segment
The combination of: a continuous length of trunk cable connecting
a pair of taps; the two taps; and the drop cables between the two
taps and their node devices. One or more segments form a section
of the network. See section and tap.
serial port
An communication port at which data is transferred one bit at a
time.
slave
A networked device which is controlled by another device. Slave
devices do not initiate data transactions. They respond to
commands or requests initiated by a master device. See master .
slot time
The amount of time representing the worst case time any station
on the network must wait for a response from another station. It
is based upon the response time of the network’s slowest station
and the bus propagation delay.
Specific Input
A type of data input received by a node using Peer Cop data
transfers. Nodes using Peer Cop can be configured to receive up to
32 16-bit words of Specific Input data from each of up to 64 source
nodes, up to a maximum total of 500 words. Nodes can be
configured to accept or ignore incoming data from specific source
nodes.
Specific Output
A type of data output sent by a node using Peer Cop data
transfers. Nodes using Peer Cop can be configured to send up to
32 16-bit words of Specific Output data to each of up to 64
destination nodes, up to a maximum total of 500 words.
splitter
A passive device that allows a cable to be routed into multiple
paths with essentially equal signal amplitude in each path. Not
used with Modbus Plus.
start delimiter
A field that defines the start of a frame, occurring after the signal
has been detected and synchronized by the receiving node. See
end delimiter .
