported. The default COB IDs of the first four PDOs are preassigned according to the DS301 standard. All further PDOs are deactivated. If not all default PDOs are used (i.e. a smaller number of modules is connected), also the default PDOs not used are deactivated.

Design COB-ID:

If a new COB ID is to be entered, bit 31 must be set to 1 first, because the DS301 standard does not permit to change a valid COB ID (Bit31=0).

A mode can be defined for each PDO for the purpose of data transmission (transmission type in the Index Communication Parameter). As standard, digital and analog inputs are transmitted as ´Change of Value´(COV). The type of transmission depending of the set transmission type is explained in the following table.

1 the data is transmitted at the interval of the set inhibit time

5.3.4.2.21Object 0x1600– 0x161F, Receive PDO Mapping Parameter

This object is used to define the data, which is to be transmitted by means of the PDO.

Sub-index 0 contains the number of objects valid for the PDO.

Design 1. to 8. Object:

64(8Byte*8Bit)

5.3.4.2.22Object 0x1800– 0x181F, Transmit PDO Communication Parameter

This object is used to set the communication parameters of the TxPDOs. 32 TxPDOs are supported. The default COB IDs of the first four PDOs are preassigned according to the DS301 standard. All other PDOs are de-activated. If not all default PDOs are used (i.e. a smaller number of modules is connected), also the default PDOs not used are de-activated.

Inhibit Time shows the min. time between two consecutive PDOs having the same COB ID. One time unit is 100us. The transmitted value is internally rounded to the next smaller milli-second.

Network Communication

If a new value is to be entered, the COB ID has to be set invalid (Bit 31 = 1), because the DS301 standard does not permit to enter a new time when the COB ID (Bit31=0) is valid.

The Event Timer defines the time after the elapse of which a PDO is sent, even if no change of the PDO data has occurred. Enter the time in milliseconds. The timer is re-started whenever an event occurs (change to the PDO data).

If the time is shorter than the inhibit time, a new event is generated once the inhibit time has elapsed!

Attention

The event timer can only be used for the transmission types 254/255.

Attention

An object entry can only be mapped in a max. of 3 different PDOs.

5.3.4.2.23Object 0x1A00 – 0x1A1F, Transmit PDO Mapping Parameter

This object is used to define the data, which is transmitted using the PDO.

Sub-index 0 contains the number of objects valid for the PDO.

5.3.4.3 Manufacturer Specific Profile Area

The non-standard device profile-specific I/O functionality of special modules and other modules as well as special functions (i.e. spacer module configuration,...) are imaged in the ‘Manufacturer Specific Area’ profile. The objects defined there provide data word widths of a modularity from 1 to 8 bytes. The indexes 0x2000 (digital inputs), 0x2100 (digital outputs), 0x2400 (2 byte special module inputs) and 0x2500 (2 byte special module outputs) are mirror imaged by the corresponding indexes of the device profile DS 401 (0x6000, 0x6200, 0x6401, 0x6411). This means for instance: object 0x2000 and object 0x6000 refer to the same memory places in the process image.

The following table shows all objects of the manufacturer profile supported by the bus coupler.
