ArmorBlock-LP 8 Output Module 7
Publication 1792-5.7 – December 1997
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 Connections Consumes Produces
Polled 1 Bytes 1 Byte
Bit Strobe 0 Bytes 1 Byte
Change of State 0 Bytes 1 Byte
Polled device – a master initiates communication by sending its polled
I/O message to the ArmorBlock module. The 8 output module consumes
the message, updates outputs, and produces a response that reflects the
status of its output faults.
Change of state device – productions occur when a fault condition
changes. If no fault condition occurs 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 8 output
module consumes the message, and produces a response that reflects the
status of output faults.
