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￿
