C01 & C04 Pulses.rss: Setpoint Reading, Restoration, and Storage Program
Included with these instructions you will need the RS Logix PLC program C01 & C04 Pulses.rss. This program provides
a way to read setpoints from the PL-1746 as well as a setpoint storage medium, to use the same setpoints for more than
one controller. This program is intended for use with RS Logix 500 software, PL-1746 PL
µ
S Plug-In Module, and SLC
CPU 5/03 or higher. No input or output cards are necessary for this program to run properly, the only requirement is that
the SLC CPU is in Slot 0 and the PL-1746 is in Slot 1.
Prior to downloading and running the program, it must be configured for your setup the same way as described in the
C01 & C04 Example.rss PLC program initialization. Once the program has been configured and downloaded, use these
instructions to assist in setpoint reading and storage. The CDM shown below is the operational interface for setpoint
reading and restoration.
“Read” setpoints from PL-1746 to PLC PROGRAM
To ensure that the setpoints contained in your PL-1746 are not accidentally erased when making backups, follow these
steps to ‘Read’ setpoint information from the PL1746:
1. Ensure Key is in the ‘PROG’ state on your SLC CPU.
2. Download C01 & C04 Pulses.rss program into your SLC CPU.
3. Set B3/15 to ‘0’ (READ)
4. Turn the SLC CPU keyswitch to ‘RUN’.
5. Toggle B3/2 high (set to 1).
Once all setpoints have been downloaded from the SLC CPU, B3/2 will toggle back to ‘0’. To save these setpoints, go to
the upper left corner and click ‘File’, ‘Save as’- give the setpoints a name. Now the setpoints can be viewed in the Data
Files N10 through N25. Each setpoint takes up three integer words, ‘channel’, ‘on’ value and ‘off’ value. The data tables
are large enough to hold up to 1252 total setpoints. The more setpoints you have in the PL-1746, the more time it will take
to either read or write setpoints.
