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.

|
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.

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.
Example: |
Min. time interval between two PDOs having the same COB |
|
ID: 30ms. |
|
Sub-index 3 = 300 = 0x12C |
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.
