3. Remove interface module. Place the module in RUN mode by
setting JW4 as follows:
4. Insert module. Power the chassis.
For details about alternatively configuring the series B interface
module from the SLC through the backplane, see the DH-485/RS-232C
Interface Module User Manual, publication 1747-6.12.
Messaging SLC 5/01 processors and the fixed controllers can only respond to a
master station. These processors cannot initiate messages on their
own.
Messaging in an SLC 5/02 processor can occur between:
•
a master station and a remote station. (For more information see
the chapter pertaining to the master device you are using.)
•
a remote station and its master station (see Polled
Report-by-Exception).
•
between two processors connected via a point-to-point link.
Polled Report-by-Exception
A remote station can gather information from the I/O points it is
responsible for and can send any anomalous readings to the master
station. To do this, write logic in the remote station’s processor to
monitor certain conditions and send the data in an MSG instruction to
the master station. Figure 5.7 is an example MSG instruction and
control block that an SLC 5/02 processor in a remote station can send
to a PLC-5 master station.
