A position on a Rack (Backplane) to which a Unit can be mounted.
A dedicated Unit that is designed for a specific purpose. Special I/O Units
include Position Control Units, High-Speed Counter Units, Analog I/O Units,
etc.
The voltage/current that a relay can switch on and off.
All the PCs connected in series via SYSMAC LINK Units that can join
together to form data links or read and write data back and forth.
A Link System that contains two or more SYSMAC LINK Networks.
Programming instructions used to transfer data between PC connected in a
SYSMAC LINK Network or NET Link Subsystem. The write instruction acro-
nym is SEND(90) and is used to transfer data to another PC. The read
instruction acronym is RECV(98) and is used to receive data from another
PC.
The arrangement in which Units in a System are connected.
An error generated by the system, as opposed to one resulting from execution of
an instruction designed to generate an error.
An error message generated by the system, as opposed to one resulting from
execution of an instruction designed to generate a message.
The code comprising an asterisk and a carriage return (* CR) which indicates the
end of a block of data in communications between devices. Frames within a mul-
ti-frame block are separated by delimiters. Also a Unit in a Link System desig-
nated as the last Unit on the communications line.
The distance that a signal can be transmitted.
In OMRON PC terminology, the word Unit is capitalized to indicate any prod-
uct sold for a PC System. Though most of the names of these products end
with the word Unit, not all do, e.g., a Remote Terminal is referred to in a col-
lective sense as a Unit. Context generally makes any limitations of this word
clear.
A number assigned to some Link Units and Special I/O Units to assign words
and sometimes other operating parameters to it.
A program written by the user as opposed to programs provided with a product.
A timer within the system that ensures that the cycle time stays within specified
limits. When limits are reached, either warnings are given or PC operation is
stopped depending on the particular limit that is reached.
See watchdog timer .
A communications method in which signals are sent over wire cable.
Although noise resistance and transmission distance can sometimes be a
problem with wire communications, they are still the cheapest and the most
common, and perfectly adequate for many applications.
