RSLogix5000 – Message Configuration using PLC5 or SLC Typed
Read/Write
This is an example of how to set up a message instruction to read or
write single or multiple elements from a power monitor using PLC5 or
SLC Typed messages. This setup applies to ControlLogix and
CompactLogix programmable logic controllers.
IMPORTANT
When performing a write to the power monitor, you must write
the password value to the password element of that specific
data table that you are writing to. This must be done in the
same message; therefore you must perform a multiple element
write. If you wish to perform only a single element write, you
must write the password value to the Single Element Password
Write table. This allows you to perform writes to any write
access data table for the next 30 minutes.
