Configuration & Ladder Logic Example

Using an Allen-Bradley CompactLogix PLC

29.Each of the members shown above are passed implicitly to and from the gateway to the PLC with little to no programming.

Note:

If you are interested in learning more about how to change either of the implicit assemblies download the PM Communications manual from the Watlow website. Refer to step one for the link to Watlow’s website.

30.For ease in programming it is suggested (but not necessary) that two user defined data types be created reflecting the default assembly structures (or the user defined structure) as shown below. In the examples that follow two user defined data types will be used which correspond with the network architecture as shown in step 17 for both T to O and O to T assemblies.
