每個(gè)部分最多可支持32個(gè)訂戶(hù)，總共可支持128個(gè)訂戶(hù)。
COMV
COMmunication Variable. This is the unit of exchange for I/O data on a FIP network.
A COMV has only one producer. It is distributed on the network and can be
consumed by all the other network subscribers. A COMV carries one or several
transport variables (TVAs).
Connection Point
A device is logically connected to a network segment by a connection point that
corresponds to a subscriber number. Only one logical connection point is permitted
per device.
Consumer
A device that consumes a system or application variable (or COMV) on the network.
Detailed Channel Status Words
This optional status data may be retrieved using the Retrieve Detailed Channel
Status Command.Fault Contacts
Logical contacts that can be included in the application program of the Series 90-70
PLC. These contacts can be used to detect fault and lack of fault conditions reported
by the FIP Bus Controller.
FIP
Factory Instrumentation Protocol
Full FIP Chip
The hardware component on the Series 90-70 FIP Bus Controller that manages
communications between the FIP Bus Controller and the network.
Generic Device
Term used to designate devices supporting Communication Standard EN 50170
(WorldFip profile). This includes third party devices that can be integrated into the
FIP system. A generic device exchanges data only with PLCs, operating Control
Stations or other generic devices. The exchange always consists of a table of bytes
carried in an MPS communication variable (COMV) that is identified by the user.
Macrocycle
The set of operations that occurs during one scan of the FIP bus.
Master Device
The operating modes of a remote I/O rack are controlled by the master device to
which it is attached. There is only one master device per remote I/O rack. However,
there can be several remote I/O rack master devices on the same network segment.In a FIP Network, all of the devices are also known as subscribers. One or more acts as
a Master Subscriber. The Master Subscriber stores configuration files to the subscribers,
controls the subscribers’ operating mode, and reports faults discovered on the network.
MPS (Manufacturing Periodic Services) Exchanges
MPS is one of the application layers of the FIP network. It consists, in particular, of
the notions of promptness and refresh.
The periodic MPS exchange is asynchronous if only the period of the exchange time
slot is defined by the user.
The periodic MPS exchange is synchronous if the period of the exchange time slot as
well as the earliest beginning moments and the latest ending moments of the time
slot are defined by the user.
Network Segment
A network segment can support up to four sections interconnected by repeaters.
Each section can support up to 32 subscribers, for a total of up to 128 subscribers.
