64 Configure the 1756-HSC Module
Set RPI
The Connection tab on the Module Properties dialog box lets you enter a
requested packet interval (RPI). The RPI guarantees the slowest rate at which
the pulse count values will be produced to the owner-controller.
The module’s actual data transfer rate may be faster than the RPI setting. But,
the RPI provides a defined, maximum period of time when data is transferred
to the owner-controller.
1. Choose from the options in the Connection tab.
