An instruction used to ensure that the operand bit is never turned ON for more
than one scan after the execution condition goes either from OFF to ON for a
Differentiate Up instruction or from ON to OFF for a Differentiate Down instruc-
tion.
A unit of storage in memory that consists of four bits.
Dual in-line package switch, an array of pins in a signal package that is mounted
to a circuit board and is used to set operating parameters.
A automation concept in which control of each portion of an automated system is
located near the devices actually being controlled, i.e., control is decentralized
and ‘distributed’ over the system. Distributed control is a concept basic to PC
Systems.
A data area used to hold only word data. Words in the DM area cannot be ac-
cessed bit by bit.
A word in the DM Area.
The process of transferring a program or data from a higher-level or host com-
puter to a lower-level or slave computer. If a Programming Device is involved,
the Programming Device is considered the host computer.
See data register .
A step in an SFC program that contains no actions, such as one used to transfer
execution to a subroutine.
Electrically erasable programmable read-only memory; a type of ROM in which
stored data can be erased and reprogrammed. This is accomplished using a
special control lead connected to the EEPROM chip and can be done without
having to remove the EEPROM chip from the device in which it is mounted.
Random variations of one or more electrical characteristics such as voltage, cur-
rent, and data, which might interfere with the normal operation of a device.
Extended Data Memory Area; an area that can be optionally added to certain
PCs to enable greater data storage. Functionally, the EM Area operates like the
DM Area. Area addresses are prefixes with E and only words can be accessed.
The EM Area is separated into multiple banks.
A step in SFC programming that begins a subchart or interrupt program.
A triangular symbol in SFC programming that comes before the entry step in a
subchart or interrupt program.
Erasable programmable read-only memory; a type of ROM in which stored data
can be erased, by ultraviolet light or other means, and reprogrammed.
A numeric code generated to indicate that an error exists, and something about
the nature of the error. Some error codes are generated by the system; others
are defined in the program by the operator.
An area in System DM that is used to store records indicating the time and nature
of errors that have occurred in the system.
A communication setting that adjusts the number of ON bits so that it is always
even. See parity .
