T1

T2

T3

SlotTime V(ST)

This is the preset value for the SM service timeout timer in 1/32 of a millisecond ticks. It defines the time which the SM kernel of the host will wait for a response to an SM request to the field device. If the timer expires the service will be aborted with a negative response. Its purpose is to ensure that devices responding to system management requests have sufficient time to carry out necessary actions and transmit a response. For a description of the relationship between the three timers refer to T3.

This is the preset value for the SM set address sequence timer in 1/32 of a millisecond ticks. The timer T2 is a sequence duration timer. Its purpose is to guarantee that incorrectly executed or incomplete sequences are aborted in the System Management Kernel of the device. For a description of the relationship between the three timers refer to T3.

This is the preset value for the set address wait timer in 1/32 of a millisecond ticks. This time is used by the SM kernel of the host after a new address was assigned to a field device to wait before checking for the field device at the new node address. The relationship between the three timers T1, T2 and T3 is important for the host and the device to set the address of a field device correctly. T1 and T3 will be used on the host side, T2 within the field device. If the value for T2 is too small a new address cannot be assigned to the field device because the timeout is too small. T2 should always be >= T3 + 3*T1 of the host.

Device capability for how fast the device can reply upon receipt of a PDU. This capability is measured in MaxResponseDelay SlotTimes, V(MRD) × V(ST). Both parameters are specified in octet durations. The attributes SlotTime and MaxResponseDelay should be set such that the device represents the maximum response delay in octets of the device. The capability can be obtained from the devices 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.
