Communicate with Your ArmorBlock Module

This ArmorBlock module acts as a slave in a master/slave environment.

It is both a “polled device” and a “change of state device.”

When configured as a polled device, a master initiates communication

by sending its polled I/O message to the ArmorBlock module. The 4

output module consumes the message, updates outputs, and returns the

status of the output bits.

When configured as a “change of state” device, productions occur

when an output fault occurs. If none has occurred within the “expected

packet rate,” a heartbeat production occurs. This heartbeat production

tells the scanner module that the ArmorBlock module is alive and ready

to communicate.

Produces

00–03 Output fault bits – when the bit is set (1), the output is faulted. Bit

00 corresponds to output 0, bit 01 corresponds to output 1, etc.

04–07 Reserved

Consumes

00–03 Output bits – bit 00 corresponds to output 0, bit 01 corresponds to

output 1, etc.

0 = output is off; 1 = output on
