Module Specific Commands
Both the HART input and output modules provide module specific
commands. The commands are passed to the module using unconnected
messaging. Unconnected messaging simply refers to the ability to
communicate to the module, over a control network (i.e. CNET, Ethernet,
Etc.), without the need of the owner PLC. However, an unconnected
message can be sent from a PLC to the HART module using the MSG
ladder instruction. See figure below.
Figure 7.7 (Message Instruction)
The MSG instruction must be configured correctly to establish
communication to the HART module. Each module specific command
uses the same generic CIP message configuration. The generic CIP
message configuration used by the HART input and output module is
shown in the table below.
