Section 12. Program Control Instructions
12-14
Swath to Receive From Master
The number of data values that will be received from the host (master)
datalogger when data is transferred. If the host sends less than the number of
values indicated by the swath, the remaining locations will be filled with an
overrange value (-99999). If the host sends more than the number of data
values indicated by the swath, the extra values will be discarded by the local
datalogger.
First Location for Data Received
The first input location in which the first data value received from the host
(master) datalogger should be stored. Subsequent data values from the host will
be stored in consecutive input locations.
Notes:
The number of input locations required for the transferred data must be
allocated manually.
Security
Enter the level 2 security code for the master datalogger in the PakBus network
that will be communicated with using this instruction .
If the security code in this instruction does not match the security code of the
master datalogger, the master datalogger will discard the message, and the
failure will be indicated in the local datalogger by an incremental change in the
Result Code Location (parameter 8).
If security is not set in the master datalogger, this parameter can be left at 0.
For additional information on security codes, see Program Security.

Swath to Send
The number of data values that will be sent to the host (master) datalogger
when data is transferred.
First Location to Send
The input location which holds the first value that should be sent to the host
(master) datalogger. The range of values sent is determined by the Swath to
Send parameter (parameter 6).
