V(MRD)

MinInterPD UDelay

MaxResponseDelay SlotTimes, V(MRD) × V(ST). Both parameters are specified in octet durations. The attributes MaxResponseDelay and SlotTime should be set such that the device represents the maximum response delay in octets of the device. The capability can be obtained from the device’s CFF file. When configuring an H1 Link the maximum value of the product SlotTime × MaxResponseDelay of all devices residing on that link should be the minimum value for the Link configuration. This is to assure that all devices participate on the bus.

This parameter specifies the minimum interval between two frames on the H1 link. The minimum value of MinInterPDUDelay which a device is able to support is described in the CFF file of a device. When configuring the H1 link the minimum value that can be used for MinInterPDUDelay is the maximum of the values from the CFF files of the used devices.

Max. value of the capabilities of the H1 link and all H1 devices on the link shall be configured.

This parameter specifies the maximum scheduling overhead permitted an LAS DLE by the existing link schedule. The parameters unit is the transmission

MaxSchedul duration of one octet. This overhead is included in the ingOverhea time allocated for each scheduled activity, and so is d V(MSO) used only during schedule construction and

determination of whether a DLE can serve as LAS for an existing schedule. An H1 device capable value of V(MSO) will be checked with the configured value in the LAS domain during download of the domain.

Each frame on the H1 link starts with a preamble octet which is used by the receiving nodes (Devices) to synchronize to the signal clock. The number of preamble(s) can be extended when setting this parameter. The default value is 0. Networks including digital repeaters may require larger values.

The parameter defines the physical layer induced delay between the end of the last octet of one data link frame as it appears on the link, and the beginning of the first octet of any other data link frame as it appears on the link.

7.2 Bus parameters relevant for H1 Links

The following bus parameters are additionally relevant for configuration of H1 Links or a Link master device.

Determines how long a device can hold a token, i.e.

how much time the device can use for acyclic bus traffic 276 - 65000 (Client/Server connections, SM services and

alarms/events.

As the accuracy of the LAS schedule has the highest

priority, the remaining time for granting the token might 2 - 32767 be less than DefTokenHoldTime. In this case the token
