8 ArmorBlock MaXum 4 Output Module Series B

Publication 1792D-IN040B-EN-P - September 2000

Communicate with Your ArmorBlock MaXum I/O

Module

This ArmorBlock module’s I/O is exchanged with the master through

a cyclic, poll, or change-of-state connection.

The module consumes and produces output data as follows:

Cyclic - allows configuration of the block as an I/O client. The block

will produce and consume its I/O cyclically at the rate configured.

Polled - a master initiates communication by sending its polled I/O

message to the module. This 4 output module consumes the

message, updates outputs, and produces a response. The response

has output faults and contains the status of the Auxiliary power.

Change-of-State - productions occur when an output changes or a

fault condition occurs. If no output or fault condition change occurs

within the expected packet rate, a heartbeat production occurs. This

heartbeat production tells the scanner module that the I/O module is

alive and ready to communicate.

Refer to the table below for the word/bit definitions.

Output no load or overload fault (OFLT): - When the bit is set

(1), an output fault has occurred. OFLT0=outpout 0,

OFLT1=output 1, OFLT2=output 2, OFLT3=output 3.

Reserved

Output Power Fault (OPWR): When the bit is set (1),

Auxiliary Power is not present.
