SynchLink Direct Data

Direct Data Receive Parameters (Follower)

Parameters 906 [SL Rx DirectSel0]…909 [SL Rx DirectSel3] select what you
want to do with direct received data. The available settings for these parameters
are:

• 0 “No Data” - SynchLink received data is passed straight through.

Parameters 929 [SL Dir Data Rx00]…932 [SL Dir Data Rx03] contain the
values for direct data received from SynchLink. When “No Data” is
selected, a destination parameter can be linked directly to the
corresponding direct data receive parameter (parameters 929…932).

• 1 “SL Multiply” - See details on

Multiply Block on page 183

.

• 2 “Event P0” - Parameter 917 [SL Rx P0 Regis] receives value from

registration latch 0 of transmitter.

• 3 “Event P1” - Parameter 918 [SL Rx P1 Regis] receives value from

registration latch 1 of transmitter. Event P1 is not functional over
SynchLink at the time of publication.

• 10 “Event Status” - Parameter 915 [SL Rcv Events] receives registration

found bits for registration latch 0/1 from registration of the transmitter.
Bit 0 is for registration latch 0 and bit 1 is for registration latch 1.

Parameter 928 [Rx Dir Data Type] bits 0…3 select whether the direct data words
received over SynchLink will be DInt (double integer) or real (floating point)
data. When the bit is turned off, the received data will be DInt data. When the bit
is turned on, the received data will be floating point data. The default is all DInt
words.

IMPORTANT

The clear bit in parameter 916 [SL Clr Events] of the receiving drive must
be toggled to clear the corresponding found bit in parameter 915 before
the receiving drive can receive a new value for the registration latch P0
or P1.
