1756-UM058C-EN-P, ControlLogix Digital I/O Modules User Manual

ControlLogix digital I/O modules are input/output modules that provide ON/OFF detection and actuation. Using the producer/consumer network model, they can produce information when needed while providing additional system functions.

The following is a list of the features available on ControlLogix digital I/O modules that allow greater system applicability.

• Removal and insertion under power (RIUP) - This system feature allows you to remove and insert modules and RTB while power is applied. For more information on RIUP, see page 1-6.

• Producer/consumer communications - These communications are an intelligent data exchange between modules and other system devices in which each module produces data without having been polled.

• System timestamp of data - A 64-bit system clock places a timestamp on the transfer of data between the module and its owner-controller within the local chassis.

• Module level fault reporting and field side diagnostic detection

• Class I Division 2, UL, CSA, FM and CE Agency CertificationControlLogix modules mount in a ControlLogix chassis and use a Removable Terminal Block (RTB) or a Bulletin 1492 Interface Module cable that connects to an IFM to connect all field-side wiring. Before you install and use your module you should have already:

• installed and grounded a 1756 chassis and power supply. To install these products, refer to the publications listed in Table 1.A.
