Application Variable
Set of application data put on the network segment which may be grouped together
in communication variables (COMVs).
Association
A link created between a device configuration in the Network Configuration Tool
and a rack system described in the Hardware Configuration Tool.
Bus Arbiter
In every FIP Network, one or more of the FIP devices must act as Bus Arbiter. The
Bus Arbiter is the device that controls access to the FIP Network. Without a Bus
Arbiter no data can be exchanged on a FIP Network.
Bus Interface Unit
A DIN-rail mounted unit that interfaces Field Control I/O modules to a FIP bus.
Bus Controller
The FIP Bus Controller is a rack-mounted PLC module that interfaces the PLC to a
FIP bus or busses.Bus Controller Status Bits
An 80-bit status area in the PLC reference table for Bus Controller, network, and
channel status data. The location of this status area is assigned during hardware
configuration of the Bus Controller.
Bus Scan
The FIP Bus Scan involves the constant repetition of the FIP macrocycle. The FIP
macrocycle is executed by the FIP Bus Arbiter. The Series 90-70 FIP Bus Controller
may be a potential Bus Arbiter in a FIP network. The macrocycle is generated by the
configuration software based on the configuration of the remote devices and their
associated I/O modules, and other user input.
Channel Status Bits
The Channel Status bits are bits 17-80 of the Bus Controller Status Bits. They consist
of an error bit and a data transfer bit for each of the 32 potential communications
channels that can be established.
COMREQ
A “Communications Request” that can be included in the application program of the
Series 90-70 PLC. Many different types of COMREQs have been defined for the
Series 90-70 PLC. Some COMREQs can be used to send commands from the PLC
CPU to the FIP Bus Controller.
COMREQ Command Block
This structure contains information about the FIP command to be executed.
COMREQ Status Word
A selected area in Series 90-70 memory where the results of the COMREQ are
placed.
