I/O Terminal
An interface used to connect a C-series PC to a host computer in a Host Link
System.
The process by which the PC assigns certain bits in memory for various func-
tions. This includes pairing I/O bits to I/O points on Units.
A bit in memory used to hold I/O status. Input bits reflect the status of input termi-
nals; output bits hold the status for output terminals.
Either an Input Block or an Output Block. I/O Blocks provide mounting positions
for replaceable relays.
The number of inputs and outputs that a PC is able to handle. This number
ranges from around one hundred for smaller PCs to two thousand for the largest
ones.
A comment in a program that is related to the use of operands.
A Unit mounted to the CPU Rack to monitor and control I/O points on Expansion
CPU Racks or Expansion I/O Racks.
The delay in time from when a signal is sent to an output to when the status of the
output is actually in effect or the delay in time from when the status of an input
changes until the signal indicating the change in the status is received.
A device connected to the I/O terminals on I/O Units, Special I/O Units, etc. I/O
devices may be either part of the Control System, if they function to help control
other devices, or they may be part of the controlled system.
A Unit mounted to an Expansion CPU Rack or Expansion I/O Rack to interface
the Rack to the CPU Rack.
An interrupt generated by a signal from I/O.
An entry terminal for an I/O interrupt program.
A return terminal for an I/O interrupt program.
A name assigned to a bit or word used in a program that can be used to input the
bit or word, or can be displayed to indicate the bit or word on a monitor.
The place at which an input signal enters the PC System, or at which an output
signal leaves the PC System. In physical terms, I/O points correspond to termi-
nals or connector pins on a Unit; in terms of programming, an I/O points corre-
spond to I/O bits in the IR area.
The process of updating output status sent to external devices so that it agrees
with the status of output bits held in memory and of updating input bits in memory
so that they agree with the status of inputs from external devices.
The time required for an output signal to be sent from the PC in response to an
input signal received from an external device.
A table created within the memory of the PC that lists the I/O words allocated to
each Unit in the PC System. The I/O table can be created by, or modified from, a
Programming Device.
A Remote I/O Unit connected in a Wired Remote I/O System to provide a limited
number of I/O points at one location. There are several types of I/O Terminals.
