Rockwell Automation 1336-GM6 Enhanced DeviceNet Communications Module - Manual (Page 69)

Ladder Logic Programming 6-7
SLC Ladder Logic Program Example
The following example uses a SLC-5/03, a 1747-SDN DeviceNet
scanner, and a 1203-GU6 to control a 1336 PLUS, 1336 PLUS II or
1305 drive.
The example assumes that there is an operator’s station wired to an
I/O module in slot one of module group zero of rack zero.
Important: You may want to verify a device has not failed using
word I:S.0. If a device has failed, read the appropriate M1 File to find
out which device failed. Refer to the 1747-SDN DeviceNet Scanner
Module Manual, Publication 1747-5.8, for more information.
Figure 6.3 Example SLC Ladder Logic Program
The scanner gathers drive status information via DeviceNet.
The M-File is copied into the SLC’s N9 data file to move the drive status information into a convenient location.
