Value: 0: PKW 0 words
3: PKW 3 words
4: PKW 4 words
127: PKW variable
Dependency: Refer to: p2030
Note: The parameter is not influenced by setting the factory setting.
Description: Sets the time values for the fieldbus interface.
The following applies for MODBUS:
p2024[0]: Maximum permissible telegram processing time of the MODBUS slave in which a reply is sent back to the
MODBUS master.
p2024[1]: Not relevant.
p2024[2]: Telegram pause time (pause time between two telegrams).
The following applies for BACnet:
p2024[0]: APDU timeout.
p2024[1, 2]: Not relevant.
Index: [0] = Max. processing time
[1] = Character delay time
[2] = Telegram pause time
Dependency: Refer to: p2020, p2030
Note: Re p2024[2] (MODBUS):
If the field bus baud rate is changed (p2020), the default time setting is restored.
The default setting corresponds to a time of 3.5 characters (dependent on the baud rate that has been set).
Description: Sets the communication parameters for BACnet.
p2025[0]:
Device object instance number (0 ... 4194303).
p2025[1]:
Maximum number of info frames (1 ... 10).
p2025[2]:
Number of APDU retries (0 ... 39).
p2025[3]:
Maximum master address (1 ... 127).
Index: [0] = Device object instance number
[1] = Maximum number of info frames
[2] = Number of APDU retries
[3] = Maximum master address
Dependency: Refer to: p2030
