desirable to delay execution of subsequent instructions if those instructions
perform further processing on the response from the remote.
Security
Enter the level 2 security code for the remote datalogger in the PakBus network
that will be communicated with using this instruction when Command 22 is
used for parameter 3 (send input location data to another datalogger).
If the security code in this instruction does not match the security code of the
remote datalogger, the remote 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 remote datalogger or if command 21 is used for
parameter 3, this parameter can be left at 0.
For additional information on security codes, see Program Security.

Remote Location/Coil/Register
PakBus Communication
If data is being received from another datalogger in the PakBus network
(Parameter 3 set to 21), this is the first input location in the remote datalogger
from which to retrieve the data.
If data is being sent to another datalogger in the PakBus network (Parameter 3
set to 22), this is the first input location in the remote datalogger in which to
store the first data value.
If a variable in the Public (or Input Locations) table is being accessed using Get
Value or Set Value (Parameter 3 set to 26 or 27), this parameter is left blank
and Instruction 63 or 68 is used following this instruction to enter the variable
name.
Modbus Communication
This is the first coil or register to be acted upon when the instruction is
executed.
