Communicate with Your ArmorBlock Module
This ArmorBlock module’s I/O is exchanged with the master through a
poll, bit strobe or change of state connection.
When set for Polled, Bit Strobe, or change of state, the module consumes
and produces as follows:
Type of I/O
Connection
Consumes Produces
Polled 0 Bytes 3 Bytes
Bit Strobe 0 Bytes 3 Bytes
Change of State 0 Bytes 3 Bytes
Polled device – a master initiates communication by sending its polled
I/O message to the ArmorBlock module. The 16 input module scans the
inputs and fault bit producing a response that reflects their status.
Change of state – productions occur when an input changes or an input
source voltage fault occurs. If neither 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.
Bit Strobe device – a master initiates communication by sending its bit
strobe I/O message. All bit strobed devices then respond. The 16 input
module scans the inputs and fault bits, producing a response that reflects
their status.
